Abstract
A manipulator having a grasping mechanism for grasping an object and an arm mechanism for lifting the grasped object, is disclosed. A weight detector is provided which detects a force that the top of the arm mechanism receives in the gravitational direction when the grasped object is being lifted. In order to find the minimum grasping force sufficient to lift the object, a grasp detector is provided for detecting, from the output of the weight detector, that the object cannot be lifted up with the present grasping force and a desired grasping force selector for selecting successively a desired value of grasping force starting from a predetermined minimum desired value until it is detected that the object is lifted. A grasping force control circuit controls the grasping force to the selected desired value.
