Patent number: 8600552Abstract: An apparatus executes movement control that causes a robot arm equipped with a camera to move up to an object, thereby enabling a manipulator to move to an object quickly, accurately, and stably as a control system. Specifically, when the object is not detected, the apparatus executes teaching playback control to cause a manipulator to move along a path up to a target position set in advance based on a position of the object. When the object is detected, the apparatus defines a position closer to the object than the target position as a new target position, sets a new path up to the new target position, executes teaching playback control to cause the manipulator to move along the new path until a switching condition for switching the movement control is fulfilled. When the switching condition is fulfilled, the apparatus executes visual servo control.Type: GrantFiled: October 27, 2010Date of Patent: December 3, 2013Assignee: Honda Motor Co., Ltd.Inventors: Ryo Nakajima, Hideari Kamachi, Gentoku Fujii
