Schunk unveils latest 5-finger robot gripper

The latest Schunk SIH gripper for robots is equipped with five fingers and a structure similar to humans, differing fundamentally from the company’s existing SVH 5-finger hand in terms of drive and kinematics. Whereas the SVH, which is driven via nine motors, complies with the typical aspects of a precision working robot hand, the SIH, which is equipped with five motors and actuated via pull cables, is much more based on its human counterpart, with its veins and muscles.

Three fingers of the SIH can be moved independently of one another, while the two smallest move together as a team. As a result, the SIH can be deployed more flexibly than other gripping hands with pull cable mechanisms. According to Schunk, the device is also more robust and lower in price.

In order to attain the goal of affordable, simple-to-operate 5-finger hands for versatile applications, Schunk makes use of experience from bionics, as well as the latest motor and electronics concepts. Using intelligent gripper control, a wide range of gripping operations can be realised via a simple-to-operate interface without the need for precise programming.
