Control of a flexible bracing manipulator

Many applications of robotic manipulator arms require operation in contact and noncontact regimes. Control of impact between the arm's tip and the environment has been largely ignored in prior research. The impact phenomena was investigated through simulation and experiment for the realization of the bracing strategy, and the key factors of the behavior were understood well. The approaching velocity is dominant parameter for the magnitude of the impact force. The impact is also affected by the compliance of the environmental surface.
