<p>There is described a manipulator (100) of which an arm (4) can be moved by means of an electromotor (110) and transmission means (111). The electromotor (110) is controlled by a control device (120). The arm (4) comprises a gripping member (2) with which a weight sensor (130) is associated, which weight sensor provides an electric signal to the control device (120). When the weight sensor (130) detects a decrease of the weight, the control device (120) causes the motor (110) to rotate for displacing the arm (4) upwards. When the weight sensor (130) detects an increase of the weight, the control device (120) causes the motor (110) to rotate for displacing the arm (4) downwards. <IMAGE></p> |
