摘要

The drive arrangement for a freely moving robot produces variable movement and comprises a rotating unit (24) coupled to and driven by a torque-generating global drive unit around a rotation shaft. The rotating unit incorporates a local drive unit (56) and a movable bar holder (52). The movable bar holder holds a thrust bar (26) and is moved by the local drive unit, in order to make possible a variable symmetrical movement of the thrust bar which, dependent upon the bar holder position provides a variable effect.
