Exo Hand
An exoskeleton that can be worn like a glove and can also be used to operate an external robotic arm. The exoskeletal hand has all the principal physiological degrees of freedom of its human counterpart. It thus supports the human hand’s diverse techniques for grasping and handling objects. By means of force feedback, the person feels what the robot is gripping. This means that the human sense of touch can also be made use of across large distances and can even be applied at the interface between the real and virtual worlds. The shape of the ExoHand is adapted to the user’s own hand and made of polyamide using selective laser sintering (SLS).

In a topsy-turvy world, we humans often take for granted our ability to pick up and handle objects of different weights and sizes. We’ve probably all had the experience of picking up a suitcase that we assume is quite heavy and realizing that it’s completely empty.
