Forgot to mention. The video didn't have captions regarding our autonomous modes.

We have the following:

2 Ball Hot
1 Ball Hot (left or right)
1 Ball Hot, 1 Ball Cold (We ran this at San Diego)

Hmm, how does that auto-adjusting active intake work? Is the whole thing (motor and all) on a slide? That's pretty sweet.

Yup, the whole assembly is spring tensioned.

Another great robot from Hall Of Fame Team 1538. I know that we are looking forward to match 145 where we get to play another qualification match with you; that makes one qual match together at each event this year!

I always love your wiring. Do you have any 2014 electrical pictures?

What are the benefits of using hardware to hold the elex pieces down to the bellypan? What hardware do you use, and why did you start using it?

Well, the electrical components do have clearance holes for the hardware we're using...

It allows us to align all of our hardware in CAD and ensure that the electronics are robustly fastened to the baseplate. We typically use 1/4-28 on 1/8" plate. For the Talons, we use #10-32. For the Digital Sidecar and Spike Relays, we use #6-32.

All of our fasteners holding down electronics are Nylon screws to ensure that there is proper frame isolation. Teams have had issues using shielded DB-37 cables and DB-25 cables and didn't realize that the shield was touching metal fasteners, creating a short between chassis and potentially ground/power.

Not to mention, using Nylon screws is significantly lighter than using your typical metal fastener in this application.
