The only thing that I wonder about is why you guys choose metal as a base. I would be worried about wires coming uncrimped (/sp) and then shorting out on it.

The chassis is not grounded as per the rules, so it would take both a positive wire and a ground wire to both come loose and to both contact the metal to cause a problem.

Our wires are tied so tightly that this would be almost impossible anyways.

Yes, we have 4 end blocks.

Where does your backup battery sit?

Yes we have allowed enough room for the cables. the robot extends 3 inches past the end of the plate.

The backup battery mounts to a bracket on the side near the rc.... not in this picture.

We just have 3 speed controlers and 2 spikes right now.. I don't understand how you guys can use 8 or 10??

If you're running your drive train with 2 CIMs on each side, that uses up the 4 victors that came in the kit. Then another for any other motors that you'll need for your manipulator or lift system or whatever other mechanism. Also, some teams install a spare 1 or 2 in case one gets smoked during a match it can easily be rewired to a fresh one.

For my drive train don't I need 2 victors for just 2 CIMs? Am I wrong? Why would I need 4?? And we are having 1 for our lifting actuator.. So that shows three? I am just lost for 2 CIMs for 4??

And also it is a good idea to just replace it.. I think I will use it..

[beemgruem]

Oh never mind Sorry about my bad english.. We are using 2 omni wheels so we are actually connected just 2 of our wheels to CIMs.. So that is okay now

[Bochek]

What you are missing that will help explain what your reading, is that we have 4 CIM's powering our drive train, that uses 4 victors, we also have 4 victors for the manipulator. Notice the lack of pneumatics and spikes?

Rule of thumb: If it's a motor, it uses a Victor. If it's a piston (or a motor used like a piston), it uses a spike. So, two CIMs per side of the drive, that's four victors. I guess they have four motors for a hurdling device.

In your case, as described in this post, yes, you only need three. Add one per motor added later. (e.g. adding two CIMs to the drive takes your total to five.)

also, if you look carefully you can see that it is sitting on our digital scale.

9.7lbs (includes everything except a battery.

I'm assuming your master breaker is also at the far end there.

You've got a fairly clean wiring job there. It looks very nice.

[AJ R]

It looks really nice. Someone must have spent a lot of time making the wires look neat.
It looks like the two maxi blocks are connected through one another. Is this right? It if is, then according to R50, there has to be another 6 awg wire connecting it to the Rockwell distribution block.

<R50> The 12V battery, the main 120-amp circuit breaker, the power distribution block, and circuit
breaker distribution panels shall be connected as shown in the 2008 Power Distribution
Diagram. In particular: The battery must be connected to the ROBOT power system through the use of the
Anderson Power Products (APP) connector.  The APP connector must be attached to the battery with either the copper lugs provided
in the FCI Burndy Bag or appropriate crimp-on lug connectors. The battery terminals and the connecting lugs must be insulated with shrink tubing
and/or electrical tape.  The main 120-amp circuit breaker must be directly connected to the hot (+) leg of the
ROBOT-side APP connector. Only one 120 amp main circuit breaker is allowed. This
breaker must not be bypassed.  The power distribution block must be directly connected to the APP connector and main
120-amp circuit breaker. No other loads may be connected to the main 120-amp circuit
breaker.  All circuit breaker distribution panels must be connected directly to the power
distribution block. No intermediate connections are permitted. Additional lengths of #6 red and #6 black wire may be used to reach the panels as
needed to make the above connections. Circuit breakers must be accessible for inspection at each FIRST Robotics Competition
event.

Oh, and why do you need eight 40 amp loads?

What do you need eight speed controllers for? We have half that!

We will require 10....
