My Quad242 has the ability to walk forward and backward, as well as turn right
or left.  Currently pneumatic switches, acting as pneumatic polarity reversors,
need to be manually flipped to change from behavior to behavior.

i know what you mean
but i thought about walking through obstacles
in fact walking over obstacles

because we were talking about WWW and the spider from this movie
i mentioned a walker which would walk not just on the flat surface
i'm absolutely sure you can (and will) do such a walker

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


i'll try to explain how i imagine a bot foot which could work as i mentioned in a previous post

let's say the foot is as heavy as it can move the valve from one end to the oposite
(or the foot is stressed by shock absorber or rubber)
so if it hangs the valve is set on the bottom position
when the leg is set down
the foot touches the ground as a first part of leg
then using the weight of leg the valve switches itself
and the robot knows it touches the ground
this happens even if the ground is "now" higher or lower than on the previous foot print
and of course if the leg is going up the foot stays on the ground untill it switches the valve again
so now walker knows its leg is in the air

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.


i hope it could work

let me know what you think (and what you achieve) :)))

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.
