Hi,
Here is one more small walker:
Cool!

How few legs does a tank-steer walker need? I built one with eight previously
but six should be doable. Now it needs to be done minimalistic. Hm...

Hi Tobbe,
I think four legs would be enough: build it so the legs on a given side are 180
degrees out of phase.
To turn, run only one side with the other side stopped so both legs are touching
the ground.
Driving in a strait line can be achieved in two ways: synchronize the two sides,
so they are 90 degrees out of phase or drive each side alernatively for one
turn...
Now we have to build it to find out! I guess that what rainy weekends were
invented for...

Greetings,
David

(...) I have been working on pneumatic designs for a quad walker, where it always has 2 feet on the ground, and the transition between pairs of feet has four feet on the ground. This prevents vertical lurching associated with 180 phase quadraped. (...) (21 years ago, 7-Nov-03, to lugnet.technic)
