Abstract:
Flexible production is a key element in modern industrial manufacturing. Autonomous mobile manipulators can be used to execute various tasks: from logistics, to pick and place, or handling. Therefore, autonomous robotic systems can even increase the flexibility of existing production environments. However, the application of robotic systems is challenging due to their complexity and safety concerns. This paper addresses the design and implementation of the autonomous mobile manipulator OMNIVIL. A holonomic kinematic design provides high maneuverability and the implemented sensor setup with the underlying localization strategies are robust against typical static and dynamic uncertainties in industrial environments. For a safe and efficient human–robot collaboration (HRC), a novel workspace monitoring system (WMS) is developed to detect human co-workers and other objects in the workspace. The multilayer sensor setup and the parallel data analyzing capability provide superior accuracy and reliability. An intuitive zone-based navigation concept is implemented, based on the workspace monitoring system. Preventive behaviors are predefined for a conflict-free interaction with human co-workers. A workspace analyzing tool is implemented for adaptive manipulation, which significantly simplifies the determination of suitable platform positions for a manipulation task.

Abstract:
A new kinematic design of a parallel spherical wrist with actuator redundancy is presented. A special feature of this parallel manipulator is the arrangement of co-axial actuators which allows unlimited rotation about any axis inside a cone-shaped workspace. A detailed kinematic analysis has shown that actuator redundancy not only removes singularities but also increases workspace while improving dexterity. The structure optimization has been performed with a global dexterity criterion. Using a conditioning measure, a comparison with a non-redundant structure of the same type was performed and shows that a significant improvement in dexterity has been obtained.

Abstract:
The purpose of this research is to explore the relationship between gender and job satisfaction, as well as its factors. The case study was conducted among academic and administrative staff at a university environment, to identify factors contributing to job satisfaction and their importance for female and male employees. Overall, there were 102 returned questionnaires and 20 interviews with academic and administrative employees. The relationships between gender and job satisfaction factors were found for specific factors such as personal workspace and job security. T-tests identified statistical significance for differences in satisfaction with personal workspace, relationship with co-workers, and support for training and development factors. Besides, more females are concerned with flexibility at work than males.

Abstract:
Purpose Paediatric congenital esophageal atresia surgery typically requires delicate and dexterous operations in a narrow and confined workspace. This study aims to develop a novel robot assisted surgical system to address these challenges. Design/methodology/approach The proposed surgical robot consists of two symmetrical slave arms with nine degree of freedoms each. Each slave arm uses a rigid-dexterous configuration and consists of a coarse positioning manipulator and a distal fine operation manipulator. A small Selective Compliance Assembly Robot Arm (SCARA) mechanism was designed to form the main component of the coarse positioning unit, ensuring to endure large forces along the vertical direction and meet the operational demands. The fine positioning manipulator applied the novel design using flexible shafts and universal joints to achieve delicate operations while possessing a high rigidity. The corresponding kinematics has been derived and then was validated by a co-simulation that was performed based on the combined use of Adams and MATLAB with considering the real robot mass information. Experimental evaluations for the tip positioning accuracy and the ring transfer tasks have been performed. Findings The simulation was performed to verify the correctness of the derived inverse kinematics and demonstrated the robot’s flexibility. The experimental results illustrated that the end-effector can achieve a positioning accuracy within 1.5 mm in a confined 30 × 30 × 30 mm workspace. The ring transfer task demonstrated that the surgical robot is capable of providing a solution for dexterous tissue intervention in a narrow workspace for paediatric surgery. Originality/value A novel and compact surgical assist robot is developed to support delicate operations by using the dexterous slave arm. The slave arm consists of a SCARA mechanism to avoid experiencing overload in the vertical direction and a tool manipulator driven by flexible shafts and universal joints to provide high dexterity for operating in a narrow workspace.

Abstract:
This research explores how the open-plan office space in the Pikiran Rakyat Bandung head office influences the visual privacy preferences of the editorial staff. The aim is to find out what visual privacy is needed by the employees and the factors that might cause visual privacy disturbance on the employees of the open-plan office. The research observed several workstations with the potential of visual privacy disturbances, namely workstations that: a) is back-to-back with the walkway, b) is located at a walkway junction, c) is directly adjacent to the door, d) is adjacent to joint work facilities, e) is facing other coworkers, and f) is close to other co-workers on the right or left side. The research method was descriptive qualitative, using field observations and interviews to collect data. The result shows that: a) The interior settings of the workspace in open office space adjacent to coworkers both on the right side and left side are the most dominant factors that cause disruption to employees in visual privacy; b) Characteristics of employee’s task which need solitude condition influence visual privacy preferences the most, especially in the work layout (monitor). Thus, office space planning in an open office space at the Bandung People's Mind headquarters should consider the need for visual privacy by a) Rearranging the interior settings of the workspace with the ideal amount of workspace, b) Adding physical barriers between workspaces, and c) Arranging centralized shared work facilities for employees in open office space, hence minimalize disturbance from the conducted activities.

Abstract:
IntroductionSpace matters. We read space like we read people’s faces. Space is an instrument of collaboration and innovation. At the University of Michigan’s Institute for Clinical and Health Research (MICHR), a team was created to creatively and economically enhance our operating space into a flexible workspace that supports privacy, innovation, creativity, and most important, a culture of collaboration.MethodsThe team used a human-centered design process to creatively engage the staff at large into analyzing our existing space, identifying latent needs, proposing solutions, generating feedback, and economically building the rethought process.ResultsThe redesigned workspace embraces the differences among MICHR’s teams while encouraging collaboration and teamwork and keeping costs at a minimum. It has resulted in a flexible space that includes co-located teams, spaces dedicated to different work goals, an open area for collaboration, quiet zones for focused work, and better wayfinding.ConclusionsThrough our Rethink Space project, we hope to have demonstrated that, by initiating the project internally and by engaging the users of the space themselves in an empathetic, visual, and human-centered way, a space redesign can be undertaken economically while also leading to improved levels of employee and team satisfaction.

Abstract:
Human–robot collaboration poses many challenges where humans and robots work inside a shared workspace. Robots collaborating with humans indirectly bring difficulties for accomplishing co-carrying tasks. In our work, we focus on co-carrying an object by robots in cooperation with humans using visual and force sensing. A framework using visual and force sensing is proposed for human–robot co-carrying tasks, enabling robots to actively cooperate with humans and reduce human efforts. Visual sensing for perceiving human motion is involved in admittance-based force control, and a hybrid controller combining visual servoing with force feedback is proposed which generates refined robot motion. The proposed framework is validated by a co-carrying task in experiments. There exist two phases in experimental processes: in Phase 1 , the human hand holds one side of the box object, and the robot gripper of the Baxter robot automatically approaches to the other side of the box object and finally holds it; in Phase 2 , the human and the Baxter robot co-carry the box object over a distance to different target positions.

Abstract:
Technologies that support co-located collaboration must not only provide a shared workspace, but also support collaboration. From an observational study, some collaboration problems were identified in groups of people working in a system with a Tangible User Interface. Some of these problems could be identified and prevented with the support of Coaching System. This system encourages interactions between group members through Social Interventions. To develop a Coaching System, it is necessary to know the cohesion between the members of the group, in order to decide the appropriate Social Interventions. In this paper, a model is proposed to represent the social interactions that occur in a group of people when performing a task. Interactions can be analyzed to determine the degree of cohesiveness of a group and support the collaboration.

Abstract:
AbstractAlong with the increasing popularity of agile software development, software work has become much more social than ever. Contemporary software teams rely on a variety of collaborative practices, such as pair programming, the topic of our study. Many agilists advocated the importance of collocation, face-to-face interaction, and physical artefacts incorporated in the shared workspace, which the COVID-19 pandemic made unavailable; most software companies around the world were forced to send their engineers to work from home. As software projects and teams overnight turned into distributed collaborations, we question what happened to the pair programming practice in the work-from-home mode. This paper reports on a longitudinal study of remote pair programming in two companies. We conducted 38 interviews with 30 engineers from Norway, Sweden, and the USA, and used the results of a survey in one of the case companies. Our study is unique as we collected the data longitudinally in April/May 2020, Sep/Oct 2020, and Jan/Feb 2021. We found that pair programming has decreased and some interviewees report not pairing at all for almost a full year. The experiences of those who paired vary from actively co-editing the code by using special tools to more passively co-reading and discussing the code and solutions by sharing the screen. Finally, we found that the interest in and the use of PP over time, since the first months of the forced work from home to early 2021, has admittedly increased, also as a social practice.

Abstract:
This chapter itemizes and elaborates on four different component parts (described in the book as "ingredients") that make-up presidential foodways. The first ingredient relates to the president: his or her palate, food philosophy, schedule, wealth and prerogative. The second ingredient involves the people who surround the president: the First Lady, the president's physician, and those who procure food for the White House. The third ingredient is White House culture: the workspace, kitchen equipment and technology, co-workers, perks, presidential pets, wildlife in and outside of the White House and racial attitudes. The fourth ingredient is the unexpected influences: the U.S. Congress, public perception, food gifts from the public, and the climate in Washington, D.C. The chapter includes recipes for roast ducks, popovers (a quick bread), and sweet potato cheesecake.

Abstract:
Abstract Jobs performed by small to medium enterprises (SMEs) are infrequently automated due to high setup costs and lack of technical expertise needed for robot training, however productivity and worker safety can be improved in SMEs with the use automated tooling. In a traditional automated manufacturing environment, tasks such a welding or painting are accomplished through execution of pre-programmed tool motions which rely on the location and orientation of the workpiece to be fixed and known. The lack of this spatial information is typically treated through positioning of the workpiece with respect to the robot arm using jigs or fixtures which are costly in initial setup and not easily modified. Further, the resulting toolpath associated with a desired task is typically defined through manual teaching resulting in a path appropriate for an individual job. For this reason, SMEs requiring variation in part geometry or arrangement are not commonly automated. This work presents a method for automated weld path generation for a 6DOF co-bot arm using random sample consensus (RANSAC) and iterative closest point (ICP) workpiece localization from LiDAR point clouds. Scans from a low cost 2D LiDAR mounted to the co-bot arm are used to generate 3D point clouds of the workspace scene with the Robot Operating System (ROS). The Point Cloud Library (PCL) is used to compare the generated point cloud with a CAD model to produce a rigid transformation to localize the workpiece. The estimated pose of the workpiece with respect to a fixed frame is used offline to generate a weld path as series of tool poses. An example welding processes in which two square tubes are joined through weldment are investigated and a physical implementation of the method is demonstrated using a 2D LiDAR mounted to a 6DOF co-bot arm.

Abstract:
Assisted motor therapies play a critical role in enhancing the functional musculoskeletal recovery and neurological rehabilitation. Our focus here is to assist the performance of repetitive motor-therapy of the human lower limbs — in both the sagittal and frontal planes. Hence, in this paper, we develop a lightweight, reconfigurable hybrid (articulated-multibody and cable) based robotic rehabilitative device as a surrogate for a human physiotherapists and analyze feasibility and performance. A hybrid cable-actuated articulated multibody system is formed when multiple cables are attached from a ground-frame to various locations on the lower limbs. The combined system now features multiple holonomic cable-loop-closure constraints acting on a tree-structured multibody system. Hence the paper initially focuses on developing the Newton-Euler dynamic equilibrium equations of the cable-driven lower limbs to develop a symbolic analysis framework. The desired motion for the proposed rehabilitative exercise are prescribed based upon normative subjects motion patterns. Trajectory-tracking within this system is realized by a position-based impedance controller in task-space and a feedback-linearized PD controllers in joint-space. Careful coordination of the multiple cable-motors are now necessary in order to achieve the co-robotic control of the overall system, avoiding development of internal stresses and ensuring continued satisfaction of the unilateral cable-tension constraints throughout the workspace. This is now evaluated via a simulation case-study and development of a physical testbed is underway.
