ExoHand

ExoHand

New areas for action for man and machine 

Whether for assembly work or remote manipulation, in the service robotics field or medical therapy, there are many conceivable application areas for the ExoHand. The pneumatic exoskeleton is pulled on like a glove, supports the human hand from outside and thus improves its strength and stamina.

Strong hand with excellent instincts

With the aid of the ExoHand, the individual fingers can be moved and their strength is thereby reinforced. Conversely, the exoskeleton can also mimic the movements of the hand and transfer them in real-time to the robot’s hands. 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.

Tailored fit and positionally accurate control system

The shape of the ExoHand is adapted to the user’s own hand and made of polyamide using selective laser sintering (SLS). It is moved by eight pneumatic actuators. The forces, angles and distances are captured by sensors. A CoDESys-compliant control system records and processes the position and force values and enables the second hand to be precisely aligned.

Potential in a wide range of fields

With the ExoHand, Festo is continuing the efforts made in the research field of interactions between man and machine. The aim is to improve the strength and stamina of the human hand, to expand the human scope of action and to ensure independence even in an old age.
