Swimming Robot
A new robot called Gymnobot from researchers at the University of Bath in England has been unveiled.
Taking inspiration from the Amazonian knifefish, they have created an underwater vehicle that uses a long fin to propel itself.
Not wanting to use a conventional propeller, they have created a long fin under the vehicle that mimics one found on a knifefish. This is more energy efficient and has much less chance of getting tangled in weeds. It also allows the submersible vehicle to travel in much shallower water.
Pictured here are postgraduate researchers Keri Collins and Ryan Ladd from the University of Bath.
