| Research Abstract |
For motion control of a robot arm, singular configurations of the arm tend to be avoided. In this study, we showed that, when a certain kind of tasks are performed by a robot arm, the joint torques necessary to achieve the tasks can be reduced by using singular configurations.
The optimal motion for achieving the tasks was obtained by numerical optimization, and the dynamic features of singular configurations were revealed by analyzing the obtained motion. The experiments for an actual robot arm to achieve the obtained motion were performed to show that the advantage of singular configurations in reducing the joint torques is practically useful.
