Accounting for mobile robot dynamics in sensor-based motion planning: experimental results
Juan Carlos Alvarez, Andrei M. Shkel, V. Lumelsky · 2002
The effect of robot dynamics on autonomous navigation is a key issue in sensor-based motion planning. In most of existing works, the solution is attempted by separating the planning and control into two sequential stages; as a minus, this may, for example, adversely effect the algorithm convergence. The strategy proposed in this paper solves the problem by combining motion planning and control within a single-stage procedure. The procedure exhibits good dynamic behavior, while providing safety (collision avoidance) and fast response. Results of testing the approach on a commercial Nomad-200 mobile robot are presented. Also discussed is the effect of model parameters on motion performance.
