Cassie's roughly 40 supporters were elated, cheering when it crossed the finish line. Its success was a seminal moment in robotic history, they said. Cassie's speed and agility, honed by artificial intelligence training, showed that bipedal robots could maneuver in taxing real-world situations while maintaining balance, a problem that has plagued designers in the past.

Robot makers have turned to nature for their latest creation – a two-legged machine that walks like an ostrich. Called Cassie, the bipedal robot has a unique leg design that looks similar to the large bird, allowing it to crouch down and easily stand up without falling. Although the machine is intended to be a development platform, Researchers foresee its design being used to develop robots that deliver packages or assist in search and rescue missions. Robot makers have turned to nature for their latest creation – a two-legged machine that walks like an ostrich. Cassie is changing the game for two-legged robots.
