Swiss students develop robotic hand which works faster than human brain

Press Trust of India  |  Zurich 

Students at Switzerland's here have developed a robot which works 30 times faster than the quickest human.

The Institute of Neuroinformatics' "Sensors Group"at the has used a brain-inspired and camera to develop "Dextra a robotic hand" which essentially reads your mind anticipating your hand gestures to defeat you in the rock-paper-scissors game.

"Dextra sees the world in super slow motion. It is so fast at seeing the symbol you are about to throw that it is able to both determine your next move and execute a winning symbol 30 times faster than the quickest human," Professor, told

"Unlike conventional (AI) based on image frames, Dextra wins by being frame-free," he added.

Conventional robotic or computer systems must continually process frames at a very high rate in order to react quickly. in the camera and the system sap and power.

"Dextra's AI drives the motion in the scene by using a silicon retina Dynamic Vision Sensor (DVS) camera and a custom accelerator called, 'NullHop'.

"The robotic AI computation occurs only when necessary enabling the system to always react quickly, while at the same time, optimizing use. It is a (ConvNet) accelerator that determines which symbol the human game displays," he added.

The further explained that NullHop, like the DVS, takes advantage of the sparse data reducing the number of necessary computations by a factor of four.

"By using NullHop and the DVS, the system driving Dextra can react in about 10 milliseconds, about 30 times faster than the quickest human," he added.
