Go to Post Finish... what an interesting concept. I'm still hoping to do that to our 2003 bot. - Joshua May [more]

Re: Wheelless Robot?

I take issue with some of your points:

Sure you might be able to shoot three 3 pointers in autonomous, maybe feed into an allied robot if you're designed for that. How much weight do you really save though for not moving? Maybe 10-15 lbs for no wheels, gearboxes nor motors.

Funneling shots are a good idea but you will be subservient to allied robots in qualification matches to get them to you. I'm not designing a 'colored disc handoff' device so you're going to have to catch them from me at the top of the tower which I may or may not be designed to do.

I will literally bake a batch of cookies if anyone can pull this off in conjunction with your first point. Remember that you have to actually climb the pyramid, arrive in the proper orientation, then transport discs from wherever your allies shoot them in your body, orient them properly and and shoot them back out -- with the same shooter that was angled at shooting from the ground. By its self it is a lofty objective and a very interesting one. But I think you'll have to choose this or the first one. Raising a net to catch allied colored discs is an absolute must if you choose not to move in the match but remember you are reducing your allied scoring potential if they have to spend time scoring colored for you instead of by themselves for eliminations.

Think about it: If you can drive across the field to pick up four colored discs you can score 20 additional points by yourself. If your ally spends its cycle time picking up those discs and scoring into you when it could be scoring white discs for 12 pts, the net value of that trip is only 8 pts. Sure it's worth it but it isn't the full face value of the discs. This will probably not be a concern in qualification matches where few robots will be able to reliably score colored discs but in eliminations, if I could score colored discs without your help, I wouldn't pick this robot. Interestingly enough, this could lead to a 4th or 5th alliance powering their way to the finals with a robot like this in the lead or first pick.

Remember suspending in 2010? And how it was so difficult because it's hard to predict how other robots will work? Unless you build me a system that can hook onto my belay points it won't work with my robot. Furthermore, I don't think I'd trust another robot to lift us up, especially if it was doing any bumping into anything. Also, unless you occupy a significant amount of space above Level 3 (ie you have to be above the PYRAMID GOAL) then you won't be able to lift a lot of robots into level 3.


That said, I think a robot that does this, if executed properly could win a regional as the second or third seed: You might get screwed over in quals if you have an alliance unable to score into you. Also, if you choose to go for this I'd prioritize the auto shooter over the 'score into me and we'll score in the top goal' shooter. Considering the top sort in seeding behind WLT is auto score, being able to score in auto is a top objective. Also the white disc pyramid scoring is incredibly hard to implement.
