where you using the Servo Example. vi? Because I need some help on that

I'm another programer from 1626 and yes we were using the Servo Example.vi, what do you need help with? we would be happy to help

so far our robot is able to rotate to target.
is there anything else that the servo should be able to do?
is the camera itself supposed to move?

Unless you mean the camera is moved by the servos, then no the camera does not move. Actually, depending on where you place the camera, you probably need no servos at all to aim the camera.

ok thanks, then Im all set. But I do have one more question for the electrical board. Do you have any suggestions on what type of material I should use? Right now we are on wood, but we also bought Lexan. Is it a good idea to mount everything on Lexan? And do you have any suggestions to make the electrical board compact and clean (as in not messy with length wires) ?

Generally, we mount all of our speed controllers (mostly Victors but some Jaguars) on perforated aluminum mounted in the frame. We generally use folded sheet metal chassis, so we would make the bottom of about half of it out of perforated aluminum and mount everything on that. The cRio should be mounted on lexan or wood to be electrically isolated, but nothing else needs to be isolated. I'll see if I can find pics of it on old robots...

If we didn't have a ball manipulator system in the middle of this robot, we would've put a sheet of perforated aluminum in the middle area and put all of the Jaguars there.

A direct answer to your question is to use perforated aluminum with polycarb for the cRio.

Our website is being redone so I can't find any older pics at this time, but in most of the robots we had a rectangle with two side rails (inner and outer, basic 6WD chassis) out of folded sheet metal, with a divider in the middle. In the middle, one half would have a sheet of perforated aluminum on which all of the electrical components would be located, the other half would have the battery, drive motors, and some bot-specific items. We used this basic design from 2006-2008, and something similar but welded in 2005.

Thank you for the pics, they were really helpful, I am planning to mount the whole electrical board on lexan actually.
