Abstract

This paper presents a novel approach for the problem of tracking a moving target in a dynamic environment. The robot has to move such that it keeps the target visible for the longest time possible, and at the same time, avoid colliding with any of the moving obstacles. This paper presents a solution that is based on the idea of three interacting components which perform: tracking, collision avoidance and motion selection. The proposed solution is validated using a comprehensive set of simulations, which show that transition from tracking in static environments to tracking in dynamic environments can be done without much loss in robot safety or tracking ability.
