This snake robot was built by[Lars] and [Aske] for the DTU Robocup. I’ve seen snake robot before, but I like the concept and the clean electronic design. They used a single AtMega32 controller to generate PWM signals for each of the eight servos, and used a very interesting DC-DC buck converter that’s capable of delivering 16 amps.
For the curious, the bot won the best design and effects award at the competition.
The robot consists of nine cars connected with eight Futaba servos controlled by a microcontroller. All wheels are passive, the locomotion comes entirely from lateral undulation, which is wave movements in the plane similar to a snake.
