Abstract:
For soft grippers to be applied in atypical industrial environments, they must conform to an object’s exterior shape and momentarily change their stiffness. However, many of the existing grippers have limitations with respect to these functions: they grasp an object with only a single curvature and a fixed stiffness. Consequently, those constraints limit the stability of grasping and the applications. This paper introduces a new multicurvature, variable-stiffness soft gripper. Inspired by the human phalanx and combining the phalanx structure and particle jamming, this work guarantees the required grasping functions. Unlike the existing soft pneumatic grippers with one curvature and one stiffness, this work tries to divide the pressurized actuating region into three parts to generate multiple curvatures for a gripper finger, enabling the gripper to increase its degrees of freedom. Furthermore, to prevent stiffness loss at an unpressurized segment, this work combines divided actuation and the variable-stiffness capability, which guarantee successful grasping actions. In summary, this gripper generates multiple grasping curvatures with the proper stiffness, enhancing its dexterity. This work introduces the new soft gripper’s design, analytical modeling, and fabrication method and verifies the analytic model by comparing it with FEM simulations and experimental results.

Abstract:
Grippers are attached at the end of an industrial arm robot for material handling purpose. Grippers plays a major role in all pick and place application industries. Those are connected as end effectors to realize and develop a task in an industrial work floor. Pneumatic gripper works with the principle of compressed air. The gripper is connected to a compressed air supply. When air pressure is applied on the piston, the gripper gets opened while the air gets exist from the piston it gets closed. It is possible to control the force acting on the gripper by controlling the air pressure with the help of the valve. The objective is to design an effective, simple, and economic gripper for pick and place application.

Abstract:
The gripper is the most important part in an industrial robot. It is related with the environment around the robot. Today, the industrial robot grippers have to be tuned and custom made for each application by engineers, by searching to get the desired repeatability and behaviour. Vacuum suction is one of the grippers in Watch Case Press Production (WCPP) and a mechanism to improve the efficiency of the manufacturing procedure. Pick and place are the important process for the annealing process. Thus, by implementing vacuum suction gripper, the process of pick and place can be improved. The purpose of vacuum gripper other than design vacuum suction mechanism is to compare the effectiveness of vacuum suction gripper with the conventional pick and place gripper. Vacuum suction gripper is a mechanism to transport part and which later sequencing, eliminating and reducing the activities required to complete the process. Throughout this study, the process pick and place became more effective, the impact on the production of annealing process is faster. The vacuum suction gripper can pick all part at the production which will lower the loss of the productivity. In conclusion, vacuum suction gripper reduces the cycle time about 20%. Vacuum suction gripper can help lower the cycle time of a machine and allow more frequent process in order to increase the production flexibility.

Abstract:
Abstract. In light of technological advances, researchers have lost sight of robotic grippers/end effectors design intent. In a semi-structured environment the biomimetic approach is impractical due to the high complexity of the mechanism and control algorithms. Current industrial grippers are robust, but lack the flexibility that allows for in hand manipulation. The authors believe that underactuated grippers provide the best approach to allow for in hand manipulation along with being rugged enough for an industrial setting. Thinking of the robotic gripper and the robotic arm as one system (as opposed to two separate subsystems), one is capable of using the degrees of freedom of the robot in conjunction with that of the gripper to provide the desired motion profile without the complexity of running two subsystems. This paper will outline where recent grippers have failed and will introduce a new design paradigm for grippers along with several underactuated gripper ideas. This paper was presented at the IFToMM/ASME International Workshop on Underactuated Grasping (UG2010), 19 August 2010, Montréal, Canada.

Abstract:
Ensuring the necessary accuracy of positioning the objects of manipulation of Bernoulli's grippers in robotic cells is an urgent task and can be achieved by choosing rational parameters of the gripping process. The article conducts experimental studies of the process of handling by Bernoulli grippers of objects of manipulation at different operating parameters and their weight. For this purpose, an experimental setup was developed, which consists of an industrial robot IRB 4600, an IRC5 controller, a Raspberry Pi microcontroller and two clock-type micrometers. The method of determining the total positioning error of the "robot-gripper-object" system is presented, which takes into account the positioning errors of the industrial robot, the errors of the gripping device and the errors of basing the object of manipulation relative to the axis of symmetry of the gripping device. The ABB IRB 1600 industrial robot was programmed in the ABB RobotStudio environment to cyclically simulate the handling operation and to determine the deviation of the position of the manipulation object after its gripping from different distances. The first cycle of automatic mode was used to calibrate the micrometer indicators, while gripping the object was carried out from a distance of 0.02 mm. For better reliability of research results, 20 measurement cycles were performed for each of the variable parameters. As a result, it was found that the maximum base error of objects does not exceed 0.4 mm. When capturing objects from a distance of 0.5…1 mm, the mean value of the base error will be 0.08…0.15 mm, with a standard deviation of 0.025…0.035 mm. The paper studies the effect of the displacement Δ of the center of mass of the gripped object relative to the axis of the Bernoulli gripper on the accuracy of the base of the objects. It is established that when the center of mass of the gripped objects is shifted relative to the Bernoulli gripper axis up to 20 mm, the maximum base error of the objects increases 2.2 times.

Abstract:
Robotic manipulation, an area inside the field of industrial automation and robotics, consists of using a robotic arm to guide and grasp a desired object through actuators such as a vacuum or fingers, among others. Some objects, such as fragile ceramic pieces, require special attention to the force and the gripping method exerted on them. For this purpose, two grippers were developed, where one of them is a rotary vacuum gripper and the other is an impact gripper with three fingers, each one equipped with a load sensor capable of evaluating the values of load exerted by the grip actuators onto the object to be manipulated. The vacuum gripper was developed for the purpose of glazing a coffee saucer and the gripper with three fingers was developed for the purpose of polishing a coffee cup. Being that the impact gripper with sensorial feedback reacts to the excess and lack of grip force exerted, both these grippers were developed with success, handling with ease the ceramic pieces proposed.

Abstract:
The aim of presented work was to analyse the feasibility of using 3D-print technology in robotics based on the production of industrial robot flexible grippers. For selected geometry of gripper single finger available 3D printing techniques has been analysed. The study made by authors uses the following additive technologies and devices: SLS (Selective laser Sintering) and FDM (Fused deposition modelling). As a prior an analyses of capabilities of individual technologies were done by testing the quality of the 3D CAD model recreated on test print-outs. Based on the printed gripper, its functionality, and strength properties were examined. Strength of grapplers was tested with a use of an MTS test machine under repeating deflexion simulating standard operational cycle of a gripper. Test proved that at least few thousands of cycle are possible to be made by a 3D printed gripper. What interesting gripper made with use of the less advanced printer showed different wear behaviour than an one made on the more advanced. First one showed almost instantaneous start of slow and constant strength degradation while the second one proved to have a stable deflexional capability by almost twice an number of cycles. More isotropic structure of an SLS printed gripper caused the best results of all tested ones.

Abstract:
Anthropomorphic grippers for robots are used increasingly in robotic applications for handling and assembly. Currently there are several versions of anthropomorphic grippers as projects, prototypes or commercial variants that due to high prices or even for very high ones, are not available for current applications. Among them, high functionality at a relatively low complexity can be noticed in the case of reconfigurable grippers with high reconfigurability, Barrett Hand type. In this context, it is justified finding alternative solutions at lower prices at a lower reconfigurability, with acceptable functionality for current robotic operations. The paper presents an original version of modular anthropomorphic gripper continuous average reconfigurability, with three fingers. There are mentioned, briefly, major structural, kinematic and static issues, a CAD model and CAD simulation for gripping several types of pieces. Furthermore, we intend to achieve a prototype and test it by mounting on an industrial robot.

Abstract:
The human hand is a great generic gripper as it can grasp objects of unknown shapes, weights and surfaces. Most robotic grippers in today's industry have to be custom made and tuned for each application by engineers, thus many man hours are required to get the desired behavior and repeatability. To be able to adapt some of the capabilities of the human hand into robust industrial robotic grippers would enhance their usability and ease the tuning by engineers once installed. This thesis discusses the development of a robust intelligent gripper for industrial use, based on piezo sensors which have the ability to both sense slippage and detect objects. First, an experimental sensor prototype was developed successfully using an amplification circuit and algorithms implemented in LabView. Secondly, a final prototype containing a signal board, an FPGA board, a simple gripper with linear units and more robust sensor modules where developed. The thesis further discusses which parts of the intelligent gripper that have been successfully implemented within the project time frame and which parts that needs to be further implemented, tested and improved.
Den mänskliga handen är en fantastisk universiell gripklo då den kan greppa objekt av okänd form, vikt och yta. De flesta gripklor i dagens industri måste vara specialgjorda och anpassas för varje applikation av ingenjörer och därmed behövs otaliga mantimmar för att få önskat beteende och repeterbarhet. Att kunna anpassa vissa av den mänskliga handens egenskaper till en robust industriell robotgripklo skulle utöka dess användarområde och lätta upp anpassningen för ingenjörer när den väl är installerad. Detta examensarbete diskuterar hur en robust intelligent gripklo har blivit utvecklat for industriellt bruk baserad på piezo sensorer som har förmågan att känna av glidning och initiell kontakt av objekt. Först, en experimentiell fungerande sensorprototyp utvecklades med hjälp av en förstärkningskrets och algoritmer implementerade i LabView. Därefter utvecklades en slutlig prototyp innehållandes ett signalkort, ett FPGA-kort, en enkel gripklo med linjärenheter och mer robusta sensorer. Examensarbetet tar vidare upp vilka delar som framgångsrikt blivit implementerade och vilka delar som behöver utvecklas ytterligare, testas och förbättras.

Abstract:
A novel robot gripper control system is presented which uses PVDF piezoelectric sensors to actively damp exerted force. By using a low-input-resistance amplifier to sense the current developed by the PVDF sensor, an output proportional to the rate of change of the force exerted by the gripper is obtained. The signals from the PVDF sensor and a strain gauge force sensor are arranged in a proportional and derivative (PD) control system for the control of force. The control system was tested on an instrumented Rhino XR-1 manipulator hand. The capabilities of the control system are analyzed analytically, and verified experimentally. The results for this particular gripper indicate that as much as 900% improvement in force step response rise time, and 300% reduction in overshoot are possible by inclusion of the PVDF sensor.

Abstract:
Intelligent gripping may be achieved through gripper design, automated part recognition, intelligent algorithm for control of the gripper, and on-line decision-making based on sensory data. A generic framework which integrates sensory data, part recognition, decision-making and gripper control to achieve intelligent gripping based on ABB industrial robot is constructed. The three-fingered gripper actuated by a linear servo actuator designed and developed in this project for precise speed and position control is capable of handling a large variety of objects. Generic algorithms for intelligent part recognition are developed. Edge vector representation is discussed. Object geometric features are extracted. Fuzzy logic is successfully utilized to enhance the intelligence of the system. The generic fuzzy logic algorithm, which may also find application in other fields, is presented. Model-based gripping planning algorithm which is capable of extracting object grasp features from its geometric features and reasoning out grasp model for objects with different geometry is proposed. Manipulator trajectory planning solves the problem of generating robot programs automatically. Object-oriented programming technique based on Visual C++ MFC is used to constitute the system software so as to ensure the compatibility, expandability and modular programming design. Hierarchical architecture for intelligent gripping is discussed, which partitions the robot’s functionalities into high-level (modeling, recognizing, planning and perception) layers, and low-level (sensing, interfacing and execute) layers. Individual system modules are integrated seamlessly to constitute the intelligent gripping system.

Abstract:
Automation of the industrial transformer core assembly process is highly desirable. A survey undertaken by the author however, revealed that due to the high cost of existing fully automated systems, Australian manufacturers producing low to medium transformer volumes continue to maintain a manual construction approach. The conceptual design of a cost-effective automation system for core assembly from pre-cut lamination stacks was consequently undertaken. The major hurdle for automating the existing manual process was identified as the difficulty in reliably handling and accurately positioning the constituent core laminations, which number in their thousands, during transformer core construction. Technical evaluation of the proposed pick-and-place core assembly system, incorporating two mobile robots bearing a common gripper, is presented herein to address these requirements. A unique robotic gripper, having the capability to selectively pick a given number of steel laminations (typically two or three) concurrently from a stack, has the potential to significantly increase productivity. The only available avenue for picking multiple laminations was deemed to be a gripper based on magnetism. Closed form analytical and finite element models for an electromagnet-stack system were contrived and their force distributions obtained. The theoretical findings were validated by experiment using a specially constructed prototype. Critical parameters for reliably lifting the required number of laminations were identified and a full scale electromagnet, that overcame inherent suction forces present in the stack during picking, was subsequently developed. A mechanical docking arrangement is envisaged that will ensure precise lamination placement. Owing to the grippers unwieldy length however, conventional robots cannot be used for assembling larger cores. Two wheeled mobile robots (WMRs) compliantly coupled to either end of the gripper could be considered although a review of the current literature revealed the absence of a suitable controller. Dynamic modelling for a single WMR was therefore undertaken and later expanded upon for the dual WMR system conceived. Nonlinear adaptive controllers for both WMR systems were developed and subsequently investigated via simulation. Neglecting the systems dynamics resulted in analogous, simplified kinematic control schemes, that were verified experimentally using prototypes. Additional cooperative control laws ensuring the synchronisation of the two robots were also implemented on the prototype system.

Abstract:
Artificial hands or grippers are essential elements in many robotic systems, such as, humanoid, industry, social robot, space robot, mobile robot, surgery and so on. As humans, we use our hands in different ways and can perform various maneuvers such as writing, altering posture of an object in-hand without having difficulties. Most of our daily activities are dependent on the prehensile and non-prehensile capabilities of our hand. Therefore, the human hand is the central motivation of grasping and manipulation, and has been explicitly studied from many perspectives such as, from the design of complex actuation, synergy, use of soft material, sensors, etc; however to obtain the adaptability to a plurality of objects along with the capabilities of in-hand manipulation of our hand in a grasping device is not easy, and not fully evaluated by any developed gripper. Industrial researchers primarily use rigid materials and heavy actuators in the design for repeatability, reliability to meet dexterity, precision, time requirements where the required flexibility to manipulate object in-hand is typically absent. On the other hand, anthropomorphic hands are generally developed by soft materials. However they are not deployed for manipulation mainly due to the presence of numerous sensors and consequent control complexity of under-actuated mechanisms that significantly reduce speed and time requirements of industrial demand. Hence, developing artificial hands or grippers with prehensile capabilities and dexterity similar to human like hands is challenging, and it urges combined contributions from multiple disciplines such as, kinematics, dynamics, control, machine learning and so on. Therefore, capabilities of artificial hands in general have been constrained to some specific tasks according to their target applications, such as grasping (in biomimetic hands) or speed/precision in a pick and place (in industrial grippers). Robotic grippers developed during last decades are mostly aimed to solve grasping complexities of several objects as their primary objective. However, due to the increasing demands of industries, many issues are rising and remain unsolved such as in-hand manipulation and placing object with appropriate posture. Operations like twisting, altering orientation of object within-hand, require significant dexterity of the gripper that must be achieved from a compact mechanical design at the first place. Along with manipulation, speed is also required in many robotic applications. Therefore, for the available speed and design simplicity, nonprehensile or dynamic manipulation is widely exploited. The nonprehensile approach however, does not focus on stable grasping in general. Also, nonprehensile or dynamic manipulation often exceeds robot’s kinematic workspace, which additionally urges installation of high speed feedback and robust control. Hence, these approaches are inapplicable especially when, the requirements are grasp oriented such as, precise posture change of a payload in-hand, placing payload afterward according to a strict final configuration. Also, addressing critical payload such as egg, contacts (between gripper and egg) cannot be broken completely during manipulation. Moreover, theoretical analysis, such as contact kinematics, grasp stability cannot predict the nonholonomic behaviors, and therefore, uncertainties are always present to restrict a maneuver, even though the gripper is capable of doing the task. From a technical point of view, in-hand manipulation or within-hand dexterity of a gripper significantly isolates grasping and manipulation skills from the dependencies on contact type, a priory knowledge of object model, configurations such as initial or final postures and also additional environmental constraints like disturbance, that may causes breaking of contacts between object and finger. Hence, the property (in-hand manipulation) is important for a gripper in order to obtain human hand skill. In this research, these problems (to obtain speed, flexibility to a plurality of grasps, within-hand dexterity in a single gripper) have been tackled in a novel way. A gripper platform named Dexclar (DEXterous reConfigurable moduLAR) has been developed in order to study in-hand manipulation, and a generic spherical payload has been considered at the first place. Dexclar is mechanism-centric and it exploits modularity and reconfigurability to the aim of achieving within-hand dexterity rather than utilizing soft materials. And hence, precision, speed are also achievable from the platform. The platform can perform several grasps (pinching, form closure, force closure) and address a very important issue of releasing payload with final posture/ configuration after manipulation. By exploiting 16 degrees of freedom (DoF), Dexclar is capable to provide 6 DoF motions to a generic spherical or ellipsoidal payload. And since a mechanism is reliable, repeatable once it has been properly synthesized, precision and speed are also obtainable from them. Hence Dexclar is an ideal starting point to study within-hand dexterity from kinematic point of view. As the final aim is to develop specific grippers (having the above capabilities) by exploiting Dexclar, a highly dexterous but simply constructed reconfigurable platform named VARO-fi (VARiable Orientable fingers with translation) is proposed, which can be used as an industrial end-effector, as well as an alternative of bio-inspired gripper in many robotic applications. The robust four fingered VARO-fi addresses grasp, in-hand manipulation and release (payload with desired configuration) of plurality of payloads, as demonstrated in this thesis. Last but not the least, several tools and end-effectors have been constructed to study prehensile and non-prehensile manipulation, thanks to Bayer Robotic challenge 2017, where the feasibility and their potentiality to use them in an industrial environment have been validated. The above mentioned research will enhance a new dimension for designing grippers with the properties of dexterity and flexibility at the same time, without explicit theoretical analysis, algorithms, as those are difficult to implement and sometime not feasible for real systems

Abstract:
AbstractTo hand over more than just pick & place tasks to an industrial collaborative robotic arm with a two-jaw gripper, the gripper must first be removed, and a new tool mounted. This tool change requires either human assistance or an expensive tool changer. The tools applied to the end-effector are often highly expensive and software system interfaces between different tools and robots are seldom available. Therefore, a holder was developed that allows the robot to pick up and operate a tool, such as an electric screwdriver, without having to demount the two-jaw gripper. Instead, the gripper’s functionality is used to activate and deactivate the tool fixed to the holder. This paper presents the state-of-the-art of the underlying problem as well as the development process including simulations, the patented design, and the low-cost production of the tool holder. This detachable, low-cost tool holder enables a flexibilization of human-robot processes in manufacturing.

Abstract:
AbstractTo generate suitable grasping positions between tessellated handling objects and specific planar grippers, we propose a 2D analytical approach which uses a polygon clipping algorithm to generate detailed information about the intersection between both objects. With the generated knowledge about the intersection we check whether its shape fits to the set criteria of the operator and represents a valid grasping position. Before the polygon clipping algorithm is applied, a preprocessing step is performed, where appropriate surfaces from the handling object and the gripper are extracted. After rotating all surfaces into a common plane, potential clipping positions are detected and the clipping is performed to get an accurate intersection detection. The validation shows comparable running times to a OBBTree algorithm (0.1 ms per grasping position) while increasing the stability of the results from 30 to 100% for the evaluated test objects.

Abstract:
In this paper, we propose the addition of passive hydraulic mechanisms to simple parallel robotic grippers for improving disturbance rejection while maintaining the low cost of an industry standard gripper design. Each adaptive jaw on our gripper consists of three parallel hydraulic cylinders that are connected to a common local reservoir. The resultant passive hydraulic system is fully encased in the finger and moves independently of the actuator that closes the fingers. Such a design eliminates the need to engineer a complex cable or linkage system to allow for finger adaptability as many underactuated grippers do. Specifically, hydraulic cylinders need only be selected and connected together. As with other underactuated devices, the unconstrained freedoms of this design allow the gripper to adapt to unknown objects instead of creating a custom gripper shape for each new object the robot needs to grasp. In this paper, we analyze the ability of this gripper to maximize contact points over various sized objects and object placements while creating immobilizing form closure grasps. We than tested these improvements on a physical robot and found that grasp performance increased by up to 30% over a gripper lacking underactuation.

Abstract:
This paper describes a general purpose gripper to be used into industrial manufacturing application. The gripper has been developed in the context of the AUTORECON project. It is based on a 2 degrees of freedom finger that is able to adapt itself to objects of various shape, size, material and weight. Thanks to its highly reconfigurable and adaptive capabilities, the gripper described here is an attempt to create a gripper suitable in industrial application to assemble compounds of several different workpieces using only one robot. The high dexterity and the wide range of possible uses of the gripper described here intends to explore a new approach to the design of industrial grippers to be used in factory automation. Moreover, the adaptive capabilities of this gripper make it suitable to grasp workpieces with complicated geometry or highly irregular shape, as it has been proved in performed automotive test rig described here.

Abstract:
Abstract Within industrial manufacturing most processing steps are accompanied by transporting and positioning of workpieces. The active interfaces between handling system and workpiece are industrial grippers, which often are driven by pneumatics, especially in small scale areas. On the way to higher energy efficiency and digital factories, companies are looking for new actuation technologies with more sensor integration and better efficiencies. Commonly used actuators like solenoids and electric engines are in many cases too heavy and large for direct integration into the gripping system. Due to their high energy density shape memory alloys (SMA) are suited to overcome those drawbacks of conventional actuators. Additionally, they feature self-sensing abilities that lead to sensor-less monitoring and control of the actuation system. Another drawback of conventional grippers is their design, which is based on moving parts with linear guides and bearings. These parts are prone to wear, especially in abrasive environments. This can be overcome by a compliant gripper design that is based on flexure hinges and thus dispenses with joints, bearings and guides. In the presented work, the development process of a functional prototype for a compliant gripper driven by a bistable SMA actuation unit for industrial applications is outlined. The focus lies on the development of the SMA actuator, while the first design approach for the compliant gripper mechanism with solid state joints is proposed. The result is a working gripper-prototype which is mainly made of 3D-printed parts. First results of validation experiments are discussed.

Abstract:
Abstract The use of soft robotic grippers is an alternative to conventional rigid body grippers in industrial applications specifically in the handling of carpets. This paper presents, a novel design of a 3D soft robotic gripper based on a simulation model and experimental prototype that can be used for carpet handling applications. In addition, the fabrication method of the pneumatic soft robotic gripper is introduced. The pneu-net actuator geometrical parameters are optimized such as the thickness of the chamber walls and the internal structure of the chambers resulting in significantly improved pressure handling capabilities. The simple pneu-net and the modified actuator are tested at two different pressure 55 and 110 kPa, to check the range of motion. A single actuator is calculated to lift a maximum of five kilograms, with several actuators included in the gripper the weight carrying capabilities reached ten kilograms. The geometry was optimized to maximize weight carrying capabilities by increasing the amount of pressure the actuator can withstand. A finite element analysis using ABAQUS software is carried out to evaluate the stresses acting upon the soft gripper.

Abstract:
Abstract Industrial manufacturing companies face the challenge of adapting to increasingly complex demands, especially with the influx of online ordering. One case of this is in the underperformance of end-effectors, limiting the adaptability of robotic arms in manufacturing functionality. To create proper gripper adaptability, intelligent gripper design is required to improve the sensibility and processing capability of the end-effectors. This will allow for grippers to perform effective decision-making and optimize production. This paper suggests a methodology that includes a step-by-step design process for an intelligent gripper and discusses how to develop intelligence utilizing key components of Industry 4.0 (Internet of Things, machine learning, and cloud manufacturing). This method was analyzed in a case study of a low-level intelligent vacuum gripper design. The methodology will be beneficial to intelligent gripper design from multiple levels of intelligence, creating a guide for engineers to follow to effectively design intelligent gripper solutions for their systems.

Abstract:
Dexterous gripper requirements, such as in-hand manipulation is a capability on which human hands are unique at; numerous number of sensors, degree of freedom, adaptability to deal with plurality of object of our hand motivate the researchers to replicate these abilities in robotic grippers. Developments of gripper or grasping devices have been addressed from many perspectives: the use of materials in the gripper synthesis, such as rigid or flexible, the approach of control, use of under-actuated mechanism and so on. Mathematical formulation of grasp modeling, manipulation are also addressed; however, due to the presence non-holonomic motion, it is difficult to replicate the behaviors (achieved in model) in a physical gripper. Also, achieving skills similar to human hand urge to use soft or non rigid material in the gripper design, which is contrary to speed and precision requirements in an industrial gripper. In this dilemma, this paper addresses the problem by developing modular finger approach. The modular finger is built by two well known mechanisms, and exploiting such modular finger in different numbers in a gripper arrangement can solve many rising issues of manipulation.

Abstract:
In-hand manipulation is a frequently demanded task which requires a significant dexterity from grippers. Operations such as object twisting, re-grasping and re-positioning with correct posture after manipulation are the major industrial challenges. Such requiring also determine design complexity of grippers. This paper proposes a new modular two DOF finger which is capable to do manipulation such as twist object about two independent axes when used in modular assembled configuration. Multiple identical fingers of such type can be used to build the gripper whose primary purposes are solving manipulation and after manipulation requirements such as regrasp and release object with appropriate posture. The fingers are implemented in the gripper by means of a properly conceived mechanism to ensure the mobility needed for grasping. In this research, the manipulation capabilities of the gripper developed by such identical fingers is investigated by the means of simulation in a multibody simulated environment. Moreover, a prototype of one finger has been built for preliminary inspection of the modular entity which represents the constructive base of the gripper concept object of this study.

Abstract:
In recent years, applications in industrial assemblies within a size range from 0.5mm to 100mm are increasing due to the large demands for digital multimedia products. Research on grippers or robotic hands within the mesoscopic scale of this range has not been well explored. This paper proposes a mesoscopic scale gripper (meso-gripper) which has two modes: passive adjusting mode and an angled precision gripping mode. The gripper adjusts its shape automatically according to the appropriate mode. This form of gripping and the associated mechanism are novel in their implementation and operation. The meso-gripper which has metamorphic characteristics is generated by integrating a remote center of motion (RCM) mechanism with a cross four-bar (CFB) linkage. The dimensional synthesis of the gripper is outlined for a specified task-based gripping followed by the analysis of the synthesizing mechanism. A differential mechanism is adopted to increase the flexibility of the meso-gripper. Prototype is fabricated and tested using 3D printing technology to verify the feasibility of the design.
