Concept for a Virtual Reality Robot Ground Simulator

For many VR applications where natural walking is necessary, the problem of a far smaller real movement space than in VR arises. Treadmills and redirected walking are established methods for this issue. However, both are limited to even surfaces and are unable to simulate different ground properties. Here a concept for a VR robot ground simulator is presented allowing to walk on steep ground or even staircase and which can simulate different undergrounds like sand, grass, or concrete. Starting from gait parameters, the technical requirements and implementation challenges for the realization of such a VR ground simulator are given.
