The giant robot, built in South Korea, works by repeating the actions of its pilot sitting inside by moving its enormous arms and legs up and down.

Scientists have programmed a monster one-tonne robot that can walk and mimic human movements resembling something from Avatar .

The METHOD-1 machine is four metres tall and when it stomps it leaves the ground "shaking", according to designer Vitaly Bulgarov.

A control room just big enough for a human operator to squeeze in sits where the robot's chest should be.
