The invention relates to a robot arm arrangement for use in cleanrooms, for example. The robot arm arrangement (100) moves a gripper (102) in an automated or remotelycontrolled way, and the arrangement comprises four arms (104) movably connected to each other so that the arms (104) form a parallelogram. Control means (108) are provided at a first corner of the parallelogram, and the gripper (102) is connected to a second corner (110) of the parallelogram, which second corner (110) is opposite to the first corner connected to the control means (108). The gripper (102) is adapted to be moved around its axis by a belt (106) extending through the arms (104), wherein the surface of the belt (106) is provided with an electrical conductor (120) to transfer energy to the gripper (102). |
