Kaylene Kau's prosthetic arm isn't your typical robot-arm. It doesn't even have fingers — it's flexible tentacle design would make for an excellent replacement hand for wielding a lightsaber.
As a part of a student project, Kau was asked to "push the boundaries of current upper-limb prosthetic design." Powered by a small motor and a set of cables, the tentacle shaped prosthetic arm curls its claw to grip objects.
Great idea Kau, who needs to Force-choke someone when we can just lock them into a death grip with this bionic tentacle? One question, how do you flip someone the bird? Just wave your whole arm up?
