Bionic robot arms as flexible and gentle as an elephant's trunk

Artificial muscles and nerves made from the shape memory alloy nickel-titanium are making robot arms as supple and agile as their animal counterparts. But these artificial limbs also weigh less, will work tirelessly and can be precisely controlled. The bionic robot arms that are being developed by Professor Stefan Seelecke’s research team at Saarland University in collaboration with the German automation specialist Festo consume very little electric power and can work safely with humans. The research team will be presenting the technology at this year’s Hannover Messe from 17 to 21 April (Hall 002, Stand B34).
