Amodeling method called : wheel-center modeling (WCM) for kinematics of awheeled mobile robot that moves on uneven terrain is presented. The vector expression of wheel center velocity is derived based on the analysis of the velocity characteristic of amulti rigid chain’s locomotion and the wheel-model moving mechanism’s moving on uneven terrain. The method of WCM is introduced as aresult. The projection of the angular velocity of the rotary joints in the rover centre frame is analysed and the projection of vector cross product is expressed as different forms according to whether the direction of the angular velocity relatively to rover centre frame changes or not. The wheel centre velocity is projected to the rover body centre coordinate frame with the use of the elements of the homogeneous transformations from the wheel centre frame and the wheel-terrain contact frame to the rover center frame. Thus, the kinematics of the rover is modelled. The procedure of kinematic modelling using WCM is introduced and the characters of WCM is analysed. The method’s validity is verified by experiment and simulation. () 小五 Key words () 小五黑体 : Double glow Artificial neural network Prediction model
