This Two-Legged Robot Can Run Without Thinking

Fears that robots who think for themselves could one day spell the end of the human race may soon be settled by a new breed of machine that can move without needing an onboard computer—or it could be the beginning of a brand new cornucopia of concern.

The world's first bi-pedal robot that can balance while running without using a computer processor or sensors was developed by engineers at the Institute for Human and Machine Cognition (IHMC).

"The work is changing how we see nature, engineering and programming when it comes to natural, fast, efficient motion," Johnny Godowski, a research associate at IHMC, tells Newsweek.

Two-legged robots usually need gyroscopes, sensors and processors to measure feedback in order to stay on their feet. The ground-breaking design of the IHMC's running robot allows it to move forward at up to 12 miles per hour without falling over, simply through its mechanical design.

A video of the Planar Elliptical Runner was published Wednesday, May 2, following an open day at IHMC's Florida research facility.

"The robot is 'open loop stable.' There is only one motor driving the legs," IHMC said in the video's description. "There are no sensors or computers on board. An RC car radio controller determines how much power to apply to the motor. Give the robot more power and it runs faster. Less power and it runs slower."

The Planar Elliptical Runner can currently only move in one direction, but the robotics researchers are exploring ways to improve its movements to three dimensions.
