Robotic Fish Could Revolutionize How We Study The Ocean

Meet SoFi, the little robotic fish that could help change the way we study the ocean. Created by researchers at MIT, SoFi is capable of swimming alongside real fish without any disturbance, this is due to the robots appearance and movements mimicking that of marine life.

SoFi is powered by a smartphone battery and controlled remotely - using ultrasonic signals to communicate. A hydraulic pump moves its flexible, soft silicone tail, allowing it to move nimbly in the water. 

The robot is still in development, and the team plan to improve its swim speed and design, eventually including technology to allow SoFi to swim autonomously.
