Patent number: 9616573Abstract: An end effector can be removed to a target position and calibration loads can be reduced, even if there is an error in a kinematic operation in a robot main body and/or cameras. A positional deviation integral torque obtained by integrating a value corresponding to a positional deviation is applied to joints while being superimposed with torques based on angular deviations. If movements of the joints stop or are about to stop before the end effector reaches a target position due to an error in a kinematic operation, the positional deviation integral torque increases with time, to move said joints and move the end effector to the target position. Thus, the end effector can be reliably moved to the target position by the positional deviation integral torque, and calibration loads can be reduced.Type: GrantFiled: May 23, 2013Date of Patent: April 11, 2017Assignee: THE RITSUMEIKAN TRUSTInventors: Sadao Kawamura, Hiroyuki Onishi
