That’s pretty neat. I saw a robot just like this earlier, but that one does not have obvious mounting points for top secret withholding allowance business…
We’ll be spectating and rooting for y’all Sunday at the Battlefield event. Knock 'em dead!

There can be big impacts when going over the obstacles, they have identified this and made very strong mounts for their pneumatics tanks, which they have subsequently attached with cable ties for impact absorption:)
I’m also big fan of the actuators without any tubing running to them j chillin on the frame.
You sir are one bad motor scooter.
That’s a very nice and elegant design for the intake. Where did you get the mecanum wheels? They don’t look like the ones from AndyMark.
Thanks.
Our priorities this year are:
- robust drivetrain
- intake and low goal scoring
- climbing
- high goal shooting
Our climber development is ongoing, using the practice bot. 6 week build season? Umm, no. We don’t even plan that way anymore. The goal is to climb at our first district competition, and add the high goal shooter by the second, if it makes sense strategically.
Since Triple Helix put our robot in the bag, we have continued developing our climber on our practice bot. Last night, just before the end of our second open bag access period, we made this climb. We have some more tweaking of the hook height, but things are looking good for our first district competition this weekend in Haymarket, Virginia.

Todd…is that Paracord your using?..Be very careful with it…we learned a lot
of good and bad about it last year. Robot looks good though.
Just wanted to make sure that those aren’t the same white, plastic Clippard tanks that were stated to be illegal in Update 14.
Would be quite unfortunate if they were, and you got to competition without planning ahead to swap them out. Just a heads up.
You know that not all white plastic tanks are the Clippard ones, right? The same way that all white cars are made by [insert car company here]
Very much knew that was a possibility. Just wanted to make sure they were aware. Better safe than sorry.
@team2363 apparently I’m not allowed to actively humiliate people who badger us about our white not clippard tanks. I was trying to get some QR codes printed as stickers to put near the tanks so people can be put to ease. Preemptive tip for ya 
How heavy is your climber?
Zebra_Fact_Man: Thanks. We stocked up on tanks from Pneuaire. Company name has since changed.
PayneTrain: We don’t mind. I’d rather have someone point out an issue we already know about - than not point out an issue we don’t know about.
mrmummert: Yes, it is paracord. Have any lessons you’d be willing to share?
Todd…you may or may not remember the issues we had with our winch system last year in which we used paracord.
Kyle can probably fill you in a little on it too. I forget at the moment which type we used (we tried several types) but I recall using the stuff that wasn’t supposed to stretch…well no matter what you do it will stretch some or a lot
depending on what type you use. We found that out the hard way. We had to add a tensioning spring to prevent slack. We found out that it worked well when a constant load was on it. When we had any good amount of slack it would bind up on us or get caught in parts of the winch we had. You guys usually make stuff to closer tolerances than we do so you might not have too much of a problem with it. It also helps to burn the ends a little to help keep it from unraveling.
Over time keeping our winch and arm operating properly slowly became a PIA. That was one of the reasons we changed our robot design that we used for the off season “Rumble” event.
Thanks, Hank. Happily the mechanism with the paracord only has to work once per match. We have lots of weight allowance we could use to replace all the cord with chain, if it came down to it. During the match we plan to wad up the slack cord and wrap it with rubber bands. The theory is that it will deploy without getting hung up. We’ll see, though…
We replaced all our paracord with spectra spearfishing line. The climber works quite nicely, as you can see in this video. Views from onboard the robot, closeup video, and wideview video of our second semi-final match at the Hampton Roads CHS district event. We had 11 scoring climbs at this event.
