(...) Thanks Steve. Another thought- You know those long oval-shaped arms (one end bigger then the other) that connect the front half to the rear half? I bet there is a chain in there that drives the auger (or blades). Maybe it is the front engine (...) (19 years ago, 13-Sep-05, to lugnet.technic)

(...) (SNIP) (...) This one has moved away from my usual differential logic. Each leg module has a flip-flop for the foot and hip, which does 3 out of 4 movements and waits for the fourth to be done all legs together. I see how single switch AND (...) (19 years ago, 13-Sep-05, to lugnet.technic)

(...) I've never read anything to support this supposition. I've always thought scrapers mainly use mechanical transmissions. I know Caterpillar likes to put mechanical transmissions in things where other makers only use diesel-electric. I'm sure (...) (19 years ago, 13-Sep-05, to lugnet.technic)

(...) Hi Mark, Now I know what to build next..... a four legged walker that lifts one leg at a time. On paper it looks like I can get one made for 1+2n pistons and 2+4n switches. This assumes that legs mechanically lock when weight bearing. I don't (...) (19 years ago, 13-Sep-05, to lugnet.technic)

A while ago I saw an electric robot on TV that had 6 legs in 2 rows of 3 and moved one leg at a time forwards (lift, forward, down), then all back together. I thought this is an ideal application for Lego pneumatics. I don't still have it built, but (...) (19 years ago, 13-Sep-05, to lugnet.technic)
