Construction workers in Cardiff are trialling a new robotic vest designed to help them lift heavier weights for longer.
The Ekso-vest gives workers extra support on the back and shoulders when lifting objects overhead. It works using a spring loaded mechanism.
The designers say it could help prevent injuries.
In California, it's widely used in car manufacturing. But it is said to be the first of it's kind to appear in the UK.
It was trialled at Wilmott Dixon, a construction company in Cardiff, where workers said helped prevent strain on their body.
