Abstract: A control system for a manipulator capable of controlling the movement of a manipulator in such a manner that, when bringing an object grasped by the manipulator into physical contact with a nearby object, the grasped object comes into contact with the nearby object with an appropriate contact force are provided. The control system for a manipulator includes an arm, and a hand attached to the arm and configured to grasp an object to be grasped. The control system includes an environment recognition unit configured to recognize a nearby object in an environment around the manipulator, an arm control unit configured to control a movement of the arm, and a hand control unit configured to predict a contact state between the grasped object and the nearby object, and adjust a grasping force of the hand according to the prediction of the contact state.

Abstract: A torque estimation method according to the present disclosure estimates a value of shaft torque of a rotary motion transmitting mechanism. The torque estimation method includes: a step of specifying a maximum value of a torsion angle between an input shaft and an output shaft from the time when a measurement value of the torsion angle is zero to the time when the value of the shaft torque is estimated; and a step of specifying the maximum value of the torsion angle. In the step of specifying the maximum value of the torsion angle, the maximum value of the torsion angle is specified based on a difference between the measurement value of the torsion angle subjected to low-pass filter processing at a first cutoff frequency and the measurement value of the torsion angle subjected to low-pass filter processing at a second cutoff frequency.

Abstract: An external force estimation device is configured to estimate an external force acting on a motor. The external force estimation device includes a processor. The processor is configured to: calculate an output torque of the motor by using a value of a current supplied to the motor; estimate an inertia torque of the motor by using rotational position information of the motor; estimate a first friction torque of the motor by using the rotational position information of the motor; perform temperature-based correction for the first friction torque by using temperature information of the motor; and estimate the external force by subtracting the inertia torque and the first friction torque after the temperature-based correction from the output torque.
