Re: Gus 228's 1.3 second Minibot
I am not convinced that this is legal.
I understand that your minibot provides all the energy for vertical movement - no energy comes from the hostbot. However, there is more to Rule <G19> than just where the energy comes from. It also requires all such energy to be provided "after the start of DEPLOYMENT". Section 1.6 of the game manual defines the start of DEPLOYMENT as the moment at which the minibot first crosses the vertical projection of the tower base (not when the clock reaches 10 seconds, and not when you press the "deploy" button on the control panel). The "blue box" advisory on <G19> states that "Energy for vertical movement may not be stored in the MINIBOT before DEPLOYMENT". It provides an exception for "incidental kinetic energy stored in the motors or wheels, but NOT, for example, in a flywheel". Nearly two weeks ago, I posted a question on Q&A asking whether the self-generated horizontal kinetic energy in a minibot prior "DEPLOYMENT" would be considered "incidental" (therefore legal) or "stored" (therefore illegal). Clearly, the minibot benefits from it. We were considering this approach and were trying to get clarity before the Championship. My question was not answered. There is another Q&A topic regarding this issue. The response has been interpreted as an approval of ramp-style deployment, but the question is conditioned on "after deploying the minibot" and the answer also includes the phrase "after the start of DEPLOYMENT". Perhaps we understand deployment differently. |

Re: Gus 228's 1.3 second Minibot
Hilary has been telling me how hard you guys have been working to try to get the fast mini-bot, and it looks like it's paid off.
It looks fantastic and great job on perfecting a design like that! Best of luck in St. Louis, we'll be routing for you back here! Last edited by dag0620 : 21-04-2011 at 22:01. |

Re: Gus 228's 1.3 second Minibot
Just saying Team 2751's mini goes up in approximately 1 second not counting about a 1/3 second deployment. We also deploy automatically at 10 seconds. Look us up on Youtube our username is frc2751. See you all in St. Louis.

Oh come on. This thread is about 228's deployment, hype your own elsewhere.

I hope to not be offensive but I want to point out a couple things I see. First off I do not see how you can say that your minibot has no stored energy other than the battery. If we take the state of you minibot a split second before deployment starts(crossing the vertical projection of the tower) you cannot say that your minibot does not have kinetic energy inside it. Especially since the minibot is moving! This is the problem I am having. I have no problem with the ramps as it was something my team was also planning on doing. However we were a bit nervous on the ruling and did not want to get an illegal ruling especially at champs Given that, my interpretation is that a minibot that starts deployment from rest and goes up a ramp should be deemed legal (see 1678's ramp+minibot video) and is an elegant solution to the problem. whereas a minibot that starts accelerating before the start of deployment and has kinetic energy stored in it to go up a ramp should be deemed illegal. Finally the incidental motor+ wheel kinetic energy is just that, motor and wheel. This means that that kinetic energy is not contributing to the kinetic energy of the system. |

That combined with the number of high profile teams that have competed with this system so far means it's not going to be made illegal at champs. |

Re: Gus 228's 1.3 second Minibot
only part of the minibot has to cross the perimeter before it rockets off, there are plenty of different ways to do this. our motors to not turn on until after the start of the defined "deployment"

Boy I sure hope that's not the criteria for determining legality.

Re: Gus 228's 1.3 second Minibot
I've heard many of teams still question the legality of this design, itd be nice for the GDC to just flatout say yes or no to ramp designs. Also I cannot say this is the best design. Yes 233 and 1114 have perfected it, but other teams seem to have issues (may not be exactly from the ramp) with this design. I'll take my normal bungie deployment that i know works and fast minibot. I like the design, but I see issues..

Re: Gus 228's 1.3 second Minibot
My argument in that statement was that many teams that are well known have competed with this design, and were not ruled illegal. The GDC in the past has ruled things illegal after teams have used them at events, and this has not happened this year.

Re: Gus 228's 1.3 second Minibot
I see it another way... Consistency is pretty important. If we're told the line is here, I'd rather they not change it without notice!
