Are we the only team going for the empty cell…??
What are those black connectors?
It looks like the aluminum tube frame system we used this year. Very light, strong, and easy to take apart if you modify something (not that we would ever do that…)
Is there a site or something I can read up on for this stuff?
Here http://www.eztube.com/ is the material we used. It isn’t very fancy, but we are pleased with it.
Team 456 - sorry to hijack your thread for a frame discussion. Is that the material you used? What did you think of it?
Nice robot, by the way. 
It is 80/20 QuickFrame with associated connectors. We have used it extensively since 2006. Just go to the 8020.net website and look at their QuickFrame lineup. The connectors come in all sorts, corners, Tees, etc. and in black or gray. The QuickFrame tubing is fairly light (~.25/ft) and annodized so it looks better than regular extruded box tubing. It has longitudinal ribbing inside that grips the connectors so you just cut it on a miter saw and hammer the plastic connector in with a rubber mallet. Otherwise it is basically pretty similar to thin wall (1/16") aluminum box tubing. The weight of the connectors can add up though. For extra strength we add rivets here and there on the connectors as needed. Works great!
I am surprised the 80/20 QuickFrame isn’t more popular in FIRST than it is. It is half the weight of 1010 T-Slot so many teams are so fond of. The QuickFrame also interfaces/connects nicely with the 10 Series if you say wanted to use the 10 Series on your frame/chassis and the lighter box tubing on your upper structure. 80/20 gives all FIRST teams a huge discount on all their stuff so we can actually buy the QuickFrame tubing cheaper than we can buy regular thin walled 1" 6061 AL box tubing. You can always just use the tubing as you would regular box tubing without using the plastic connectors and just weld it up, bolt it, or whatever you want. We’ve done that too over the years.
We used up over 200 feet of the QuickFrame tubing this year alone between the prototypes, practice bot, and the bot as shipped.
Wow, that looks EXACTLY like the same concept I came up with on our robot for opening and closing a gate. It’s awesome to see that other teams can keep it simple by transfering motion from one device. I have seen so many other teams that use a motor to lift/move a gate, and another to dump/shoot the balls. More things to break like that…
Either way, it’s cool to see another team think like us.
ye we decided to build it as simple as possible…and we had to save all our motors for something else…
