Alan,
Some of the applications of glue I have seen give me nightmares.

Re: "The Little Things" - Helpful hints for all
 

Has anyone ever had problems with velcroing (or wire-tying) electronics like motor controllers? We don't do it, but I've always been sketchy on the explanation.

Re: "The Little Things" - Helpful hints for all
 

I've always consider hot glue to be okay. Similar to the adhesive on velcro is that still allowed? I have also seen teams use clear nail polish to hold PWM cables into speed controllers would that also be illegal?

When cutting or drilling parts that are already on the robot, make sure to protect your electronics from metal shavings and the like.
We have a blanket that we throw over our electronics when necessary, but when possible, we take the part off the robot to machine it first.

Yes. We think we had some problem with that. "The Little Things" must have been falling in :)

Re: "The Little Things" - Helpful hints for all
 

We've been velcroing just about everything on the control board for as long as I can remember, and we haven't had any problems so far. However, don't velcro the main breaker. There isn't enough surface area on the bottom for velcro to effectively hold it in place, and it's too important to have flopping around in there.

As for things that I'd suggest, I've got:
-For Chairman's, always have at least one boy and one girl on the presentation team. Trust me on this one.

-Also for Chairman's, practice the presentation ridiculously slow in front of the entire team. In addition to making you look like fools, it serves a few purposes: giving the presenters practice under pressure, making the presenters used to going slowly, and giving the entire team at least a basic understanding of what the Chairman's submission contains. Which leads into my next one...

-Everyone on the team should be able to talk to the judges about the team's outreach. Without fail, judges always come by when the spokespeople are in the bathroom, so others should be able to cover until they're back.

-In terms of outreach events, I think Karthik said it best when he said that you should find that "pie in the sky" and MAKE IT HAPPEN. That's where amazing Chairman's submissions come from--that crazy idea that worked.

My take on the Glue vs No Glue debate :D

Re: "The Little Things" - Helpful hints for all
 

My opinion is that the adhesive on velcro is not considered "glue" for this purpose, it fits in the same group as labels. Nail polish on the other hand may be considered more than adhesive backed materials.
We used velcro in the past but abandoned it in favor of tie wraps. They are cheaper, easier to use and just as fast to replace components.
As a side note, the Q&A is the only place to get definitive answers to rules questions. My posts are my interpretation of the rules. I have been wrong before.

Re: "The Little Things" - Helpful hints for all
 

Yes. Make sure your whole team knows about your outreach and can speak semi-intelligently about it.

However, I have heard stories from several years-worth of my students at different regionals saying judges have "interviewed" them in the bathrooms - so you should always be prepared to answer questions about your team!

As a corollary, make sure your non-robot students have a basic understanding of your robot's functionality. Our non-engineering captain last year claimed to the judges that everyone on the team was instructed on how the robot functioned even if, like him, they didn't work on it. They called his bluff and made him explain the systems. He did a good job!

Re: "The Little Things" - Helpful hints for all
 

I can cite many instances of an all-male or all-female presentation team winning a Chairman's Award (at both Regional and World Championship levels).

Re: "The Little Things" - Helpful hints for all
 

Al, how would you feel about using nail polish as a marking to help quickly ID which direction the connector goes in and where? Reason - Nail polish comes in a lot of colors, is pretty cheap, readily available. It COULD be considered adhesive holding the connector in.

(Obviously, if I plan on doing this and there is ambiguity in the rules I will post in Q&A during season. Just trying to get a bearing here)

Re: "The Little Things" - Helpful hints for all
 

The trouble is the Q&A often creates more ambiguity than they resolve.

"To Glue or Not To Glue"...as an electrical engineer I don't see any problem using regular hot glue to stick PWM wire to Victor/Talon or any controller. Though I think this is not tampering (no cutting, damaging or enhancing the functionality to take advantage, not a source for safety concern etc.), but the inspector may not have the same opinion. We avoid this situation by using hot glue or electrical tape to secure the wire to the robot frame, a little before it reaches the motor controller. Typically we use velcro to secure the motor controllers and the power wires (both in and out) are secured by zip tie. The motor controllers don't move as much as the loose PWM wires. Then we use electrical tape to fasten the PWM wire to the fan without blocking the air circulation. On the other end, pins on the side car will keep them secured.

That is awesome.
