If you want to build a robot that moves across the ground, the normal options are wheels or legs of some kind. Maker “joesinstructables,” however, decided to do something a bit different. He created a versatile, slithering system, which he calls the “Lake Erie Mamba.”
He put a dozen Arduino Mega-controlled servos together in a reptile configuration to allow the robot to move via serpentine motion (like a normal snake), rectilinear motion (like a worm), or sidewinding (which snakes use in shifting terrain). It can also twist itself into a wheel and roll in this rather unnatural, though quite interesting way.
The Lake Erie Mamba contains 12 segments, each consisting of a servo motor, a C-bracket, a side bracket, a wire clip, and a set of LEGO wheels. The reconfigurable robot is not only controlled using a four-button key fob remote, but can move about autonomously via an IR sensor as well.
You can see more of this build on its Instructables page here and in action below!
