Abstract

A manipulator for an environment with hygienic requirements, comprising a stationary element (1) with a plurality of drive means (2), and arms (3) attached to the drive means, which arms, via a respective linkage (4), support a movable element (5). The drive means (2) are enclosed in an enclosure (6) which encloses a gaseous coolant which, by a forced flow, takes up heat from the motors of the drive means.
