What are robot hands

Attempts to make robotic prostheses and functionally relevant motor skills and capabilities of human hands made constantly. The development of such devices is engaged, for example, the Italian startup Prensilia, new products which we'll talk today.
One of the products Prensilia is a high — tech hand prosthesis Azzurra. This robotic arm has five motors that provide 11 levels of freedom. The device can capture subjects in different ways, and even to perform basic gestures — for example, to specify one or more fingers in a particular direction or to bend them in imitation of the account.
Ramoroka, which weighs 640 g, gives the ability to lift objects weighing up to 4 kg. the Developers say that the device provides nearly 80% of the features of the seizure that a person has.



The secret Azzurra — maloprimetny special mechanism that will allow to do, as already noted, only five motors. A special system converts the rotational motion of DC drives in linear motion of the slider controlling an artificial tendon. In the end, only one motor allows the finger to chintsa and raspinatsa with the required amplitude.
