Muscle-Like Piezohydraulic Actuators for Robotic Grippers

Industrial robotic grippers nowadays do not present the required flexibility against changing or individual workpieces. As a result, tools and gripping systems have to be changed often. The human-hand, on the other side, with a huge degree of dexterity can handle many workpieces with a wide variety of dynamic properties ranging from precise positioning up to applying high forces. The goal of this contribution is to demonstrate the usage of the piezohydraulic actuation principle as a muscle-like actuator in the realization of a versatile robotic hand. By combining a human-like multi-fingered robot hand with this flexible actuation principle, a dexterous gripping mechanism can be realized. Fifteen such actuators are integrated in the fore-arm of a 6-DoF robotic arm and drive the tendons of the human-like robotic end-effector. This enables a broader range of objects that can be grasped with such a gripper than with typical grippers, being able to grasp both delicate objects using soft dynamics as well as to realize high forces required in many industrial applications.
