Touch-pen interface with local environment map for mobile robot navigation

In this paper, we propose a robot navigation interface using a touch-pen. Generally, the global map building and position estimation are very difficult in the disaster site. In the proposed system, local sensory information is mainly used for the robot navigation. The local environment map is displayed for a robot operator, and the operator inputs the goal point on the map for the robot navigation. The desired trajectory and velocity are calculated according to the operatorpsilas command and then the robot automatically moves to the goal position.
