REK S.T.E.E.L lets people box through humanoid robots in VR

Real Steel, minus the fiction: REK's new S.T.E.E.L system turns a person's VR or motion-capture moves into real-time punches from a humanoid robot.

Remember Real Steel, the film where people steer fighting robots? A US league called REK has just shown a system that does something very close to it. It's called S.T.E.E.L, and it lets a person throw punches that a humanoid robot copies as they happen.

REK, which describes itself as a humanoid robot fighting league, presented the teleoperation system on the 11th. Teleoperation just means controlling a machine from a distance. Here, the operator wears a VR headset or motion-capture gear, and their body movements are passed to the robot in real time. The robot then carries out combat moves such as boxing.

How does S.T.E.E.L work?

The input side is simple: VR devices or motion-capture equipment record what the person does. The robot mirrors it live. The harder part is the control software in between. According to REK, the team spent about five months developing AI control technology built specifically for real-time fighting.

The company has not shared more detail than that, so questions like how fast the robot responds, which robot models are used or how it handles a hit remain unanswered in what REK has said so far.

What happens next?

REK says what it showed is an early version. The plan is to use the technology in robot fighting events down the line, though no dates or venues were given.

For now, the pitch is easy to picture: instead of programming a robot to fight on its own, you fight, and the robot is your body in the ring. Whether that makes for good sport is something REK will have to prove once the events actually start.
