this is the initial modification of my original walker design now with a spine that has twisting the spine between the front and the hind legs so that it change direction. also, i added the power functions IR remote control.

i find it quite problematic that the power function motors and servos are actually all three bits long, they should be four imho. you always have to make the design more complex than necessary.

the spine also has to become more elegant and reduced but at the same time more reliable. it’s also becoming obvious that we need more grip at the feed…
