Playing around with some 3D printed ratchet wheels (ergo, the clicking sound). I slammed this 08M2 1-servo wiggle walker together in an hour yesterday using paint sticks, a tongue depressor, super glue and an MG-995 servo (AKA the world's worst servo). Hardly a dead reckoning champion but decent results in 5 minutes of programming to do a figure 8. This would be a great starter project for kids. Especially now with home school still going on!
