A force detector includes a support, fluid bags, a contact portion, a detector, and a computer. The contact portion is opposite to a side on which the fluid bags are in contact with the support and is adjacent to the fluid bags. The computer obtains information regarding the internal pressures of the fluid bags from the detector. Upon application of an external force to the contact portion from an object, the computer calculates a force acting in a tangential direction on a contact surface between the object and the contact portion based on a difference between the internal pressures of the fluid bags.

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.
