Hypothetically, if one wanted to use a spring-loaded fulcrum to launch their minibot up the tower, would that be legal? Would the minibot then be considered a projectile? Does the minibot have to use a motor?
Would this be considered a safety hazard?
Could this (or a variation of this concept) be legal?
::rtm::
<G20> ROBOTS/HOSTBOTS may not contact their own TOWERS above the DEPLOYMENT LINE. Violation: PENALTY for contact. TOWER is disabled if MINIBOT is DEPLOYED above the DEPLOYMENT LINE.
In my interpretation that would amount to deploying it above the Deployment line.
Please start by reading the rules.::rtm::
Safety: I’d personally regard this as a major safety violation. You’re throwing something of significant mass (15 lbs) up something like 10 feet vertically. If you miss and hit a ref, you can expect not to ever be allowed to use it again–assuming you pass inspection in the first place.
Legality: There is a deployment line on the poles. Contact above that by the robots is prohibited (minibots excepted, but they must be free of the robot–See Game Section 3.1.5 for details). Also <G20> applies.
I don’t see any rule that the minibot must use a motor–Game Section 4.3.14–but you’ll need to latch on somehow.
But if the minibot is essentially a projectile, then it wouldn’t need to be very heavy, maybe a few pounds max, and if it is latched on well enough, it should be quite safe.
But another thing the think about is whether there is a maximum force which you can hit the target, just in case the target gets broken by the minibot.
Regarding the comment about it weighing 15 pounds, there is no requirement that it weighs that much. If it was a project alone, it need not weigh very much at all.
I’ve read the rules, I just was wondering if there was anything further on the subject, and what other’s interpretations where.
It says contact with the minibot above the deployment line is not allowed.
Given that there is an eighteen inch space for this spring fulcrum to launch the minibot, there may even be space for sufficient acceleration of this bot.
Further ideas?
If it misses, it’s very dangerous. Then you throw in the deployment line rules.
Poof balls and soccer balls are meant to deform when they hit something or something hits them. If you threw a metal ball of similar weight, it would hurt more. And there is very little padding allowed by the Minibot rules. Imagine a latching device-say 1/2 lb–launched upwards to the target. That’s some significant force (must be dealt with on the robot), plus if you miss, you not only have velocity but all the KE you have from the altitude. If you miss and there’s a ref or robot right there, they’ll probably move out of the way to avoid getting hit–if they can. Now your minibot hits the floor. It better be sturdy, and under <G46> and <G42>, you’re liable to penalty as well.
If you miss, and I’m the head ref at the event, I’m probably going to call you on safety, too.
The risk ain’t worth it.
Deploying above the deployment line is not allowed.
If the minibot crosses that projection above the line, no good. If I’m reading the definition right, the launching and the latching would both be parts of deployment, so if you latch higher than the line, no good.
Also see the safety notes I’ve suggested.
can we just shoot the mini robot up to the top of the pole or does it have to stay at the top for an amount of time? **
Those of us that downloaded the encrypted manual haven’t been able to find an answer either. Q&A opens on Wednesday, by tradition.
However, I would advise against shooting one, due to reasons I’ve already discussed.

how tall is the pole?

yes thats what i wanted to know and thanx!!*
From Section 2, about 122 inches up. And, before you ask, depending exactly where you hit it, you’ll need about 2-4 N to trip it.
BTW, as Gary pointed out, there is no rule saying that the minibot must stay up. However, the first Update may change that, and if not, the Q&A will probably be asked. In other words, it may or may not stay that way.
We are very interested in this too. Obviously the minibot would have to be very light to be thrown, and since it appears that the minibot (might) not have to stay at the top of the pole, and that the switch does not take much force to activate, I don’t see why it would pose a safety violation…although whether it is legal or not is another question…
i have a couple of other questions, my team n i dont have the rules yet due to the rest of the world try’n to get the rules all @ the same timeP:
*can we use external power for the minibot?
*what is the pole made out of?
*can you take only one minibot into the arena?
*is there a floor line that leads to the pole so we can line up a minibot?
*can we control the minibot via remote once released from the large robot?
if u can answer these questions for me that would b AWSOME!!!
If the minibot is connected to the tower the same way the ones at the kickoff were, but were deployed with the spring system, it would not detach from the tower, therefore eliminating all safety issues. If it is really light, it will not break the top.
We were debating this, and we raised this question; however, we came to the conclusion that if anything were left at the bottom at all, it would definitely exceed the 12" dimensions on the minibot. Good luck!
EDIT: Just found this in the rules:
<R101> If a MINIBOT is rejected by inspectors due to a safety issue or concern related to the team’s method of storing energy, the concerned items must be disabled or removed from the MINIBOT before it can compete in a MATCH. The team bears the burden of proof that such a rejection is not valid. Teams should be prepared to provide justifiable test data or calculations during inspection to support their design.
Storing energy in the form of pneumatic pressure or a spring to launch it is probably considered, as someone said before, a safety violation
This is why the encrypted manual is released. It’s so that you download it ahead of time and avoid the rush. Guess a lot of people missed that memo this year.
The answers can be found in Game Section 4, Game Section 2, unknown, Game Section 2, and Game Section 3.
In order, No attachment, but there is a battery allowed, Steel, unknown, Yes, Not if you want to get points, and there is a risk of hurting your entire alliance (Short version: If you don’t get to the top, the first pole on your alliance is not counted)
I think the biggest problem with spring loaded minibots are that there are no springs in the FTC KOP.
Sorry for having so many posts, but I just found a rule that PROHIBITS ANY LAUNCHING MECHANISM WITH STORED ENERGY INCLUDING PNEUMATICS, SPRINGS, AND OTHERS NOT MENTIONED!!!
