The Vex gears aren't high quality so I was never able to get it to balance, but other then that he's a pretty sturdy little guy. http://www.roboticsguy.com/current_projects.php

As a disclaimer I'm not 100% sure on this

The Vex controller is hooked up to your PC through a serial interface, what I assume happens is this. You download the "online code" to your controller and this code knows exactly what bytes are coming in a certain order. For instance:

Byte 0: PWM1 value (0-254 = 1 byte)
Byte 1: PWM2 value (0-254 = 1 byte)
....

So the "communication standard" is just a predefined set of bytes sent back and forth.

If you're wanting to write a computer program to control your Vex robot cool! Go for it. It's definitely possible, although it will take some work.

I'm really looking for a straight Vex controller, but I'd probably take it all off your hands if the price was right.

I'm not sure anyone even reads this Forum any longer, most of the posts are quite old, but ...

I'd like to acquire a second controller for some (possibly destructive) experimentation. I'm hoping to find a decent price on a used one that still works.

Have you found a solution yet??? I have worked with the Line Followers with EasyC 1.1, but 2.0 should be simular.

Try this for starters:

No prob. I think I only gave the bare minimum info too.. (since it was all I had at the moment.)

Interesting video.. aside from the claw at the end of the linear slider, the design looks like a VEX-ified version of
Theo Jansen's works.

No, the racks can be cascaded, forming more than the 2.5" strips.. (a 5", 7.5", 10", etc... in 2.5" multiples.)

Umm... what's wrong with THIS forum? Why split the community any more than it already is?
