as long as you don’t buy the arm at that site use vex parts only =)
I have used a vextroller stripped of its case as the controller for a CrustCrawler Nomad http://www.crustcrawler.com/products/nomad.php?prod=3 instead of the Parallax controller (P annoys me).
I integrated the VEXtroller mostly because I already had working code for image following on the vextroller and it was easer to convert the stride code to C than to convert my camera code to a BS1 (if it would even run). My camera was one of the non-IFI CMU2 cams.
I’ll post pictures when I find them.

i think that making a http://www.lynxmotion.com/images/Products/Full/l601.jpg would be rather easy to make out of only VEX…but mounting that LARGE mass onto a VEX would be a trick.
Now, this http://www.crustcrawler.com/products/nomad/pics/nomad_pic4.jpg is AWESOME! How long did it take you to completely finish?
The Nomad itself can be built in a (very) long day. The CMU cam modifications, and re-building a vex w/o the plastic case and plugs took me a lot longer; 2-3 weeks.

hey i’m almost done making an arm out of the vex. but there is a few mod’s i’ve done to it. like for starters it’s on tank treads for mobility. the lower frame has 2 motors for drive and it also is supporting out riggers the devices that stabilize like fire trucks and bucket trucks… so there are 4 motors on the lower half and 5 motors and 1 servo on the arm. the arm and all it’s electronics are located on the upper half. so as it makes full 360 turns nothing will be tangled. i have 2 vex micro controllers running and i just switch out the crystals in the transmitter so i can move it all around and secure it then change the crystal to move the arm. but here is my problem. i have the shoulder, elbow, wrist (a) and wrist (b) but i need a pincher and am having difficulty just thinking of a simplistic way i have a design but it’s complex and the hand will be nearly 3 times bigger than the arm. i will post pics of my progress tonight after i re mod my support pillars and change the length of it’s forarm to reduce some weight. i will post it all in a new thread.
that website has some pretty cool robots. i think ill try and make one of those arms next.
