If the considered a two-legged robotic chasing you down within the streets retains you up at evening, then you’ll be able to sleep simple … for now. A droid named Cassie has set a Guinness World Report for the 100-meter sprint by a bipedal robotic, and whereas it’s removed from the blistering tempo of the world’s greatest athletes, it’s a powerful demonstration of robotics and engineering.
Cassie is the brainchild of Agility Robotics, a spin-off firm from Oregon State College, and was launched in 2017 as a sort of developmental platform for robotics analysis. And Cassie has continued to return alongside in leaps and bounds since then, in 2021 demonstrating some spectacular progress by finishing a 5-km (3.1-mile) jog in simply over 53 minutes.
This achievement concerned using machine studying algorithms to equip the robotic with a capability to run, overcoming its distinctive biomechanics and knees that bend like an ostrich to stay upright. With this functionality, Cassie joined a gaggle of operating bipedal robots that embody the Atlas humanoid robotic from Boston Dynamics and Mabel, billed because the world’s quickest knee-equipped bipedal robotic. However in optimizing Cassie for the 100-meter dash, the researchers needed to head again to the drafting board.
“Cassie has been a platform for pioneering analysis in robotic studying for locomotion,” stated Oregon State College graduate scholar Devin Crowley. “Finishing a 5-km was about reliability and endurance, which left open the query of, how briskly can Cassie run? That led the analysis staff to shift its focus to hurry.”

The staff spent per week fast-tracking Cassie by a yr’s price of simulated coaching designed to find out the best gait. But it surely wasn’t merely a matter of pace. For the Guinness World Report to face, Cassie needed to begin in a standing pose, after which return to that pose after crossing the end line reasonably than merely tumble over. This meant Cassie had to make use of two neural networks, one for operating quick and one for standing nonetheless, and gracefully transition between the 2.
“Beginning and stopping in a standing place are harder than the operating half, just like how taking off and touchdown are tougher than truly flying a airplane,” stated synthetic intelligence professor Alan Fern,. “This 100-meter outcome was achieved by a deep collaboration between mechanical {hardware} design and superior synthetic intelligence for the management of that {hardware}.”
In the end, Cassie accomplished the 100-meter dash in 24.73 seconds, establishing a Guinness World Report for a bipedal robotic. It is a nice deal slower than the sub-10-second occasions run by the world’s greatest sprinters, however the researchers imagine progress will solely speed up from right here. Guinness World Information factors on the market are different information held by fast-moving robots, however as this one relies on an ordinary aggressive activity undertaken by people, it’s a “concrete milestone in robotic locomotion and real-world functionality.”
