Rise of the killer robots? Scientists develop an indestructible robotic hand ... trends now

A huge, super-fast indestructible robot hand might seem like a terrifying prop from a science-fiction film.

But this hefty 4.1kg (9.9lbs) hand is very real and is already being used to develop the next generation of AI robots. 

Designed by UK-based Shadow Robot Company, this three-fingered claw can go from fully open to closed in just 500 milliseconds.

However, the robot hand is still tough enough to resist being bashed with hammers or pounded by pistons. 

That toughness is designed to help the hand survive the rigorous and often destructive process of teaching AI how to interact with the world.

At about 50 per cent larger than a human hand and with only three fingers, this robot isn't quite as human-like as many others out there.

However, according to Shadow Robot Company director Rich Walker, that chunky design is a necessary trade-off.

Designed over more than four years with AI company Google Deepmind, the hand's main purpose is to help teach AI.

While robots on factory floors are able to follow simple routines like moving sheets of metal from one place to another, the real world requires more complex movement.

To have robots be able to perform more complex tasks or to act autonomously, they will need AI to power their motor controls.

But the process of teaching AI to control a robot is one that can be particularly expensive and destructive for the robots involved.

Mr Walker told MailOnline: 'If you've ever seen a baby learning, in the beginning of the process they move around randomly before it starts to connect those movements with
