“…The system, designed in accordance with relevant norms and safety standards, allows the design of fenceless robotic cells. Augustsson et al [14] presented a work using a safetyEYE to define flexible safety zones in shared working environments, reducing the robot speed and maintaining a safe distance to the human operator during the robot carries out nailing routines. Even so there are some drawbacks in the safetyEYE as this system only provides discrete information about the state of the robotic cell (safe, warning or alarm) and it cannot 1 http://www.xact-project.eu/.…”

“…This type of cooperation has been tested in industry and works quite well, the problem lies in too much idle time for the robot. To try to avoid idle time and to create a situation where the human and robot can coproduce products and not just co-exist in the cell we have suggested in [3] a flexible zone system with adjustable safety zones with the ability to activate and deactivate zone arrangements in a dynamic way. The safety zones can also be grouped and assigned with different severity levels to control the interaction.…”

Flexible human-robot industrial coproduction will be important in many small and middle-sized companies in the future. One of the major challenges in a flexible robot cell is how to transfer information between the human and the robot with help of existing and safety approved equipment. In this paper a case study will be presented where the first half focus on data transfer to the robot communicating the human's position and movements forcing the robot to respond to the triggers. The second half focuses on how to visualize information about the settings and assembly order to the human. The outcome was successful and flexible, efficient coproduction could be achieved but also a number of new challenges were found.

“…In this case, however, the safety is a great concern. Several approaches has been studied including a 3D camera, Pilz SafetyEye [19]. However, it has been found feasible to use different approaches in combinations based on the specific design and need for the work process and robot system, and a combination of camera based techniques which include sectioning using laser scanners, and hand held devices which activate the collaborating robot has been tried out.…”

This paper presents a concept for reconfigurable and flexible robot systems. To reach a technology readiness level where solutions and results can be implemented in industry, the focus in this work is on systems with limited number of robots, and work scenarios which are reasonable complex but hard to automate using standard solutions.Four distinct areas have been identified as important within the concept and further studies: (i) human machine interaction, (ii) safety including collaboration, (iii) programming and deployment, and (iv) planning and scheduling. Feasibility studies have been made which addressed issues (ii) and (iii), in scenarios with collaboration between robot and human, or between two robots. For the chosen work scenario, manufacturing of structures in wood for family houses, challenges related to programming and safety was identified and possible solutions outlined.The concept and the studies indicate that feasible solutions can be found and designed given a reasonable consistent work processes and products. In this study, the processes are similar, nailing and screwing but different sizes may apply, the material is similar but variations may apply, and the construction is different of each product, but include the same type of operations at different locations. Our study confirm that human collaboration improves the ability to implement and use robots as it make it possible to move some operations to the human which otherwise would add to the complexity of the system. Furthermore, programming can also I general be simplified although methods for automatic programming has been tried out. But in some cases, the solution space is limited and the ability to move certain operations to a human simplifies the programming task. However, further work needs to be done in this area specifically related to safety issues for safe collaboration.
