A bipedal robot holds the 100-meter world record!

Recommended for Middle Grades

The 100-meter dash Guinness World Record is set by a robot named Cassie. Cassie is a kind of research platform for building robots. It came out for the first time in 2017.

Cassie ran 100 metres in 24.73 seconds, which is a new Guinness World Record for a robot that can walk on two legs.

To do this, the robot needs to be able to run, which is done through a process called “machine learning.” So that it can stand up straight, the robot’s knees bend like an ostrich’s. So, the technology helps the robot keep its balance and posture while it is running.

Key facts!

  • Cassie has been used to do research on how robots learn to move.
  • It is a mobile robot that moves on its own.
  • Cassie did a week’s worth of training that was meant to be like a year’s worth.
  • Researchers spent a week speeding through it to figure out the best speed for Cassie to run.
  • Cassie had to start the race standing up, cross the finish line, and then go back to standing up right away for the Guinness World Record to be valid.
  • She couldn’t just sit down.
  • Cassie used two networks. One helped her move quickly, and the other helped her stay still.
  • She moves easily from one to the other.
  • Scientists say that starting and stopping from a standing position is harder than running itself.
  • This 100-meter result was made possible by working closely on the design of mechanical hardware and on the use of advanced AI to control that hardware.
