2A2-B04 Mobile Robot System Realizing Human Following and Autonomous Returning with Obstacle Avoidance

In recent years, with the development of industry technology, introduction of autonomous mobile robots to environments close to us is expected. Examples include shopping cart robots automatically returning to the shopping cart shed after shopping, and guide robots directing the way from the current location to the starting location in unknown environment. In this paper, we propose a mobile robot system that has a function of returning to the starting location autonomously while avoiding obstacles which are not present on the way to the current location. We verified the validity of the system by using the wheel mobile robot with LRF.
