Catching a small object in high-speed motion
So far, we proposed the passive joint between hand and tools in order to achieve more skillful tool-handling. The high-speed robot system we developed has the potential of achieving the task and tool-handling which human cannot do, because it can behave faster and get information from the external world faster than human by high-speed actuator and high-speed vision system. In this research, we aim for finding out new skill in tool-handling which uses high-speed performance maximally.
For instance of task overcoming human, we achieved catching 6mm plastic ball in parabolic motion using tweezers. In this task, the margin for error between the center of tweezers and ball is plus or minus 1.5mm. So precise handling is needed.
