The TECHNO CONCEPT Company has developped a mechanical hand with several jointed fingers (3 phalanxes per finger) and an automatic tightening of the objects.

This artificial hand is commanded by a single traction cable which controls the silmutaneous opening of the fingers.The cable relax unblocks the phalanxes - which stop at the touch of the object. Each finger independantly fitts to the object shape.

The tightening is automatic: the sliding - caused by the object weight - generates its overtightening.Weightest is the object, strongest is the tightening.


This hand is fully mechanical without electronics or taps. All the moving parts take position under the action of springs when the cable relaxes.The stresses are supported by parts made of treated steel (not by the cables).

The tightening is suited to the weight. The prehension of light or fragile object, or denser items (several kgs) is the easier and extremely rapid (opening / closing).

This mechanical hand exists in different sizes.

It is made up with :
      - a hand to fix to the robot wrist
      - a traction covered cable along the arm
      - an electrical jack to fix on the robot body

The opening and closing control of the hand is activated by reversing the polarity of the jack electrical supply.
