An Inflatable Eversible Finger Pad for Variable-Stiffness Grasping with Parallel-Jaw Grippers

Raphael Deimel,Andreas Kugi,Raphael Deimel,Andreas Kugi

We present an inflatable finger pad that allows regular parallel-jaw grippers to vary their grasp stiffness while maintaining a contact force and contact to non-planar surfaces. An eversible radial bellows structure made of silicone rubber allows the pad to extend to four times its original height and to retract into a rigid pod when not needed. The bellows act as passive universal joints when eve...
