    摘要: A system for judging success or failure of a work of a robot includes a position command generating unit, a contact position detecting unit, and a work success/failure judging unit. The position command generating unit generates a position command enabling movement of a fingertip of the robot so that a position and posture detecting unit, which is attached to the fingertip of the robot and has an elastic transformation area, is brought into contact with a predetermined position relating to a work target after the predetermined work is performed for the work target by the robot. The contact position detecting unit calculates a contact position that is a position of a tip end of the position and posture detecting unit at the time of being in contact with the predetermined position based on a value of an external force applied to the fingertip and the position of the tip end of the position and posture detecting unit. The work success/failure judging unit judges the predetermined work to be successful when the calculated contact position is within a predetermined range and judges the predetermined work to be failed when the calculated contact position is not within the predetermined range.

    摘要: A control apparatus and compliance control apparatus of a robot which performs operations while switching between a position control and a compliance control. When a transition from the position control to the compliance control is made, an integration operation of a speed control system is stopped. Thereafter, an integration value of the speed control system is stored in a memory, and, at the same time, the integration value is added to a torque reference. Alternately, a gravity compensation value is added to the torque reference, the gravity compensation value being computed based on a joint angle of a robot arm and a link mass and a position of a center of gravity of the robot. When the control returns from the compliance control to the position control, a present position is dealt with an instruction position. The compliance control apparatus includes a device (102) for controlling a torque of a servo motor to drive a joint portion; a device (106) for measuring a joint angle; a device (108) for computing a very small displacement between coordinates based on the measurement information; a device (102) for converting a limitation value (107) of either a force or a torque set in a working coordinate system by giving the foregoing very small displacement correspondence relation to the foregoing computation means (108); and devices (104, 105, 106) for limiting the torque.
