The spring force is converted to kinetic energy in the wheels, motors and entire minibot by the time Deployment starts (minibot is over the platform) so I think it is as legal as ramp deployments in general. Of course, I don't interpret the kinetic energy ramp deployments have before Deployment starts as incidental (like G19's blue box says) so interpret all of them as illegal. I interpret incidental kinetic energy as the wheels & motors free spinning, not kinetic energy of the entire minibot (most importantly the battery) moving.

Of course, my interpretation doesn't matter. The GDC does not perform design reviews, so it is de facto legal unless a head ref says it is illegal (then tower is disabled). As a spectator of events (live or webcast), I want ramps to be legal since they are a really cool, creative idea by teams like 56, 190, 233, 368, etc... and implemented/optimized by many great teams. Titanium's is the first swinging arm ramp (most are flop down or extend) I've seen, great job. Pink did the correct thing by asking the Q&A (right when regionals started) in a grey area . GDC probably should have provided some interpretation, even changing the blue box under G19 if necessary. The Q&A shouldn't review every design, just a few unique ones with grey areas in the rules like the ramps this year, 469's last year (pretty clearly legal), 190's 2008 bot (they still have a sense of humor about it), etc... so it is not left up to the head ref at their first event. Maybe they should just review all 190's bot's before ship since they always strive to create a unique, outside the box concept, robot ;)

OK, enough of that rant, it has been building for over a month. Since the spring thing was brought up I couldn't resist (I've had conversations like this before and mentioned it on webcast chat rooms but I have never seen a similar opinion expressed on CD). I don't want to hijack the thread. To debate legality of ramps back and forth is unproductive. I have my interpretation, everyone can have their own interpretation, no one is right or wrong because it is not clear. Since there haven't been any tower disablements (probably would have heard about it here) it is de facto legal. Since I will be watching Curie this week, I hope to see a quad ramp match with 1986, 368, 1678 and some other ramp bot (that we probably haven't seen yet) beacuse that would be awesome :cool: Curie might just be the "Minibot Division" between these all ramps and 2081's timing challenge (without ramps) in the pit.

I think the swinging arm would have worked, but we wanted to put positive pressure on the pole. To accomplish this we have joined the flop down crowd. Same pneumatic commands, but different pivot orientation.

Watching 368 in the Hawaii finals is what convinced us that the ramp was the only way to go. They had our full attention having a regional in such a unique time zone. We are looking forward to sharing an alliance with them at some point this weekend as well.

PS. I am hoping that the GDC reduces the 30lb with holding allowance for the next season. The ability to redesign and bring in 1/4th of the robot makes it too easy to reverse engineer other designs. 12 lbs (10%) is plenty, especially if the bumpers are not included.

Only if they exclude identical Spare Parts from the weight limit. The majority of ours is spares. Who cares how many spares you bring to the event?

We found this to be the case also, however I'm not sure the same holds true for rampbots. Having initial verticle velocity changes the whole equation in favor of larger diameters.

i cant exactly tell but it looks to me like you use springs to accelerate the minbot off of the launcher i know its in the horizontal but that has to translate in to movement up the poll that does not come from the battery

No spring or other assist, but I'm glad it appears that way!

Looks great! Nice work guys. Good luck to you and your team at Championship! :)

How awesome would that be? Looking forward to seeing everyone this evening and the rest of the weekend!
