Abstract
A method includes a measurement step of producing measured force information of external force by causing a robot to perform an action using second servo gains adjusting force control parameters corresponding to first servo gains when the robot performs a regular task. The measured force information includes an action period of time during which the action is performed, a maximum detected force value of the external force, and a maximum detected torque value of the external force. The method further includes a parameter update step of producing a new candidate value of the force control parameters by carrying out an optimization process on the force control parameters by using the measured force information. The method further includes a parameter determination step of determining the force control parameters used in the force control performed by the robot by repeating the measurement step and the parameter update step.
