I gotta see the movie to really appreciate what you'd like to see.

The foot on the obstacle is not in the air but on the ground. If you mean that
one foot is on the obstacle and the other can't reach the ground, I see your
point. I was hoping to add a suspension to Quad242 to make it handle a certain
level of uneveness.
I see what you mean about using a spring loaded switch as a sensor. It is a
good idea. I'll keep it in mind.
So many fun projects..... So little time.

If you look my profile up here on lugnet, you'll see that I've had a highly
articulated long legged spider on the list for a long time.
