Two-legged ‘Usain Bolt’ robot breaks world record for fastest 100-metre sprint

Usain Bolt could have his work cut out for him thanks to a super-speedy new robot called Cassie.

The two-legged bipedal robot nabbed a Guinness World Record this year for the fastest 100-meter sprint, clocking in at 24.73 seconds on a running track.

While it's not quite as fast as Bolt's jawdropping 9.58 seconds, Cassie's race is a huge leap forward for robotkind.

Researchers behind the robot say its knees are designed to bend like an ostrich's and that it uses no external sensors or cameras.

“I believe control approaches like this are going to be a huge part of the future of robotics. The exciting part of this race is the potential.

"Using learned policies for robot control is a very new field, and this 100-meter dash is showing better performance than other control methods. I think progress is going to accelerate from here.”

If running robots like Cassie keep on advancing, we could just see them beat human runners one day—and even Usain Bolt himself.
