Go to Post I would be kinda creeped out if I was one of the "famous" FIRST people. Why? Because no one is any different than anyone else in my eyes. Granted, some people stand out more, but that is because the other people might not have gotten a chance yet to shine. - Melissa Nute [more]

: hi,
: My team and i was wondering if it was legal to design a robot that could take off and land like a helicopter, doing away with a drive system and not having to worry about the ramp at all. With this design, we can do a number of things easily...like pick up the strecher and fly it accros to the other side, or pick up the ball and put it on top of the goal or put the goal on the bridge to balance. I think this would be a great idea if it is allowed in the rules.

As well as the weight issue, there are many strategical disadvantages to a helicopter. First, any system that allows you to pick up balls and put them in the hopper will be very slow. Also The fine contol needed unless you can somehow scoop the balls will be VERY difficult. I have worked with remote helicopters before and they are very difficult to stop quickly or accurately. From over 24 feet away, you also have a problem of seein gexacly what is going on.
Picking up an 80 lbs. hopper is out of the question, and the large balsl would also be difficult. If you could pull off the eingineering to make a working helicopter robot, you would be able to design a much better robot by puttign you energies in other places.
