Abstract
There is provided a control apparatus and control method for robot arm, robot, control program for robot arm, and integrated electronic circuit, which can improve robot arm operability upon performing tasks such as cooperative conveyance and direct teaching. The grip portion separated from the end effector attached to the robot arm is provided. When a person grips and shifts the grip portion, a tracking control unit controls so that the robot arm follows the shift. A fixing switch unit switches between a fixing state where, upon switching to “playback mode”, a fixing portion is located at a fixed position to fix the end effector and the grip portion to maintain a gap distance therebetween and a relatively shiftable state where, upon switching to “teaching mode”, the fixing portion is located at an accommodated position to relatively shift them from each other without maintaining the gap distance.
