Abstract
This paper describes a collision force suppression mechanism that designed on the assumption that a robot collides with a human in our environment. The suppression mechanism is designed and analyzed using SolidWorks 3D CAD software. The suppression mechanism consists of a clutch gear, an air cushion bag, fixed guides, linear ways and tension springs. The mechanism will be operated even if the electric power grid is shut down and a sensor is broken. Depending on the tension spring constant, the operation condition of the collision force suppression mechanism is changed.
