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.
