'Star Wars' robotic arm leads the way in prosthetics technology

A robotic arm for amputees named after Star Wars character Luke Skywalker is more lifelike and able to perform complex manoeuvres – a huge advance over the more common metal hook.

The US Food and Drug Administration has approved the sale of the DEKA Arm System after reviewing data, including a US Department of Veterans Affairs study in which 90% of people who used the device were able to perform complex tasks. These included using keys and locks, feeding themselves, using zippers and brushing and combing hair.
