Hello everyone! We would like to reveal our robot for worlds. We shipped out today, so we figured now would be a good time to do it. This is our team’s first and second years, and we have learned a lot. Our team is excited to learn and compete at worlds! Our robot, The Rebel, is a scooper type robot, that scores backwards. It also has a strong descore. Our current unofficial high-score for drivers skills is 240, but we expect a higher score since our latest changes.
Hope everyone enjoys, good luck at Worlds!

since you’re a back dumper, you don’t need a 7:1 lift ratio. 5:1 should suffice.
Descorer deployment and descoring in general should be fast, too. Our descorer deploys in half a second and can descore an entire trough in less than a second. You’re wasting valuable time if your robot is just sitting still, waiting for the descorer to deploy.
An entire trough full of sacks in less than a second? That sounds like an exaggeration to me. Do you expand across the entire 33" width of a trough, or do you have a super-fast holonomic drive that can sweep through the width of the trough while you descore?
We actually have used 1:5 most of the season, but found that we were picking up more than what we could really lift, and started burning out motors. The 1:7 has allowed us to get larger dumps, and the lift time hasn’t really been affected actually. The descore was also on a 1:5, but again, the lift time really wasn’t affected much. Plus, that arm is only on one motor, and it would pretty much kill it self.
I feel like if you had put your descorer on your arm, then you could have used that extra motor for the arm, but that might be a bit too much of a change, since there are only 8 days until worlds.
1200B had a simalir design (actually it looks like you have a duplicate of 1200F) but 1200B used their shovel to descore. Here is a video of them doing that: http://youtu.be/CaPt9pQXxIQ?t=1m42s
Very nice robot though! Look forward to playing with/against you at Worlds!
My god. That is very similar. Its amazing how teams can independently develop the same concept. I see what you are saying about quicker in that, but I must say. We get quite a bit more in single dumps, so I’d say it evens out.
Nice robot, it’s good to see other simple lexan trays (much like ours). It sees like the general trend as champs approaches is towards roller intakes. I was just wondering why you are unable to descore using your tray? It seems like it would be a simple matter of inserting the tray backwards into the trough and driving backwards.
The only difficultly i see is if the flange on your tray might interfere, however we have a much larger (2") flange and can descore with little difficulty. If you were able to descore like that then you would be able to remove an entire mechanism, making your robot lighter, and putting more motors on your drive.
Thanks for your post, and trust me, we tried our hardest to. The way our bends and angles worked with the arm in relation to the trough just didn’t work out(I’m not sure if we’ve actually tried with our current scoop) But wouldn’t that be a pleasant surprise at worlds if we found out we could eh? We tried several other descorers this past week, but because our chassis is rather light, the rake descore, and roller descore pulled our wheels off the ground -.-! We really wish we saved another motor or two for our drive train. Who knows, maybe at worlds we can find a work around and get a few fixes in.
Haha yes. That would be bad.
Also, it was brought to my attention that my comment about my own descorer made me look like an ******* (wtf, it censored this? butt hole). I apologize for this, since that was not my intent.
