China's robot, which beat Usain Bolt's 17-year-old record, beats its own record

China's Tiangong Ultra robot, which broke Usain Bolt's 17-year-old record by completing a 100m sprint in 9.39 seconds, has broken its own record after just three days. The robot clocked 8.86 seconds in the 100m sprint at the World Humanoid Robot Games in Beijing, China. However, after a planned crash into a cushion, the robot fell back and caught fire.
