A coil-powered robot fish designed by scientists at the University of Bristol could make underwater exploration more accessible.The robot fish was fitted with a twisted and coiled polymer (TCP) to drive it forward, a light-weight low cost device that relies on temperature change to generate movement, which also limits its speed.
