Wow... That is still VERY nice

Good job!!!!!!!!!!

P.S. I love the zip-tie hinges!!!

[Andrew Blair]

I like the Chevy symbol on the battery box. Very nice!

[BlackRoboDragon]

Wow, I'm not really very good with electrics, but this looks good. Looks nice and orderly, along with well planned.

[Nuttyman54]

better than ours, that's for sure!

[Lisa Perez]

Very impressive. How much does it weigh?

[nehalita]

I really like this. I think some things aren't very accessible but overall, it is a very clean and compact and nice design. Nice job.

I like it.. but that bend on the positive battery cable is scaring me a bit.. what's wrong with trimming it down? That can't be good for the wire.

[Chriszuma]

Yeah, my board looked really nice too... until I started with the PWMs...

[Josh Hambright]

I always enjoy seeing what you guys come up with for your robots, and especialy to look on in awe of your electrical wiring, once again i am not disapointed!

[keagara]

i like the board but itl looke kinda heavy

[Justin_302]

looks good, but is it safe? All that aluminum around electronics....i would be worried about arching

[Jimmy Holmes]

You are right, we will look at that red power cable....it could be shorter.

The weight is around 13 lbs. We know that sounds heavy but we have incorporated the battery holding system within the electrical box. Which means we didn't have to build it anywhere else.

The back rail of the box also serves as the rearmost cross-member of the drive train frame. The electrical box actually sits low between the frame rails to help with CG. With the battery,switch and breaker so close to one another no other #6 wire is required. We just have to run the sensor cables and power wires throughout the robot which should not be very much more. All of the power wires are pretty short runs.

It is a tight squeeze in some places but doable. We will try to keep everything neat and labeled.

All of the speed controls are mounted on polycarb. We will wrap any wire bundles that could rub against the aluminum with wire loom or something like that. It is a good point and always should be considered when building boxes such as this. You should try to keep the wires from rubbing against any sharp edges.

12VDC isn't nearly enough to cause any arcing. Its not even enough to pass through your body (Don't try this - but you can safely put both dry hands across a 12V battery with no issues). The issue with 12V is that there is so much current available in the battery, that if something metal (wrench, watch on someone's arm, etc) shorts it out, an incredible amount of current will flow (in the hundreds of amps), causing it to get extremely hot.

Wow, it looks like it came out of a tank. Nice job, like the wire runs and that all the controllers are marked.
