A terrifying legged robot has beaten its own speed record and bagged a world first by reaching 28.3 mph (45.5km/h) over 20 metres in a lab trial. The beast is currently locked up in the DARPA research facility.

The galloping bot is officially faster than the fastest human - Usain Bolt who reached 27.3 mph (43.9km/h) in 2009, setting the top limit of human speed.

The metal-legged robot, called "Cheetah", is a project of Boston Dynamics and funded by the US's Defense Advanced Research Project Agency (DARPA). The metal-legged runner is a step on the way to making rough terrain military robots that could traverse ditches and walls that wheels and caterpillar tracks can't.

But legged robots are much slower than bots on wheels and so the team have been working on improving the speed and resilience of robots with legs. The Cheetah is the fruit of the research and the fastest legged robot to date. The new speed record breaks Cheetah's previous speed record of - 18 mph (29km/h) - set in March 2012.

Improved algorithms controlling the sequence of the leg movements and a stronger hydraulic pump powered the robot to its new record, say the bot-boffins behind the Cheetah.
