Researchers at University of Arizona have created a modular robot made of cardboard and a Raspberry Pi Zero (a simple computer) for around $70.
The form and movement of this little machine is made to mimic a sea turtle, and the cardboard fins can be swapped out for more durable, 3D-printed materials depending on the environment.
Biologists, mechanical engineers, and computer scientists collaborated to create this robot, and they have big plans for it; one day they hope to send it to Mars.
