24.73 seconds! Bipedal robot Cassie challenges 100-meter run and sets world record

In the field of bipedal robots, Cassie from the robotics company Agility Robotics can be called a representative. Agility Robotics is a robotics company spun out of Oregon State University (OSU). It was founded in 2015 and has received funding from the U.S. Defense Advanced Research Projects Agency. Cassie was the company's first product and was sold between 2017 and 2019.

In 2021, Cassie ran her first 5K in 53 minutes. According to the pace of human players, 10.6 minutes per kilometer is equivalent to a "walking level" level, but for robot players, it is a big improvement.

After showing off her long-distance running results last year, Cassie showed the world her sprinting ability today. It set a Guinness World Record for the 100-meter race for a bipedal robot——It took 24.73 seconds, and the average speed was just over 4 meters/second. This is already very fast for a traditional bipedal robot.

#At the same time, this is also the most ostrich-like biped robot so far, but the speed is much different. A real ostrich can run 100 meters. It only takes 5 seconds.

Let’s first appreciate Cassie’s “heroic appearance” on the 100-meter track.

Start from a standing position.

Almost fell down, but adjusted his running posture in time.

## also crossed the finish line in a standing posture.

After running and walking.

It is worth noting that this version of Cassie does not run autonomously. It is not equipped with external sensors and needs to be taken by someone next to it. Use the remote control device to control the steering.

Oregon State University’s Dynamic Robotics Laboratory has been studying the dynamic locomotion of bipedal robots, specifically targeting sprint events that require additional training related to simulated gait optimization. For Cassie's 100-meter race, One of the most difficult challenges faced by researchers is to have it start from a standing position and then slow down until it stops at the end without falling over .

Jonathan Hurst, co-founder and CTO of Agility Robotics, said, "This should be the first bipedal robot to learn to run, but it will not be the last."

He believes this control method will become an important part of future robotics. Applying learned strategies to robot control is a very new field and has shown better performance than other control methods in the 100-meter dash.

In the future, we can look forward to more bipedal robots participating in running competitions.
