This category handles special-purpose industrial robots other than vertical articulated robots, horizontal articulated robots, Cartesian robots, and parallel link robots. It includes industrial robots with special mechanisms or applications such as collaborative robots (cobots), mobile robots (AGV/AMR), dual-arm robots, redundant degree-of-freedom robots, cable-driven robots, and pneumatic-driven robots. This product group addresses special requirements that are difficult for conventional industrial robots to handle, including collaborative work with humans, autonomous movement in complex work environments, high-precision assembly work, and operations in confined spaces.
