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'.

'This may be the first bipedal robot to learn to run, but it won't be the last,' he said.

The 100-metre record builds on earlier achievements by the robot, including running 5 kilometres in 2021 in just over 53 minutes.

Cassie completed the 5K on Oregon State's campus untethered and on a single battery charge.

The robot has knees that bend like an ostrich's and operates with no cameras or external sensors - essentially as if blind - using machine learning to control its running gait.

'We have been building the understanding to achieve this world record over the past several years, running a 5K and also going up and down stairs,' said graduate student Devin Crowley, who led the Guinness effort. 

'Machine learning approaches have long been used for pattern recognition, such as image recognition, but generating control behaviours for robots is new and different.'

While completing a 5K helped to prove Cassie's reliability and endurance, it left open the question of how fast the robot could run. 

This led the research team to shift its focus to speed.

Can a human EVER run 100 metres in under nine seconds? 

The main issue in achieving a sub-nine second race is how much power humans can produce, and what the requirements are to achieve this.

To produce long steps at a high frequency, athletes must produce a huge amount of force in a very short period of time – approximately 4.5 times their body weight in around 0.1 seconds, according to Polly McGuigan and Aki Salo, lecturers in Sport Biomechanics at the
