Résumé :

2014 - 2015<br>The manufacturing industry is very diverse and covers a wide range of specific processes ranging from extracting minerals to assembly of very complex products such as planes or computers, with all intermediate processing steps in a long chain of industrial suppliers and customers. It is well know that the introduction of robots in manufacturing industries has many advantages. Basically, in relation to human labor, robots work to a constant level of quality. For example, waste, scrap and rework are minimized. Furthermore they can work in areas that are hazardous or unpleasant to humans. Robots are advantageous where strength is required, and in many applications they are also faster than humans. Also, in relation to special-purpose dedicated equipment, robots are more easily reprogrammed to cope with new products or changes in the design of existing ones. In the last 30-40 years, large enterprises in high-volume markets have managed to remain competitive and maintain qualified jobs by increasing their productivity with the incremental adoption and use of advanced ICT and robotics technologies. In the 70s, robots have been introduced for the automation of a wide spectrum of tasks such as: assembly of cars, white goods, electronic devices, machining of metal and plastic parts, and handling of workpieces and objects of all kinds. Robotics has thus soon become a synonym for competitive manufacturing and a key contributing technology for strengthening the economic base of Europe . So far, the automotive and electronics industries and their supply chains are the main users of robot systems and are accounting for more than 60% of the total annual robot sales. Robotic technologies have thus mainly been driven by the needs of these high-volume market industries. The degree of automation in the automotive industries is expected to increase in the future as robots will push the limits towards flexibility regarding faster change-over-times of different product types (through rapid programming generation schemes), capabilities to deal with tolerances (through an extensive use of sensors) and costs (by reducing customized work-cell installations and reuse of manufacturing equipment). There are numerous new fields of applications in which robot technology is not widespread today due to its lack of flexibility and high costs involved when dealing with varying lot sizes and variable product geometries. In such cases, hyper-flexible robotic work cells can help in providing flexibility to the system and making it adaptable to the different dynamic production requirements. Hyper-flexible robotic work cells, in fact, can be composed of sets of industrial robotic manipulators that cooperate to achieve the production step that characterize the work cell; they can be programmed and re-programmed to achieve a wide class of operations and they may result versatile to perform different kind of tasks Related key technology challenges for pursuing successful long-term industrial robot automation are introduced at three levels: basic technologies, robot components and systems integration. On a systems integration level, the main challenges lie in the development of methods and tools for instructing and synchronising the operation of a group of cooperative robots at the shop-floor. Furthermore, the development of the concept of hyper flexible manufacturing systems implies soon the availability of: consistent middleware for automation modules to seamlessly connect robots, peripheral devices and industrial IT systems without reprogramming everything (”plug-and-play”) . In this thesis both innovative and traditional industrial robot applications will be analyzed from the point of view of task coordination. In the modeling environment, contribution of this dissertation consists in presenting a new methodology to obtain a model oriented to the control the sequencing of the activities of a robotic hyperflexible cell. First a formal model using the Colored Modified Hybrid Petri Nets (CMHPN) is presented. An algorithm is provided to obtain an automatic synthesis of the CMHPN of a robotic cell with detail attention to aircraft industry. It is important to notice that the CMHPN is used to model the cell behaviour at a high level of abstraction. It models the activities of each cell component and its coordination by a supervisory system. As more, an object oriented approach and supervisory control are proposed to implement industrial automation control systems (based on Programmable Logic Controllers) to meet the new challenges of this field capability to implement applications involving widely distributed devices and high reuse of software components. Hence a method is proposed to implement both controllers and supervisors designed by Petri Nets on Programmable Logic Controllers (PLCs) using Object Oriented Programming (OOP). Finally preliminary results about a novel cyber-physical approach to the design of automated warehouse systems is presented. [edited by author]<br>XIV n.s.

Résumé :

Industrial robots are both versatile and high performant, enabling the flexible automation typical of the modern Smart Factories. For safety reasons, however, they must be relegated inside closed fences and/or virtual safety barriers, to keep them strictly separated from human operators. This can be a limitation in some scenarios in which it is useful to combine the human cognitive skill with the accuracy and repeatability of a robot, or simply to allow a safe coexistence in a shared workspace. Collaborative robots (cobots), on the other hand, are intrinsically limited in speed and power in order to share workspace and tasks with human operators, and feature the very intuitive hand guiding programming method. Cobots, however, cannot compete with industrial robots in terms of performance, and are thus useful only in a limited niche, where they can actually bring an improvement in productivity and/or in the quality of the work thanks to their synergy with human operators. The limitations of both the pure industrial and the collaborative paradigms can be overcome by combining industrial robots with artificial vision. In particular, vision can be exploited for a real-time adjustment of the pre-programmed task-based robot trajectory, by means of the visual tracking of dynamic obstacles (e.g. human operators). This strategy allows the robot to modify its motion only when necessary, thus maintain a high level of productivity but at the same time increasing its versatility. Other than that, vision offers the possibility of more intuitive programming paradigms for the industrial robots as well, such as the programming by demonstration paradigm. These possibilities offered by artificial vision enable, as a matter of fact, an efficacious and promising way of achieving human-robot collaboration, which has the advantage of overcoming the limitations of both the previous paradigms yet keeping their strengths.

Résumé :

This thesis presents a flexible arrangement of robots used for two point continuity tests. Robots are used increasingly in the manufacturing industry because of their flexibility. In the electronics packaging industry, there are many instances where one wants to do a two point continuity test. These two points can be anywhere on a given card. This application is the perfect candidate for a robotic implementation using two robots. However, challenges involve designing an appropriate workcell and figuring out how to have the two robots work together. Both of these problems were addressed in this research project. The thesis begins by exposing the initial environment and then it outlines an enhanced solution that was adopted for both the workcell design and the motion planning. Some test results for the motion planner are then presented. A workcell such as the one presented here has actually been developed and is currently being used in some manufacturing operations.

Résumé :

For many years robots have been programmed at manipulator or joint level without any real thought to the implementation of sensing until errors occur during program execution. For the control of complex, or multiple robot workcells, programming must be carried out at a higher level, taking into account the possibility of error occurrence. This requires the integration of decision information based on sensory data. Aspects of robotic workcell control are explored during this work with the object of integrating the results of sensor outputs to facilitate error recovery for the purposes of achieving completely autonomous operation. Network theory is used for the development of analysis techniques based on stochastic data. Object level programming is implemented using Markov chain theory to provide fully sensor integrated robot workcell control.

Résumé :

Programming a robotic workcell involves much more than simply writing a program for each element, because the operations to be performed are tightly coupled by precedence constraints on their time ordering, and by constraints associated with the shared resources. The situation is further complicated because robotic workcells are typically configured to repetitively perform a desired application; we would therefore like to optimize the order in which operations take place, so as to minimize the total time required. But even when the operations have deterministic outcomes, there may exist alternative sequences with different durations, due to non-determinism in the workcell sequencing problem itself. In this dissertation, we introduce a classification of sequencing problems according to the presence of non-determinism. We then develop a particular model of workcell behavior called the Constraints Net, based on the Timed Petri Net of Ramchandani. Some new results are presented about the relationship between repetitive runtime behavior and the strong connectivity of the CN. We then define strong reducibility as the graph-theoretic property associated with modelling conflict in a meaningful way. Existing descriptions of repetitive behavior in the Petri Net literature are unified and extended. We conclude with a description of a Prolog-based decision support system called SAGE (Sequence Analysis by Graphical Evaluation) which resolves non-determinism in the user description by exploring the consequences of alternate orderings of workcell operations, and ultimately constructs the time-optimal sequence to be used by the workcell runtime environment. The analysis and optimization is illustrated with an example implemented in our laboratory.

Résumé :

The complexity of modern robotic workcells, consisting of many cooperating elements (eg. robots, sensing systems) makes programming applications enormously difficult. Programming such a complex robotic system is a complicated task that requires thorough understanding of each of its elements. Thus far, little has been done in the way of developing a robotic workcell programming environment: this dissertation addresses this very problem. A hierarchical framework is proposed that decomposes the problem into three sub-problems, (i) the Planning sub-problem, addressed by the Strategy level, which determines what has to be done in terms of 'steps' that have to be performed, decides which active element will perform each of those 'steps' and determines the layout of the workcell, (ii) the Coordination sub-problem, addressed by the Tactics level which determines when a 'step' can be executed, and (iii) the Command sub-problem, addressed by the Virtual Device level, which determines how each of the 'steps' is executed. In particular, we will focus on the Coordination and Command sub-problems addressed by the run-time control environment. We will define a state formalism and based on it we will build a model of the intended workcell behavior. A prototype implementation of the proposed run-time control and programming environment, called WRAP (Workcell ReAl-time Programming) is described. An idealized assembly task was programmed to evaluate the approach and an evaluation of these experimental results is presented.

Résumé :

A robotic workcell is a collection of robots, sensors, and other industrial equipment grouped in a cooperative environment to perform various complex tasks. Due to their distributed nature however, the control and programming of robotic workcells is often a difficult task, for which dedicated environments have to be designed and built.<br>Simulation, especially graphic simulation, can greatly contribute to the development of programs for such integrated robotic applications: the simulator emulates the behavior of the workcell on a computer display, and allows the programmer to test and debug programs without requiring an immediate access to the physical equipment.<br>This thesis presents the design of a graphic simulator for robotic workcell applications. The simulator is based on SAGE/WRAP, an environment for the programming and run-time control of robotic workcells. Given a WRAP program as input, the simulator displays a top-view of the workcell and animates graphically the execution of the program; the coordination and the flow of operations within the workcell being shown, the programmer can quickly assess the overall validity of the program.<br>The simulator was developed in C under the X Window System, and is currently implemented as a standalone software; the design was made flexible and modular, to facilitate an eventual integration to the WRAP environment.

This work follows the design, prototyping and implementation of an automatic part loading and unloading system for use in thread rolling of aerospace fasteners. The thread rolling automation system is designed to function as part of a multi-process workcell, which emphasizes adaptability and ease of implementation. Design of the thread rolling automation facilitates the development of a universal gripping system, which is designed to grasp a large variety of fastener styles and sizes with a minimum of tooling changeover. A novel grasping model is developed to predict the error tolerance of the proposed gripping system design, which is validated experimentally. The proposed gripper and automation system are prototyped and tested, and shown to perform reliably with a wide range of fastener types.

Résumé :

In this research we develop an integrated approach to optimally sequence robot operation in a workcell. The workcell represents a f1owshop operation with multiple robots transporting jobs among machines. A buffer of infinite capacity is available ahead of each machine. A robot transports jobs from buffers to machines and from machines to buffers. The robots used in the system are 5 jOint cylindrical coordinate robots. All the robots are identical in design and capability. For the type of robot used in this study its closed form inverse kinematic solution is known. The objective is to determine the sequence of robot operations so as to minimize the total time needed to complete all jobs (known as makespan). <p> The integrated approach consists of determining optimal robot task sequences using a branch and bound procedure. and a graphical simulation procedure to display the robots as they perform transport operation. The branch and bound algorithm, which is an implicit enumeration scheme, is used to derive several near optimal robot task sequences. For the branch and bound algorithm. each node is a transport operation. Lower bound on the makespan is machine based and is computed at each node for further branching. The graphical simulation is used to detect interference among robots which is hard to be incorporated in the branch and bound procedure. Infeasible robot sequences are discarded and other solutions from the branch and bound procedure are displayed using the graphical simulation procedure to determine a near optimal and feasible sequence. <p> The integrated approach is implemented on a prototype system. A command driven general purpose graphics system MOVIE.BYU is used for the graphical simulation of the robotic workcell and robot motion. The entire system is available in an integrated environment. A powerful programming language Rexx is used to manage various programs and data. Also, intermediate Rexx programs are generated during execution to allow MOVIE.BYU to edit and display animation data on the Tektronix 41XX series of terminals. The entire system is flexible and modular to be able to be used for various different applications.<br>Master of Science

Résumé :

This master's thesis focuses on the use of the Renishaw's Equator gauging system in cooperation with the industrial robot. The target is to design the robotized workcell which contains these two products. Robot acts as a manipulator for inserting and sorting out the workpieces into the "good" and "bad" pallets according to measured results from the Equator. Equator uses a parallel kinematics and probing system which is normally used on coordinate measuring machines. Therefore there is the introduction to the parallel and serial kinematic structures, to the problems of the coordinate measuring machines in the first part of this thesis. It was made a separation of the probing systems into a few basic categories, description of the typical representatives of these categories and of the other important accessories of the coordinate measuring machines, too. The second part of the thesis contains a description of the Equator gauging system, the industrial robot which I used and their accessories. In this part is mentioned a few examples of measurement automation in industry practice, too. The third part devotes to the design of the robotized workcell and contains all the important requirements for the realization.

Résumé :

The design of manufacturing systems in hazardous environments is complex, requiring interdisciplinary knowledge to determine which components and operators (human or robotic) are feasible. When conceptualizing designs, some options may be overlooked or unknowingly infeasible due to the design engineers' lack of knowledge in a particular field or ineffective communication of requirements between disciplines. To alleviate many of these design issues, we develop a computational design tool to automate the synthesis of conceptual manufacturing system designs and optimization of preliminary layouts. To generate workcell concepts for manufacturing processes, we create a knowledge-based system (KBS) that performs functional modeling using a common language, a generic component database, and a rule set. The KBS produces high-level task plans for specific manufacturing processes and allocates needed material handling tasks between compatible human and/or robotic labor. We develop an extended pattern search (EPS) algorithm to optimize system layouts based on worker dose and cycle time minimization using the functions and sequencing of generated task plans. The KBS and EPS algorithm were applied to the design of glovebox processing systems at Los Alamos National Laboratory (LANL). Our computational design tool successfully generates design concepts with varied task allocation and processing sub-tasks and layouts with favorable manipulation workspaces. This work establishes a framework for automated conceptual design while providing designers with a beneficial tool for designing manufacturing systems in an interdisciplinary and highly constrained domain.<br>text

Based on CTPN, the dynamic behaviors of the furnace, such as loading, processing, unloading and wafer count mismatching, can be emulated the CTPN model is hierarchical and modular. The hierarchical architecture is built by dividing the behaviors of the furnace to make the model more compact and the modular modeling make the model flexible and easy use.In addition to modeling and analysis, the monitoring of the furnace system is designed and accomplished. The furnace emulator provides a quasi environment for upper level system testing. In addition, it facilitates the design of the group controller without using true equipment. Finally, the workcell concept is merged into the furnace system.

Résumé :

This thesis deals with the development of an automated robotic deburring workcell for refurbished components with intricate geometry. Deburring of a refurbished workpiece involves establishing the location of the workpiece, establishing its geometry using surface digitizing and mathematical splining algorithms, extrapolating the reconstructed surface to get the edge profile, determining and executing the tool path. The robot chosen for the workcell is YAMAHA Zeta-1 robot designed specifically for deburring. A displacement sensor with an accuracy of 0.004 mm is interfaced to the workcell. The limited computational ability of the robot controller and its closed architecture have necessitated the development of an external controller to coordinate the activities of the workcell. The robot controller neither provides for communication with external computing systems, nor does it allow interfacing external sensors.

Résumé :

This article describes the development of a component-based technology robot system that can be rapidly configured to perform a specific manufacturing task. The system is conceived with standard and inter-operable components including actuator modules, rigid link connectors and tools that can be assembled into robots with arbitrary geometry and degrees of freedom. The reconfigurable "plug-and-play" robot kinematic and dynamic modeling algorithms are developed. These algorithms are the basis for the control and simulation of reconfigurable robots. The concept of robot configuration optimization is introduced for the effective use of the rapidly reconfigurable robots. Control and communications of the workcell components are facilitated by a workcell-wide TCP/IP network and device level CAN-bus networks. An object-oriented simulation and visualization software for the reconfigurable robot is developed based on Windows NT. Prototypes of the robot systems configured to perform 3D contour following task and the positioning task are constructed and demonstrated. Applications of such systems for biomedical tissue scaffold fabrication are considered.<br>Singapore-MIT Alliance (SMA)

Résumé :

This thesis details a research project into the viability of increasing the level of automation employed in the canning of salmon. Specifically the post-filling quality control patching table has been studied. Data on this system was compiled from survey, interviews, and video tape of quality control personnel, and from a series of experiments done in an industry plant during a canning operation. The patching table workcell has been modelled and simulated using a computer simulation package. Several automation implementations are explored for their effectiveness and physical realizability. The most promising of these options have been simulated and evaluated for their economic profitability. Recommendations to the industrial producers are then presented.
