Re: Need help programming arduino

There are a number of tutorials available on Sparkfun. I'm not sure if they meet your needs. If you have a specific question, check out the Arduino website or post a question on Stack Exchange.

Photo ID rules

It says we can't use driver's licenses from certain states for our photo IDs on the security clearance form. However, I read that the TSA is accepting driver's licenses from all non-compliant states. Is NASA under a different set of guidelines? Also, do we have to present both ID cards when we arriv...

Re: torpedos for equipment recovery?

I'm not sure, but I believe there's a rule somewhere that says parts (which the exception of certain sensors) have to be hard-mounted to the robot frame.

Re: Waterproofing power distribution

If you're talking about connection from wire to enclosure, I would look at a commercial waterproof connector like WetMate or Bulgin. If you have two wires spliced together in water, my team typically solders, wraps in heat shrink, then seals in epoxy (in that order).

Re: Is there a standard mission layout?

I don't think it's an arc. I think that means any prop is no more than 8 meters from the pool wall. I would do sqrt(4.8^2+8^2)+3 meters then add on a bit for wiggle room. I would say about 14 meters. When in doubt, add more tether. The tether person can generally move around a bit on the surface as ...

Re: Camera System Set Up

My team uses two different solutions depending on whether the cameras are analog or digital. For analog, we basically use your option two. That's probably the easiest. The only difference is we use RCA jacks, not BNC. If you're using digital cameras, there's another way. My team has a PC onboard the...

Re: Is there a standard mission layout?

All the layouts are the same as each other. However, there is no way of knowing what that arrangement is before you arrive at the competition site. Your best strategy is to be prepared for anything. One thing to note is that there will be several mission runs going simultaneously in different portio...

Re: Handbooks

The MATE website is terrible. Some days, every link gets you the homepage. This has been an ongoing issue for a few months. Just try again tomorrow.

Re: Monitor Power

I think generally monitors and surface side laptops are run off a standard power strip.

Re: Size Restrictions

What about the 85 cm size restriction? Is that also based on a circle of that diameter? Or is that based on the single longest dimension?
