Re: Robot ideas
 
any way a robot can have a high torque elevator, ground level. Also it can have an arm folded within this space.

The robot can play as a offensive tube stacker until the last 15 seconds. Then it gets a robot to drive on its elevator, and slowly lifts the elevator to 12"s.

Hovercrafts anyone? :D

Re: Robot ideas
 
i was talking about the bonus points with my dad yesterday, and we came up with this idea.

1. your robot is fairly flat-backed, and about as tall as the sideboards (this is assuming a forklift-style innertube manipulator near the front of back of the robot: something tall, but not very deep).
2. you have a pair of springloaded panels on the back of your bot, such that if you pulled your bot parallel with the sideboards with a couple of feet in between them, you could release them and one would flip out laterally to create a platform, supported on one side by your robot and on the other by the sideboards.
3. the second panel that i was referring to would be attached to your first panel, but in a way that it would funtion as a ramp.

i know the explanation is vague and probably tough to understand since i can't stand here and pantomime everything with my hands. it's also probably deeply flawed in ways i haven't noticed, but i mean this comment as a sort of jumping-off-point, something to get people thinking. take it however, i just thought it warranted at least a mention.

This is interesting...

<G30> ROBOT out of bounds - Any ROBOT that touches any surface outside of the field boundary
will be disabled for the remainder of the period (either AUTONOMOUS or
TELEOPERATED). No penalty points will be assessed.

So I guess you could use one of the side walls to support a platform - you are disabled but not penalized, and your teammates can get the 60 pt bonus.

I'm not sure if it would be allowed, but it is technically legal at this time.

Re: Robot ideas
 
I am really into the idea of getting your robot to stick to the plexy wall.

I am still to read ALL of the rules but has anyone found a rule against it yet?

Re: Robot ideas
 
You could stick to the wall but you wouldn't get any bonus points because you cannot be touching any part of the field or any field element.

Re: Robot ideas
 
The plexi-glass wall between the field and the driver's station is considered a field element therefore if your robot is touching the wall then it is not considered elevated. Don't even think of using tubes to elevate your robot either.

Re: Robot ideas
 
If that's the only rule that applies, I suppose you could park a robot against the wall, then deploy a ramp from it, and have the wall keep it from sliding as the other robot(s) drive on the first, and still get all your bonus points?

Re: Robot ideas
 
Our team had a really funny (both :ahh: and:D ):
have a pair of ramps, extending out _far_ (say 5 ft+) that roll up smaller.
In autonomous, wait a few seconds, then unfurl the ramps. During teleoperated phase, the drivers take out fake martinis and stand around looking funny.
At the end of the match, the other two robots roll up the ramps for 60 points.
Bonus feature: The other team cannot pick up rings from behind you: The ramp is in the way! :D :D

Re: Robot ideas
 
I am sorry if I am going to break anyone’s dreams
BUT
Defensive robots are no help. in the past years they mostly get in your way since they are so engaged with defense, now I am not saying that they are they are not helpful but its allot more efficient to build something average that score onto the low and middle legs since if you have been part of FIRST for at least three years you already have these robots build.

A as a last note lifting robots at the end of the match will probably be useless since most teams will no be able to lift or be lifted they will spend most of they time being in your way so it would be very hard to come back.
Pay more attention to the rule that says if you are on an opponent’s home zone at the end the opponent gets 10 point as a penalty, now wouldn’t it be easier to use a high pushing robot to push your opponents onto your home zone and get the 10 point bonus since FIRST really likes those bumpers and pushing has become a big part of the game.

So reminder
1. Just defense robots are not useful at all
2. to avoid number one build a robot wit an average manipulator that’s able to score on low and middle since its already been done
3. A powerful robot at the end of the match would prove the difference between no bonus points and 10 bonus points, and hey if all three of the opposite alliance is caught that’s 30 points

Sorry my post was so long I hope I made some good points and I was helpful
Good luck in 2007 and look in the past sometimes there is the answer

Re: Robot ideas
 
Wouldn't a team that is building a defensive-oriented robot or low scorer want to sacrifice weight and be 6 ft tall? That way it parks in front of wherever the opposing team is trying to score, and blocks two spiders, and it would just have to push the scoring robot to try and stop it from scoring up high.

while i'm thinking, couldn't said team instead build a 6 ft tall flop bot(so it starts like l, that was ramp shaped (but adjustable,) and then flat, and then fall over at the begining, and then at the end, use pneumatics or something to bring the ramp end down(to fit within the rules), and let the two robots drive on top? ______

Interesting idea. Good defensive technique. But can you actually do that?

Re: Robot ideas
 
I think if your a robot that wants to be picked up, put on the back of your robot a ring shaped exactly like the game piece, then you can be picked up the exact same way another robot picks up the game piece, just heavier.

Re: Robot ideas
 
For those teams planning on manipulating the spoilers/keepers/ringers , it is probably necessary to be able to handel them whether they are flat on the ground, leaning on a playerstation or being handed thru from the player station.

IMHO, the early regionals are going to be in favor of the ramp bots while everyone is still practicing/debugging/completing their robots. But, by the time we get to Atlanta, the stackers will be the dominating forces in finals.

As for how I think finals in this game is going to be played out.....

1st round picks are going to be aggressive stackers.

2nd round picks are going to be any more aggressive stackers that are left after 1st round picks and then the ramp bots that can both elevate robots for the bonus points and play effective defense.

Good luck to all teams!


edit//

Autonomous doesn't seem to be as important as it was last year. Spotting/tracking to place the keeper(13'' diameter opening) over the spider foot(10'' diameter) is going to be very tough. I don't see too many teams being able to consistently do that, but i do imagine a lot of teams speeding across the field in hopes of hitting an opponent looking to complete the objective of autonomous.

Probably not, but we're not sure. Those who put serious thought into it suggested inflatable ramps, but I think someone said that wasn't allowed. It's probably infeasible, but it'd be hilarious -and moderately effective- if it's allowed. This was partly in response to our programmers' gripes about the camera code. It's our second year, and we went all low-goal last year due to newbie programmers.
