Successfully crafted a moving robot hand like a human hand

Robotic hands move smoothly like real human hands

Developed by Steeper, a UK-based manufacturer of artificial parts, this is the most advanced and hand-like model of hands. This product is the result of 7 years of research and development, applying military technology and using formulas from F1 racing engineers.

Besides, the materials to create this hand include rare earth magnets for finger control systems; and aluminum alloy which is used in the aircraft industry to make this "machine hand" lighter.

Researchers began by creating a structure based on the conventional small-handed architecture and then fitting the mechanical details to create overall accuracy. According to Ted Varley, technical director of Steeper, previous designs often aimed at the previous technology and then formed the structure of the hand, so the resulting product is less similar to the real person.

Developed in accordance with the structure of the hands that help the product work quite well, besides, this artificial hand can perform 14 different holding postures. There were 337 mechanical details used to form this " mechanical hand ", its size was also scaled to better suit women, teenagers and small men.

Although many mechanical parts are installed, the total weight of this hand is less than 400 grams. Some people will think that with such a mass, how can this " manipulator " do heavy work? According to the developer, this hand can withstand up to 99 pounds, or 45 kg.

Nicky Ashwell and his new hand.

So how does this hand work? The inside of this hand has many different sensors to read user motions, then send information to the motors on the finger and the processor to control these fingers. Besides, this machine's hand also has an auto-grip feature, when it detects that something is coming out of the hand, this device sends processing information and this hand will quickly catch up with the object. That is not to fall off.

Ashwell uses a very mature robot arm.

This artificial hand was recently installed for a 29-year-old woman named Nicky Ashwell, who had lost her right arm when she was born. Previously, she used a prosthetic arm, but it was unable to move and almost Ashwell could not take advantage of the majority of functions that a normal hand could bring. Now with this new hand, Ashwell said it helped improve most of her life, as well as helping her do more jobs that were previously impossible.
