1458's board

We had three people working on this board and everyone that was doing it hadn't done it on the actually robot before. Does anyone see anything that we should fix

There's two more victors out of site under the other two (connected by VEX things)

and there is 4 spikes that aren't currently wired that are under the fuse board.

Re: 1458's board

You have to be able to see the lights of the Robot Controller from three feet in front of the robot, and as far as I can tell you can't, but that might just be the angle of the picture. Also you will need to access the programming and tether ports on the controller. Also the reset and program buttons are at bottom and very hard reach.
Other than that, it all looks legal, as long as the wire sizes are correct.
You may find that you want to have better access to the bottom victors, for debugging and if one of them dies.

Thanks for the response

The RC is facing the front of the robot so I don't think that'll be a problem

we tested the tether and programming port placement and it was a squeeze but it worked, and we have some 90 degree angles lieing around somewhere that we might end up using

we have a remote reset and programming buttons

I kind of just typed this up so I could go of everything you brought up and make sure that I'm not lieing to myself in my head

Re: 1458's board

I'd like to see some protection against the aluminum edge rubbing through the big red wire to the breaker panel (lower left of photo).

I'm not a big fan of vertical mounting for the RC, but I also see nothing wrong with it.

How are those bottom Victors mounted - that is, why can I see screw heads for the wires (and the wires/yellow connectors), a bit "above" (in the photo) the screw heads for the victors I can see completely? I've attached a photo for clarity - the red arrows point to what I'm wondering about. If they were mounted upside down, I shouldn't be able to see that, and it they're mounted right side up, there's something I am missing...

Other than that, nice work!

Don

Re: 1458's board

Andy,
Not bad. As Kitmor has pointed out, having the programming and tether ports facing the outside of the robot will help in the future. Once you tear one of these off the RC main board, you are done. Many teams will place the tether near the outside of the robot for one particular reason. When running tethered all you need to is tug on the tether (don't use the mounting screws) and the robot will stop. This is a great feature when testing the robot software.
Don is right on the sharp edge for the positive lead. You can add tape to either the wire or the edge or both. Better safe than sorry.
On the speed controllers, a good hint is to use the ring terminals for the fans as you have done, but turn them upside down and underneath the main power input. This keeps them out of the way when working on the controllers. As you have them, one is crossing the other. Remember that when the robot power is turned on, those two terminals are tied right back to the battery through the breakers. A short on the battery anywhere is a bad thing.
The need to be able to see the RC helps when you are working on the robot and for field personnel who are trying to get you working on the field. The lights on the RC indicate a variety of functions you might need to look at.
One last thing, It is better to have the main breaker where you can reach it and the breaker panel in a protected area. I might be inclined to switch those two.

Re: 1458's board

Thank you for your helpful responses, I've already taped up the edge the wire a bit more and I've attached a picture of the victor setup
