Looks nice--the best one-point robot I've seen yet.

Good luck this season!

I hate to be "that guy" but doesn't that ramp violate <S03> based on update 6? It also may violate <R04>.

Re: pic: 213 Design

You can extend outside of the footprint! The only time that this cannot happen is for mechanism that throw or expel balls at a high rate. As long as the door does not move too fast there shouldn't be a problem as long as it is a low energy devise that does not exceed 3 m/s

Other than that...
How do you plan on getting to the goals? Is your robot powerful enough to push robots out of your way? Or is it fast enough to beat them there. From my experience Omni drive isn’t that fast or that powerful but highly maneuverable. I would also suggest adding side panels to the door to ensure that the balls don’t slide off the edge. Great conveyor design!

Re: pic: 213 Design

I'm pretty sure this robot follows the rules.

1) that fold down ramp isnt launching balls, just letting them roll into the corner goal, so it doesnt count as a launcher that has to stay in the foot print
2) as far as the wedge rule, so long as the ramp is mounted above 8.5inches (the top of the bumper zone) they are not breaking any rules. <R04> states that parts of the robot between 0 and 8.5 inches off the floor must be 10degrees from vertical. Other parts should be designed to avoid wedging, so as long as they dont go using it to push against other robots they will be fine.

Sanddrag: this picture shows their prototype drive, you can see the belts they use to drive the wheels.
http://www.chiefdelphi.com/forums/pi...&quiet=Verbose

To Team 213, my only suggestion (which you may have already thought of) is add something tall to the bottom of that unloading ramp, that stops your ramp from crossing through the opening of the corner goal, so you dont risk interefering with the scoring system. My old team had to do something very similar in 2004 to keep our ball collector from breaking the plane of the alliance station wall.

Re: pic: 213 Design

Are you going for the ramp, cause if you are, I would drive up your chute and score points for myself as well. lol

Horray for piggy-back bots.

Re: pic: 213 Design

I've read all of the rules and Q&A's pertaining to this issue, but there are conflicting opinions. ok, so what's the final word. Is this design legal or illegal?

*assuming there are no obvious violations and that the distance between all points of the "ramp" and the ground exceeds 8.5 inches.

Re: pic: 213 Design

The problem is based on answers like the this:
http://forums.usfirst.org/showthread.php?t=424

And this:
http://forums.usfirst.org/showthread.php?t=439

Many of us have argued whether or not a ramp is a shooter. It depends on how you define the interaction of gravity in the situation.

When you look at question like this:
http://forums.usfirst.org/showthread.php?t=327

It gets muddier because the ramp is delivering the final impulse on the ball in a ball ejection system.

While in another series of posts based on <R04> is sounds perfectly legal.

I know I'm going off a little off the point here but this was a "Devil's Advocate thing". I mentioned it so that team 213 would feel comfortable that they are within the rules and be ready to argue the situation with the proper Q&A in hand if necessary. With all the discussion on this board I think preparation for talking to the inspectors needs to be made for such a device.

Hopefully this Q&A is still in effect: http://forums.usfirst.org/showthread...hlight=gravity

It was written several weeks before Update 6 was released.

Although in our case it may turn out to be a moot point, as we may be too close to the weight limit to install a fold-down door.
