Abstract:

A concrete incorporation of mobile robots in more industrial applications depends mainly on their ability to navigate safely in industrial environments while fulfilling the assigned tasks. One of the important tasks in wheeled mobile robotics is trajectory tracking, which adds temporal constraints on the robot navigation. The employment of trajectory tracking strategies with obstacle avoidance capabilities is essential to avoid time waste and inefficiency in mobile robots industrial integration. In this paper, we present a navigation algorithm intended for differential drive mobile robots, that combines trajectory tracking with obstacle avoidance. Obstacle detection is accomplished using sonar range sensors and the navigation is found on kinematic control and vector field histogram approach. Demonstration with simulations in V-rep environment is presented where Pioneer3DX successfully avoided obstacles while tracking a trajectory.
