A robotic fish swims in the ocean
A team from the Massachusetts Institute of Technology's Computer Science and Artificial Intelligence Laboratory (CSAIL) has unveiled "SoFi," a soft robotic fish that can independently swim alongside real fish in the ocean. Using its undulating tail and a unique ability to control its own buoyancy, SoFi can swim in a straight line, turn and dive up and down. The team also used a waterproofed Super Nintendo controller and developed a custom acoustic communications system that enabled them to change SoFi's speed and have it make specific moves and turns. The project is part of a larger body of work at CSAIL focused on soft robots, which have the potential to be safer, sturdier and more nimble than their hard-bodied counterparts. Soft robots are in many ways easier to control than rigid robots, since researchers don't have to worry quite as much about having to avoid collisions.
