Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
1 . A robot control apparatus that controls a robot configured to include a freely displaceable joint and move an end effector according to a displacement of the joint, comprising: an imager to image a reference position provided on the robot while capturing the reference position and a destination of the reference position in a field of view; a displacement amount detector to detect a displacement amount of the joint; a positional deviation acquirer to acquire a positional deviation from t…
