sorry, i knida pulled two completely random trains of thought into that comment. (me brain works not today) the arms are one thing - the reason that getting to the ramp first would work is becauseteam 45 uses tracks, and tracks don't conform to the ramp. If they come up enought to have part of their drive train sticking up over the top of the ramp but not all the way up, and someone hits them at that moment, then you would literally be pushing up on their robot. that would reduce the normal force needed for traction and make them easily stopped.

of course, the chance that this would happen during autonomous mode is extremely small. It was just an idea.

I know a robot that can get them off the top tof the bridge :cool:. hehehe

Oh i'm sure thats a wonderful robot and that most conventional king of the hill robots won't stand a chance against it. Kudos to the technokats for that. Under those arms are probably motor assemblys that have wheels forced into the ground which are powered. My team had a design like that but we opted against it. So you can't turn it, you probably can't even push it, or get past it other than limboing under the bar. So how do you propose getting by it?

Well its pretty simple actually, you just stick an arm under its wing in that nice areaunder it and.... lift! Yeah my teams arm is strong enough to lift a robot, so while we're not allowed to remove you from the ground, you're not going to have any traction while we get tons!, so our two wheel drive boy can push you right off the top and down the other side. :rolleyes:

I just love our arm!

2 wheel drive is deffinately the way to go. we've been 2 wheel drive ever since 2001 and its worked very well in all cases. nice traction because you can focus weight just for 2 wheels, and then if you pick up part of a robot with an arm (which we do have as well) you could add a lot of traction. or you can do what we do this year and be able to shift your center of gravity with the arm

Team 71 last year did nothing but crawl across the field the whole match, and look what happen to them...Well wildstang and Technokats had them beat at MMR but just had a few bad breaks, but still.

Too the Technokats, you did a wonderful job as always. I respect your team greatly.

There are 2 possible ramp-doms, the wall-dom exemplified by the Kats who really on their traction to keep them on the ramp. The other is the wedge-dom(team 179) whos bot doesn't allow you to push it directly. They both have weaknesses because you could push the wall-dom but a bot could run over the wedge-dom. At this point I'd put my money on the Kats because their drive-trains are always on the leading edge.

As for the best kind of drivetrain, it depends on your strategy but I dislike unpowered wheels, IE 2 wheel drive or castors. The reason being is you lose effictive mass. Unpowered wheels bear weight, weight that would otherwise be used to increase your traction. So instead of your bots drivewheels being pushed down with 130lbs of force there being pushed down by less. Which means you lose pushing power.

Only one problem with this, they have used every drive motor that has any power at all.

There is another way :p :D

globe motors and window motors are powered too, if you gear the globe right it can be very useful. having 2 wheel drive doesn't mean you have unpowered wheels on the bot, you could have 2 skids in the front or back

Tyler Olds 18-02-2003 09:19

do you have a picture with your wings up?? or more or less could you please post a pic with yoru wings up??? I would greatly appreciate it.

Yet another way

Oh there is another way. Oh my oh my, there is definately another way. I look forward to seeing them at MMR, yes I do.

First I must say...very, very impressive robot. I still, however, am still skeptical of this strategy. First, let's just assume that you are immovable. Those have to be incredible rigid wings to stand the punishment of two robots ramming into them for 1:45. Now, you may be able to hold in most of the qualification matches. But, when you are paired against two good robots in the elims, my money is definitely on the two robots hitting you. All I can say is that I hope you have plenty of spare parts, and one heck of a pit crew.

You've never even seen it move.

This is why I think scouting based on pictures, or even formulating strategy is all but pointless. Until you can get in close and really discern how mechanisms work, see how the drivers perform, and get an idea of what other robots will be around at the time, you'll have limited success with formulating a strategy.

Clark Gilbert 18-02-2003 12:33

Yah
 
We know they will be taking quite a beating and that's one reason for the angled brace on the back of the wing. One thing you can't really tell either is that these arms are filled with a really rigid foam that makes the arms very stiff. The entire wing assembly weighs about 44-46 lbs.


Look familar?


Joe3 18-02-2003 12:41

How easliy does the foam compress, and what else do you have on the front of the wing?

Dan-o 18-02-2003 13:02

Looks painful
 
I see a resemblance in the Kats robot this year to MOEv2002. Let me tell you a couple things about last year (I was only there during the off-season).

Our strategy worked fairly well for bots without a lot of torque, However, the alliances that beat us were comprised of two major pushers. I feel that you guys have an added vulnerability because you sit atop an almost frictionless pad.

Another thing, you guys will only be able to score 25 points by yourself, while you prevent other bots from scoring. Truthfully, I don't think you will be seeded, however you will be in one of the top few alliances as a partner.

One more before I finish, repairing MOE between every match last year was a monstrous task. If you can do it, more power to you. Good luck in your efforts.

GO MOE!!
