Abstract: On joining a fibre-reinforced plastic part, such as a plastic fibre-reinforced robot arm, to a functional element such as a gear, as a result of the flow characteristics of the plastic in the case of a high pressing action or high pressures, the joints are no longer stable or resistant and instead tend to loosen. To obviate this problem, the invention provides a fibre-reinforced plastic part, in which several metallic parts (6) engage through at least one fibre-reinforced shoulder (4). On one side of the shoulder or shoulders (4) is provided at least one metallic abutment (8) engaging over several metallic parts (6) and a functional element (2) is braced from the opposite side of the shoulder or shoulders (4) with the abutment (8) against the front ends (6a), facing the latter, of metallic parts (6).

Abstract: A device for compensating the weight of a robot arm of a robot with a spring cylinder and having at least one helical spring is characterized in that there is at least one mechanism for the insertion and removal of at least one further, replaceable helical spring and preferably a pretension of at least the replaceable helical spring is adjustable. The device according to the invention makes it possible to modify the spring constant of the spring cylinder in order to individually adjust the compensating force desired for compensating the weight of the robot.
