oke another hexapod,
this one is made whit inspirations of Kevin L. Clague (e-mails)
it uses the schema from his inchworm for leg lift and drop, and the leg swap is
just slave of the lift and drop pistons.
the front and the rear legs uses elbow extention (just like my hexapod
http://news.lugnet.com/technic/?n=14382 )
i think my walker is to light, it is just scratching the surfase :(
i've made 3 segments to steer my MOC but it turns out it dont work, i need to
order a couple of one way valves to hook it up, but steering whit a midstop
don't work so i did not bother hooking it up.

please let my no what you think of it :)

Hey that is amazing! I'm trying to imagine it moving and working.
I need help!
Very nice symetry you have with the central body and the pistons at angles.
Wow. What a technical triumph.
Excellent work.
Video?

thanks

on it is'nt, it dont work the way i plant, the leg swap (large piston) is to
powerfull, so whan it is moving back it moves to fast and it scratching the
surfase to much!!

Hi Sigurd,
I am always intrigued by walkers, and this one has particularly
intersting features. Is it completely auto walking, I mean if you feed
it air, it walks? How long does it take per step, and how long per
cycle? What is the gait it uses? What are that stats - how many
valves, large/small cylinders does it use overall, and how does that
break down per leg, plus the main central control set (if there is
any). How is it steered?
Would a penumatic circuit diagram for a leg be possible? What is the
rubber band loaded system using two pulley peices attached to a
pneumatic valve about? I just have so many questions about this rather
amazing bot.
Could any of your problems be solved by using the earlier discussion
about gaining access to the "fourth port"? As opposed to using a one
way valve? That may allow sucessful mid-stop if that is what you
required.
I would love to see the video. Does the video have sound - with
pneumatic I just thought - if you want to avoid a bandwidth drain, how
about stuffing on eDonkey and handing out the tracker link?
It may not work exactly as palnned yet sigurd, but I assure you, it is
most definately still a triumph.

it uses 2 control pistons, how operates 2 swiches each.

each leg uses 4 swiches for leg lift and drop, those 4 swiches are all linked
toghter and operates 2 swiches.
the frond and rear legs also have elbow extention, how is linked to the leg
swap. the frond legs have an extention in his elbow whan it is in front
position, and is contrext when it is in back position. the rear legs are just
opposite.

its to steer the hex, if i hook the steering part up, the outside to should by
linked togeter so there is presure coming from the control unit whan it's in his
senter position

a midstop is'nt the problem, but i need extra pices and it did not turn to well
when i put it in the turning position

What I mean was to use one of the peer-to-peer filesharing networks to
share the file, and save yourself the bandwidth of distributing it.
Something like eDonkey, which you can simply put a link on a page to.

Hi Sigurd,
Would it help your mid-stop steering if you spaced the axle joints of the outer
mid-stop valve switch levers further apart (reducing their angles relative to
the centre switch)?
With the same spacing of the valves along the beam, I have the levers spaced
apart with a 1x4 brick with holes:
http://www.brickshelf.com/gallery/mbellis/Technic/Pneumatics/Trinary-Logic-System/cascaded_trinary_logic_evo1_zoom.jpg
See the right of the picture, behind the axle joints, that the distance between
the black 3L pins in the outer two valve switch axle joints is 4L, with the pins
having the slightly narrower end touching the brick. The slightly wider end is
above the axle joint. The difference in these two distances can be critical in
order for mid-stop steering to work.
I used 2L liftarms and cams to make the 1x4 brick with holes move in a
parallelogram along the beam, moving with the centre valve switch, rather than
the brick rotating around the pivot of that switch as your 24mm pulley does.
Sorry it's a bit difficult to see!
Nice robot!
Mark

the problem is not the mid-stop system, but the hexapod dont turn as i expected
(it don't turn at all) when it's body is curved.

thanks anyway, your midstop system looks impresive!!!
