Aiming at the problem that the path-planning algorithm of indoor mobile robot is most oriented in theory,less applied into pracitce,a kinematic model of the mobile robot was built,a grid-based modeling method was used to divide the indoor environment into blocks,a novel algorithm about indoor mobile robot's path planning for unknown environment was designed with the help of Pioneer P3-DX robot and its simulation software Mobile Sim. The grid mode was built based on the the width of the robot,then thepoint t...
