Also, the small bungee racers had a ratchet mechanism also using several 16T
gears.
I'm quite curious to see what other variations of this platform emerge.

| Yeah, I've made these sorts of ratchets before. The problem isn't so much making a ratchet as it is ratcheting the wheel assembly to the platform. If I had one of those free-spinning dark grey gears I could do it. I may finally have to break down (...) (26 years ago, 14-Jan-99, to lugnet.robotics)
