Re: HELP: Voltage Drop
I would say the most likely issue is using 6 pneumatic wheels without a drop center. That's a whole lot of scrub when you try to turn, and that will eat your battery like you wouldn't believe.

Re: New radio
Do you have your radio powered from the VRM? According to the user manual (http://www.ctr-electronics.com/VRM%20User's%20Guide.pdf), it should work all the way down to 5V input. If your powering it...

Re: Can we fill our wheels with water?
Note that in Ultimate Ascent, there was a similar blue box under R8 (which is the same as R9 this year) which listed hydraulic fluid, and was the basis for the ruling - the description is the...

Re: Can we fill our wheels with water?
Guys, this seems like a serious question, and a lot of these answers really aren't helping.
Look at the blue box under R9. The blue box provides "examples of items that will violate R9". In that...

That's the difficult part. R21-C states:
So in cutting them, you have to end up with a round, petal, or hex cross section for the pool noodles. Cutting them in half, or square, etc would not be...

Re: Bumpers
Keep in mind that pool noodles are not really a precision crafted part. One's that are sold as 2.5" may not actually be exactly 2.5" - I've seen variation of them up to 1/4". 3 1/4" diameter,...

Re: Charged system during inspection?
Please note T18:
So, start inspection with your pneumatics dumped. When the inspector looks at the frame perimeter, explain that the pneumatics holds arm in place, and your inspector will say "ok,...

Re: Question about frame perimeter and wheels
At least the times my team has done WCD, we've been able to do it with direct drive from the gearbox, eliminating the need for chains or belts. Then again, we're doing direct drive this year, but...

Re: Are these bumpers illegal?
I see two big legality issues in this picture (which isn't to say there aren't more that I don't see).
First, your bumpers are not supported on the ends- see R26. That means both ends of each...

Re: Legality of third party fans
That would be a good way to clean out the parts closets for a hundred teams or so! And if you build it, maybe you can get your local MC to ride it around during competition!

Re: Question about frame perimeter and wheels
Any part of your robot, including the wheels, affects the frame perimeter.. If your frame itself is 30x30, and your wheels stick out more, then you are too big.. Also keep in mind that the frame...

Re: Purpose of off-board Vent Plug?
Are we looking at the same picture? Figured 4-16 and 4-17 have the vent valve located on a T, with the other sides going to the compressor and across to the robot. It does vent to atmosphere.
