An all-terrain wheelchair with tracks instead of wheels that can go almost anywhere has been developed by scientists.
The Action Trackchair is made by Action Manufacturing in Marshall, Minnesota, and is specifically designed to go off-road, the Daily Mail reported Thursday.
It can power across mud, rocky terrain and even in water. It has a top speed of eight kilometres per hour.
The man behind the world's toughest wheelchair, Tim Swenson, came up with the idea after his son, Jeff, was paralysed in a car accident, the Mail said.
The ability to go off-road doesn't come cheap, though. An Action Trackchair costs $9,000 (5,700 pounds) and is currently sold in the US, Canada, Norway and Australia.
