On the Impact Force Reduction of a VGT-Robot-Structure with a Variable Compliant and Damped Hydropneumatic Actuator

Abstract:

This paper presents a danger analysis for a new octahedron-shaped variable-geometry-truss robot structure under collision with a human head. To lower the danger of collision, design modifications featuring a decoupling of the robot’s moved mass with variable passive compliance and damping will be introduced and a possible implementation in the robots drives is shown. The paper closes in presenting the impact force reduction potential of the resulting hydropneumatic actuator.
