摘要
Abstract
Due to sliding motion errors of a four-wheeled skid-steer mobile robot,it is difficult to control the robot to follow its trajectory.Also the dynamical parameters of the skid-steer on different ground conditions are different,causing different sliding errors and increasing the difficulty in the control and prediction of the robot's turning linear velocity and angular velocity.The linear velocity and angular velocity calculation model of the four-wheeled skidsteer robot is built with two inertial measurement units,and the model is used to take the closed loop control of the four-wheeled skid-steer mobile robot for its motion control,dynamically adjust four wheels separately and make the robot operate more precisely and smoothly.The experimental results show that with the dynamic wheel-velocity adjustment strategy,the robot runs more accurately with less sliding motion error when its trajectory is followed.关键词
