Objects such as a pen with which you intend to write, or an egg that you do not want to break ahead of schedule, must be held in specific ways and applying a specific amount of force. We humans can do this quite easily with our hands. It has not been easy to achieve the same with the hands of robots, and this has usually been accompanied by expensive and cumbersome solutions. Now a new robotic hand promises to revolutionize the field.
Kieran Gilday, Thomas George-Thuruthel and Fumiya Iida, all from the University of Cambridge in the UK, have designed a low-cost, low-power robotic hand that can grasp objects of many different kinds, without damaging them from pressing too hard or on them. for releasing them improperly. For this, the ability of the hand to perform wrist movements and the sensitivity of its “skin” have been essential.
The new robotic hand has a soft exterior, is made by 3D printing and while it cannot move its fingers independently, it can perform a vital series of complex movements.
Due to its characteristics, the robotic hand is much easier to control and much more energy efficient than robots with fully motorized fingers.
The creators of the new robotic hand think that its adaptable design could be used in the development of low-cost robots capable of executing more natural movements and learning to grasp a wide range of objects.
