    摘要: A technique allows a robot gripping one of two objects to perform appropriate surface alignment between the two objects. A control apparatus for a robot includes a virtual sensor associated with a force sensor and set on a control plane for predetermined control to control a position of a first object relative to a second object by causing a first surface of the first object gripped by a gripper to abut on a second surface of the second object, and a controller that performs the predetermined control based on a detection result from the virtual sensor using a control point set on the control plane based on a state of the first object being gripped by the gripper. The virtual sensor is projected on an imaginary line at a projection position between a predetermined contact point and the control point in an extending direction of the imaginary line on the control plane connecting the control point and the predetermined contact point being a contact point between the two objects and set on the control plane to place the first object into contact with the second object before the first surface abuts on the second surface in the predetermined control.

    摘要: There is provided a controller for fitting a first workpiece and a second workpiece to each other using a robot. The robot has a gripping mechanism for gripping the first workpiece, and a force sensor. The controller causes the robot to perform an operation of pressing the first workpiece against the second workpiece with a predetermined force, and an operation of changing a posture of the first workpiece with respect to the second workpiece in a state where the first workpiece is pressed against the second workpiece. The controller searches for the posture of the first workpiece in which a first surface of the first workpiece to be in contact with the second workpiece and a second surface of the second workpiece to be in contact with the first workpiece are parallel to each other, based on an evaluation index related to a distance between the first workpiece and the second workpiece.
