I submitted this question to FIRST. Perhaps others have ideas on this.

Can a robot design mechanism intended to prevent their robot from being pushed off the ramp by extending wider than the distance between the ‘uprights’?

For instance, a team may drive up the middle of the ramp and then put out 4 foot outriggers on each side of their ramp. These outriggers would not clamp on to anything, they would just hang off the edges of the ramp. If a competiting robot tried to push the outrigger robot off the ramp the outriggers would interact with the poles of the goal, but they are not actually touching the goal otherwise.

I suppose that rule M7 makes this robot illegal. Others on our team disagree.

Is the type of mechanism legal? Please clarify.

I think that this qualifies as illegal… you’re making a system that is designed to react against those supports, even its only some of the time. it seems to me that the intent of this rule is to not let us do anything like that and have us swing like monkeys off that bar…

I think you’re right, Jon - since the robot would be designed to react against the upright, it would violate the rule.

Joe,

There’s been quite a bit of discussion about this topic. Based on everything I’ve see I think that this machine would be illegal, becasue it is reacting with the supports of the goal (update 1 Q3, GM23, M7). However I was thinking the other day about one of the machines from last year’s comp. that extended a PVC grid like structure to prevent teams from getting up on the puck. I think doing something like that to block the ramp would be perfectly legal provided it does not attach or react with the goal.

My Thoughts,
-Justin

I’d have to say that one is illegal. They don’t even want teams using C shaped alignment guides for lining up with the goal. And Dean also made a point at kickoff that teams can only intentionally touch the striped bar on top. Those outriggers of yours are obviously designed to touch the poles, even if they only do when another robot pushes you. That’s my 2 cents on the matter.

Does anyone else feel that the not touching the goal intentionally is going to create a lot of havoc on the field? Robots being tipped and such. That especially worries me since we don’t have time to fix the robot between competitions. A few falls could really kill it for good!

For the first time in four years our robot will not have a way to steady itself while scoring the game objects, only for hanging. It does make you think carefully about your scoring strategy.

I predict the floor next to the ramps will accumulate a lot of scrap robot pieces.

Joe, I would say this is illegal and that you would be disqualified, since the rules state that the only place where the robot can interact with the goal is the yellow and black striped bar.
