This four-legged Mechanical Turtle crawls when motor rotation is transferred to the legs via crank plates and linkage rods. The front leg plate is attached with a ball joint that serves as a fulcrum to imitate a real turtle.
This is a programmable autonomous robot prebuilt kit that can be controlled via USB gamepad. The MarvelMind IPS (Indoor Positioning System) provides indoor navigation. ODROID-XU4 single-board PC provides the most flexible platform possible.
