Battlefield Extraction Assist Robot (BEAR)


The US military is developing a robot with a teddy bear-style head to help carry injured soldiers away from the battlefield.
The Battlefield Extraction Assist Robot (BEAR) can scoop up even the heaviest of casualties and transport them over long distances over rough terrain.
The 6ft tall Bear can cross bumpy ground without toppling thanks to a combination of gyroscopes and computer controlled motors to maintain balance.
It is also narrow enough to squeeze through doorways, but can lift 135kg with its hydraulic arms in a single smooth movement, to avoid causing pain to wounded soldiers.
While the existing prototype slides its arms under its burden like a forklift, future versions will be fitted with manoeuvrable hands to gently scoop up casualties.
The Bear is controlled remotely and has cameras and microphones through which an operator sees and hears. It can even tackle stairs while carrying a human-sized dummy.
It is expected to be ready for testing within five years.

1. Teddy bear face designed to be reassuring
2. Hydraulic upper body carries up to 227kgs (500lbs)
3. When kneeling tracked "legs" travel over rubble. Switches to wheels on smooth surfaces
4. Dynamic Balance Behaviour (DBB) technology allows the robot to stand and carry loads upright on its ankles, knees or hips for nearly an hour
