qb SoftHand Research

Born out of research to create a prosthesis that was light, cheap and above all, easy to use, the qb SoftHand Research is the only MechaLogical hand in the world. Thanks to its under-actuated structure, the qb SoftHand Research is able to replicate about 75% of the grips of a human hand, and thanks to its inherent mechanical intelligence it is able to adapt naturally to the objects it is picking without the need for sophisticated sensors that require equally sophisticated electronic programming.

qb SoftHand Research is an anthropomorphic robotic hand based on soft-robotics technology, flexible, adaptable and able to interact with the surrounding environment, objects and humans while limiting the risk of hurting the operators, spoiling the products to be handled, and damaging the robot itself.

The qb SoftHand Research is adaptable and can grasp different objects without any change in the control action, showing an unparalleled level of simplicity and flexibility.

Thanks to its soft nature the hand by qbrobotics exploits the principles of synergies in a simple and intrinsically intelligent design that is safe in unexpected human-robot interaction.

The combination of these innovations results in a flexible prehensile device that can grasp a wide variety of objects. This is what we call MechaLogical. The single-motor actuation makes the hand plug-and-play and simple-to-control (one single motor requires one single control signal to close and open the whole hand) and affordable. The robotic hand qb SoftHand Research can be easily integrated with main cobot brands in the market and is also is 100% compliant with the UR+ ecosystem.

The qb SoftHand Research has been designed for the educational sector and it’s dedicated to research institutes, universities, schools, testing laboratories and R&D departments of private and public companies.
