Re: MagLev C

I will start off saying that the third place robot arm team spent less then $350 total on the arm. Many pieces were scavenged from goodwill buys sush as the thrust bearings from an old drill. On top of that the biggest expense was having to purchase the transmitters and receivers this year be ause t...

Re: Elastic Launched Glider C

Hey guys, I’ve been reading through this thread and I’m not quite sure why everyone is suggesting all of these potential changes. Like what is the issue with the current rules? I agree that the event is based on luck a little more than it should be. However, I do not believe that the current compet...

Re: Elastic Launched Glider C

I agree with most of your points. The main difference between your suggestion and mine is whether to make target flight(s) separate. The only benefit about making it separate is so that teams are clearly aiming for best time vs target time. However, the top teams should be clearly aiming for one or...

Re: Elastic Launched Glider C

Also, if you make the bonus time somewhat random that's a lot of data collection. A big flight log. Comparable to a good teams GV log.

Re: Elastic Launched Glider C

I agree, counting all 5 flights does not allow enough room for mistakes. On the other hand having a data and repeatability event where success is based on 40% of your attempts doesn't seem right either. I think teams should need to be successful more than 50% of the time (to reduce winning by luck)...

Re: Elastic Launched Glider C

The exact time flight would be for bonus points. Not the contest. An elective like the raising of the ping pong ball. A completely separate flight from the scoring ones. A team that is held back because they don't have the a skilled mentor or ability to get the best wood to make the best glider coul...

Re: Elastic Launched Glider C

We are well aware of the flight log issues, unfortunately no one has come up with a reliable, robust and scaleable solution. In my opinion, the flight log is critical simply because it exists. I never said you weren't Now i may be taking what you said the wrong way but, multiple times i have had to...

Re: Helicopters B

Unfortunately, the only courts on campus there are completely off-limits to SO. Does that include the basketball courts on the second floor? the connected hallway with a smooth ceiling was a decent solution. For what it's worth, the team that won nationals last year launched in that hallway (althou...

Re: MagLev C

While I get the idea that you don't want to encourage solutions that require throwing more money at them to win, the rules for this year were designed in that exact way. Rare-earth magnet tracks were allowed with heavy vehicles being a significant advantage. Those two things together strongly encou...

Re: Helicopters B

I agree with ericb that anything that can be done to request an amenable environment for helicopters would be good - maybe a list of desirable / undesirable features (flat ceilings with few obstructions, at least 16' x 16' area per flight, ability to launch 2 non-interfering flights at the same tim...
