The gripper head of a robot is reduced in size and weight by locating the drive motor and positional and speed control devices to an arm of the robot carrying the gripper head, and connecting the motor to the gripper head by a flexible transmission shaft. A robot 1 (Fig 1) comprises a pedestal 2 supporting a first arm 3 for movement about a hinge 4. The first arm carries a further arm 5 for movement about a hinge 6 and a gripper head 7 is mounted for angular and longitudinal movement in the end of the arm 5. The gripper head 7 includes a pair of jaws 8 whose movement is controlled by gearing in a casing 9 of the head 7. A drive motor 10 for the gripper jaw gearing is mounted in the arm 5, and a flexible drive 11 connects the output of the motor 10 to the input of the gripper jaw gearing in casing 9.
