Abstract

The invention relates to an actuator (14) for a robot arm segment (12a) of a robot (12), comprising an electric drive unit (15) and a drive-effectively connectable gearbox (1) thereto, which are arranged in a stationary housing (2a), wherein a coil spring (3) is arranged in the power flow between the electric drive unit (15) and the gearbox (1), wherein the coil spring (3) is configured to transmit a drive torque from the drive unit (15) to the gearbox (1) and to support a torque directed from the gearbox (1) to the drive unit (15) against a cylindrical friction surface (4). The invention further relates to a robot (12) with such an actuator (14).
