MultiChoiceGripper

MultiChoiceGripper

Variable gripping based on the human hand 

In the case of the MultiChoiceGripper, the opposable thumb of the human hand acted as inspiration: Just like its natural role model, the Future Concept combines different grip types. Its fingers can therefore be switched over so that they can either grip in a parallel or centric direction – without requiring any conversion.

Adaptive fingers for the widest range of shapes

The MultiChoiceGripper is not only variable in the direction of grip, however. The adaptive fingers with Fin Ray® structure adapt themselves flexibly to the most varied shapes. It can therefore grip differently shaped and also very sensitive objects without additional sensor or control technology.

  • Besides the Fin Ray® fingers, two other types of fingers can be attached – between two and six depending on requirements.

Potential uses in the future

An application is conceivable wherever many different objects are gripped – for example, in auxiliary robotics, for assembly tasks or in production facilities where various products are made. At the moment, change-over systems often have to be used, which are fitted with different grippers.

Easy changeover: the mechanical changeover between parallel (left) and centric grip direction (right) removes the need to convert the gripper.
