Here’s a fantastic project that lets to drive a hexapod around the room using an RC controller. [YT2095] built the bot after replacing the servo motors on his robot arm during an upgrade. The three cheapies he had left over were just begging for a new project, and he says he got the first proof-of-concept module put together in about an hour. Of course what you see above has gone through much improvement since then.
The three motors are epoxied together, with the one in the middle mounted perpendicular to the motors on either side of it. Those two are responsible for the front and rear leg on each side, with the third motor actuating the two middle legs. It’s a design we’re already familiar with having seen the smaller Pololu version. You might want to check that one out as there’s some slow motion video that shows how this works.
[YT2095] added control circuitry that includes an RF receiver. This lets him drive the little bot around using a transmitter with four momentary push switches on it. We love the idea of using copper clad for the foot pads.
