Abstract
A robot control device able to accurately estimate an external force applied from a workpiece to a robot in a time-dependently changing manner. The robot control device includes a support force data acquisition section which acquires measurement data of a workpiece support force by the environment, the workpiece support force varying while the robot lifts the workpiece; a disturbance estimation section which estimates a disturbance value applied to the robot using state information of the robot; and a correction section which corrects, using the measurement data acquired by the support force data acquisition section, the disturbance value estimated by the disturbance estimation section or the state information inputted to the disturbance estimation section.
