C-Turtle: Cardboard Turtle Robot with Raspberry Pi

Here is a turtle-inspired robot made using cardboard, Raspberry Pi, and other cheap electronic components that can teach itself to navigate different terrains. ASU students developed it with a pair of flippers to push across the sand. It applies enough pressure on the sand to move forward but doesn’t dig holes.

Each robot costs about $70 to make with the motors and chips costing $5 and $10 respectively.  More info is available here.
