An eccentric inventor has created a bizarre four-legged robot that allows snakes to'walk'. Allen Pan, a Los Angeles-based engineer and YouTuber, created the device out of a long tube and four plastic legs connected to a controller board. Footage shows a snake curiously poking its head out the end of the device as it's serenely transported around the room. Pan, who posted a video blog of his project to YouTube, said he wanted to'give snakes back their legs'. Around 150 million years ago, snakes had visible legs, but they evolved to lose them, thought to be due to a genetic mutation.

Google's bizarre four-legged robot called Spot has started delivering parcels in Boston. The canine-like machine can jump, climb stairs, get back up if it falls and even withstand a kick. Its inventors said Spot is '70 per cent of the way' through its trials and may one day be used to deliver parcels all over the world.
