But hey!

There may be the CIMs on steroids again (without the raising-Core Body Temperature effect of course and BALCO and Team Phonak)

Here's our old Cannon Bot design which we are replacing the drive system with our new mecanum drive train design. We're just now CNCing the transmission plates and writing a basic code - vector only, no rotation. It'll be around X-mas by the time we're done.

We would if we had money.

Thats what we've been trying to convince our mentors about, but they don't want to let us.

Also, if in the first week of build we all agree on a design that turns out to be the absolute worst possible design and we come in the second week and try to change it, our mentor wouldn't let us. He would only let us change it after various prototypes and showing him multiple times how inefficient it would be to utilize that design.

Sounds like fun! Our team would do anything for a CNC milling machine (at least I would). I don't think our team has had a chance to do any serious programing to ours yet; right now it is a safety hazard and needs to be cleaned up.

Keep us posted!

Our programmer is more than eager to program a holonomic robot,
and we weren't sure if mechanums would give us the same ability.

Holonomic (omni) and mecanum give the same abilities, but the mecanums are easier to put on a kitbot. Also, omni's can be really easy to push around/spin; mecanums are much harder.

We've started a program that will just read in ch3 and ch4 from the vex transmitter for simple FWD/BWD/LFT/RT and those angles between, but at some point we'll work in some rotation code - which is the tough part. We've made our class an ROP class which came with some initial funding - enough for a CNC Jr., BandSaw, Sander, Cordless Drills, trailer, some metal and of course a set of Mercanums to play with. The CNC really opens up some possibilities and raises just as many issues. It's easy to get into a mindset that the CNC can make anything you want - when in reality there is still a lot of work and time that goes into making each part.

You're just a bit faster than us slow pokes.http://www.travisusd.k12.ca.us/vande...s/DSC02034.jpg Here's our old Cannon Bot design which we are replacing the drive system with our new mecanum drive train design.

Speaking of Canon Bots...
ours isn't mecanum though :(
just a suggestion to team 1726, once you go CO2, you never go back. You get hundreds of shots before you have to refill your tank.
