- Abstract:
- Suitable path planning is a precondition of the autonomous robot exploration in outdoor unknowncomplex environments. The conventional path planning methods focus particularly on planning an un - colli-ding path from the start position to the goal position.Robot attitude stability and its dynamics are seldom con-sidered. A new path planning approach considering the robot ’s attitude stability and energy consumed in out-door complex environment is proposed,which consists of three steps: ( 1 ) gradient calculation,the gradientsof the rough terrain are calculated;(2) nodes detection,the terrain is divided into flat regions and rough re-gions according to a height threshold;(3 ) path evaluation，the optimal path from current position to goal viaintermediate nodes is planned based on the cost evaluation function. Furthermore,robot dynamic characteris-tics are analyzed through back - stepping control, suitable control law is proposed which ensures the stable mo-tion of robot. Compared with the conventional approach,the effectiveness of the proposed method is demon-strated through simulations.
