Two-legged robot named 'Cassie' sets Guinness World Record for fastest 100-metre sprint by a droid

A two-legged robot that can chase you down in the street may sound like something dreamed up for the latest episode of Black Mirror. But it may not be far from reality, after a two-legged robot known as'Cassie' set a new Guinness World Record for the fastest 100 metres by a bipedal robot. Cassie clocked the historic time of 24.73 seconds, starting from a standing position and returning to that position after the sprint, with no falls. While that's more than 15 seconds slower than the world record for a 100-metre sprint by a human, held by Usain Bolt at 9.58 seconds, it is faster than most humans would take to jog the same distance. Oregon State robotics professor Jonathan Hurst, who led the development of the robot, described it as'a big watershed moment'.
