Modeling Robot- Soil Interact ion for Planetary Rover Mot ion Control

摘要

In aim to optimize the control for an ofl-road robot and specially a robot with a crawling motion mode named peristaltical motion, it is essential to understand robot-soil interaction. We present an eficient method for simulating this interaction. This method can simulate the dynamic behavior of a 6-wheeled/3axles Marsokhod type robot on different kinds of soils. With this simulation, we have defined the necessary conditions for using the peristaltical motion on sand or loose soil.
