Meet Sofi: a robotic fish created by MIT scientists

National News

Sofi swims like a fish and acts like a fish, but it’s no fish. Sofi is an 18-inch robotic fish with — what else — a fisheye lens.

Created by a group of scientists at MIT, the robotic fish is made of soft silicone rubber, flexible plastic and 3D-printed pieces. It also has sensors to keep it from running into reefs and other barriers in the sea. 

Sofi swims naturally alongside other fish while spying on them. Sofi currently can’t swim on its own — it has to be controlled by a user. 

The scientists ultimately want to take their technology to biologists who could benefit from the robot’s undersea observations.
