World-beating technology developed in Plymouth is about to revolutionise the wheelchair.
The iBot will cost about $29,000 (£18,000) when it goes on sale
The iBot is a new type of wheelchair that can walk up and down stairs.
It was made possible thanks to new technology invented by BAE Systems in Plymouth, formerly British Aerospace.
It is a cousin of the Segway, the two-wheeled human transporter for able-bodied people, also enabled by BAE technology from Plymouth.
Richatrd Windmer of BAE Systems, said: "People might have associated the plant with military programmes, but we are now moving into the area of automotive field.
"And this really is world-beating technology."
BAE scientists developed miniature motion sensors based on a new type of silicon gyroscope - tiny solid-state gyroscopes that do not actually rotate.
Plymouth-developed gyroscopes are at the heart of the iBot
The iBot, developed by US firm Independence Technology, relies on information from the motion sensors in order to move its highly-articulated wheelbase.
It is not available yet, but this week the iBot got approval by the powerful US Food and Drug Administration.
At $29,000 (£18,000) each, it will remain beyond the spending power of many wheelchair users.
Independence Technology is negotiating with US private medical insurers to pay for the wheelchair.
