Sue Austin, an artist in the UK, can see the wonders of the ocean without leaving her wheelchair:
To move through oceanic depths, the wheelchair uses a propeller and fins positioned at the back of Austin’s legs that allow her to steer via an acrylic strip attached to her feet. According toSmartPlanet, the design originally proved challenging since most propeller models rely on hand movements, but Austin lacks the strength to maneuver them properly. Instead, the team worked to make her wheelchair more buoyant by modifying the heel plates into fins and tweaking the seat to cope better with underwater pressure.
