Since there are sudden changes of the obstacles such as market shelves and people at a market, we need to develop sensitive obstacle avoidance algorithm to deal with the change of the map data around the robot for achieving safety among people and the mobile robot. This paper considers the obstacle avoidance algorithm based on the flexible vector field and the active window. The main idea of this...
In the public space, we need first of all the map building to guide the person into the desired position. For realizing this functionality, we propose the fast map building method combining the wall following algorithm and the segment estimation algorithm. First, the process of fast map building algorithm is introduced and secondly, the navigation algorithm for following the surface of a wall by IR...
