Well, theoretical speed is one thing, but actual speed would be a little more relevant.

We can get to the goals in about 3 seconds (we normally go about 6 fps) but for some matches at MMR we geared TOBOR V up to get the goals in two seocnds (going at 12 fps).

Dan-
Even though i probably saw the match, i'd like to watch it again, but i don't have real player.

to All-
Does anyone know where i can get real player from? whenever i search, i get some real one player, which apparently costs money, hence the FREE 14 day trial. i don't want to pay (seeing as i have no money ), and all i want is the original real player so i can watch the movie. thanks in advance.

Time to goals

At the West Michigan Regional, our average time to the goals was 2.75 s when we were going for two goals. Unfortunately, our goal latch mechanism wasn't working very well so we lost the goals a number of times even though we got there first.

The good news is that we've already made a fix that works wonderfully so we shouldn't have any goal latching problems at nationals.

Can't wait for Disney!

I see that speed is one thing but to be able to grab the goal with as much speed is another.


We took alot of goals away from teams because they were slow on grabbing it.

We were quick but we were faster grabing the goal and running with it.

the fastest team might of beat us to the goal but the time it took us to get there and pull away the other team had no chance for it.

And if they did grab it we pulled them away very quickly.

well

That is true, so actually, we totally avoided the "goal latching device" completely

We rely on our quickness to get to and smack the goals out of the way preventing other grabbing mechanisms to be affective. I actually works pretty well and doesn't restrict us from helping and or blocking our alliance partner.

in conclusion BruteForce triunfs once again!

Well since we're letting people know our team tactics, I might as well finish where you left off .

We basically choosed to ignore the goal-handling aspect of the game in the sense of latching on and holding the goal. Now, yes, this does have it's drawbacks, but it also allows us to concentrate on controlling other robots - which is the important part. The team 810 robot is a low guy designed for pushing other robots where we want them to go and controlling other bots. We can switch between wheels and treads on the fly. We spend most of the match on wheels trying to interfere with other robots (like getting in their path so that they can't get out of their homezone, ala team GRR ) Then, when need requires it, we jump up onto treads and push doods around. Thats baiscally what happened that one round I linked you guys to: we were controlling other robots, then during the last few seconds, we went into tread mode and pushed that other poor guy from their scoring position into our scoring position - while he was latched onto the goal. We switched back onto wheels and zipped it out of there back into our homezone, winning the round for us.

This of course is the plan, and as we all know, it doesn't always go according to plan. Contrary to what Steve said before, brute force doesn't always triumph (don't mind him, he's only our team ego ). That round let us go onto the semi-finals, where we lost. As it turns out, we lost mainly because we were hitting TRIBE at the wrong angle. We were trying to move them perpendicular to their drive train, and if they have two goals that just doesn't work no matter HOW much power you have. But thats a driver problem that we have to work on. Don't worry, TRIBE, next time we'll push you from the front so that you will be pushed into our scoring zone

Anyways, thats how our robot works, for all you scouts out there. All that we have to do now is look over the videos and see where our drivers need improving, and we're all set for Nationals.

Now that I've told you how team 810 works, for the scouts, how does everyone else's bot work?

If you have the power this should not have stopped you.

People have try that agaisnt us and they have gone over take a look

http://www.valleytech.k12.ma.us/Robo...ng%20Robot.jpg

this is two goals and a robot Heat wave which is a good team. then we push there teammate and the other goal all at the same time.

this is power.

This is how they planted themself

Well it all depends on the robot's drive train and how they are aligned according to you.

The problem was that we were trying to move TRIBE by essentially going broadside into them. TRIBE was latched onto two goals, one on the front, one on the back. We were trying to move them by pushing them right in the center at 90 degrees to their movement path.


If you try and do this, it all depends on how much surface area they have touching the carpet. If they just have 4 wheel-chair wheels touching the carpet, then yes, this is possible. If they have treads running the lengthwise of their robot, doing something like this becomes a lot harder - no matter HOW much power you have. When trying to push a bot this way, what it basically comes down to is their drive system and how much surface area they have in contact with the ground. Our problem is that we tried to push TRIBE like this more than once. Had our drivers pushed them at an angle, pushed the goal (not their center of balance), or better yet, gotten parallel to them and pushed the goal, theres a strong chance that we would have moved them. Either way - thats why we have videos of the event - to see what we did wrong and improve on it next time.

BTW, that picture didn't work. You sure you have the link right? I'd like to see this bot of yours

2 secs for sure maybe faster

Anyone who's seen the 226 bot may have needed a high speed camera to clear up the blur (Just kidding)

We can hit the center goal in 2 secs every time right now with a slight delay to the outsides but not much since we 4 wheel steer at full speed. The biggest problem we have? We are geared a bit high with a 1 speed tranny and had to make sure the wheels would slip before stalling out the motors. A little bit of work is in order in Florida but the gearing is staying (it's all welded ) and we will enter in any races

This will show you team heat wave had both goals in there in zone. We turn them around and dragged them to our zone then push the third goal with there team mate trying to stop us.

I don't no why the other links didn't work?

ok Dan, it is time to "unleash the EGO"

(now u r in for it!)

ACHEMM...

The reason why dan and i had trouble even in the spot with tribe at colombia was due to the fact that i did aim for the first goal. i don't care about numbers, all i know is that every time that we the drivers were set on getting rid of one of the goals we were always there on time and got the job done no matter the opponent!
I m not saying that there were errors in strategie in some of the matches (achm **dennis**), but once we finished with our side of the deal there was always so much time left that anything could happen. Yes, i m bragging about our speed but only because i m confident beyond all rookie teams, that we the bulls, had the fastest drive system in the tri-state area. this is mainly because we are a drive system and left all the other mechinisms considered being robotic, "IN THE DUST"

yes, but steve, you have to remember something. as Mr. Blumburg explained to me today, even if we do have the fastest drive train, we can't compete on the same level as the other robots. sure, hauppage (358) can't grab a goal either, but they have a really nice pusher, which works extremely well, untill certain people *cough*steve*cough ram into it.

as everyone that's seen our bot knows, we have a piston on top, which never did a single thing. we had plans for it, but we ran outta weight. Well, hopefully at nats, if i can convince my team, i have another idea, which will give us more control over a goal. plus, we won't have that stupid piston on just to add weight. i can't say what this system will do, although i can say that if i can build it, it will work no matter what. it's that simple.
