In this paper, a digital prototype of a novel robot system for the sustainable mobility assurance in the assistance and care is presented. In contrast to established systems, the new robot system renounces totally the use of wheels as the locomotion concept and uses two serially arranged parallel kinematics (hexapods) instead. As a ride-on device, the system offers high mobility and is able to move forwards, backwards, and sidewards as well as automatically recognize and overcome obstacles. Furthermore, the telescopic motion of the legs enables the handling of steps, stairs, and low clearances.
