(...) 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.
