I like it for the most part, but I have a problem: the main power switch. Please, make sure that it is easily accessible or you are going to have a rough first event when you have to find a suitable place for it.

Love all the strain relief, especially on the cable going to the cRio Ethernet.

Hope there is a label sheet close by that tells you want all the numbers mean.

What is your cRio mounted to? Remember, it needs to be insulated from the frame!

The entire setup does look very nice, keep up the good work!

Underneath the cRIO we have a sheet of lexan inbetween the frame and the cRIO.

Oh. Electronics take space. Forgot about that... At the moment all our electronics are supposed to fit into a cube the size of our minibot...:yikes:

Hopefully the screws (if any) are not capable of conducting current from the robot's aluminum base plate to the cRIO's threaded holes. (Even if they are, it's easily fixable.)

I don't think that main power switch (120 A breaker) is particularly inaccessible from the exterior of the robot. Although a full determination will depend on what goes on top, as it stands now, if I were inspecting it, I'd pass that aspect of it without question.

Plastic screws ;)

Lets just say our breaker needed to be in the back because there will be lots of clearance there as opposed to the front.

In my experience, you then have a different definition of what some inspectors deem "easily accessible."

If anything, the breaker would fit by our bumper mounts up on the frame.

Though, we've never had an issue with the breaker during inspection (New York City Regional) when our breaker has been in less accesibile parts.

Last year we had our breaker under our shielding with the only way to access it being a 4 inch hole in the shields. At inspection at KC we passed. At QCR we were told to cut the hole larger, but still passed. That one is way more accessible than ours was so they should be fine.

A piece of velcro covering the full bottom of the cRio works as well.

Entirely possible, though I'm curious as to what you think is impairing accessibility.

(I read that rule as referring to easy accessibility of the off switch and on lever by a person's unaided, unprotected hand. Seeing as the entire top of the robot is currently uncovered, what am I missing?)
