Stability analysis of an asbestos removal mobile manipulator for safe grinding trajectories

Abstract

Process of robotic asbestos removal from rehabilitation sites involves dynamic interactions between the abrasive grinding tool and the surface to be cleaned. Moreover, necessity of compact manipulator design yields a mobile base with smaller support polygon. In such case, stability becomes a critical issue. This paper presents an approach for stability estimation by analytically simulating grinding operation. Based on results of stability analysis, a grinding trajectory while ensuring manipulator stability is proposed. Analytical results are then validated through co-simulation.
