Robots that float

[MikeDubreuil]

Theoretically, you could lift up your two alliance partners while being supported in the air by pool tubes. That seems to be the only legal way to have all 3 robots off the carpet.

No longer legal per Team Update #1

Section 7.3.6, Rule <G56> -
“ROBOTS score bonus points at the end of the match if they are entirely in their HOME ZONE, not in contact with any element of the field (carpet, alliance station, goal, etc. - note that for the purposes of this rule, GAME PIECES are considered field elements) and the lowest point of the ROBOT is higher than 4 inches and/or 12 inches above the carpeted field surface.”

P.S.
Remember to drop any tube you are holding before climbing a friendly nearby ramp.

ok first thing about hovercrafts.... the skirt still countsas part of teh robot
so you wouldnt get any points for it.

AND after the 5 secend warning for the end time you cant stop a robot from leaving your home zone.

if <G09> holds the way it is now i can see my team going undefeated, even with the bonus points

Im still thinking that you can throw a zipline into the rafters and hang from the celing

Practically speaking, I don't think a hovercraft is feasible.

amen...

the thing is the robot doesn't need to float the whole time. It could only float at the end when it needs to if its possible.

Your robot cuts off at the end of the match. This would be impossibel to keep it off the ground without any power..( well...if you could use your mind to keep it up i guess you could use brain power )

That is why brain power is wonderful!

1 there is alot of contact on a first field, the odds of the skirt getting torn of folded up so it forms a poor seal with the floor are pretty high.

Also a hover bot would just be pushed around the field, it would be like an air hockey puck.

For any one who was looking at this strategy to score points at the end of the match, keep in mind that power is shut off and the robot wont be able to keep hovering.

These are the same people that say having a monkey for a pet is a bad idea.
I think in the future, both ideas will have their place in the world of FIRST.

Just to mix it up a little bit.

Can you potentially build a robot so small, so light, with just the basic components that it weights about 10-20 lbs, and it attach itself to another robot such that it remain off the ground for the entire match?

Think super small version of the 2004 Bionic Poof robot. Small arm that latch onto another robot and winch itself up.

Yeah....

it would be surprising to see a hover-bot, but i don't see it getting past regionals. it would be easy to push around, and/or acually accidentally tipped over. and for whoever said lines to the ceiling, if that's not actually in the rules, if your rope got caught up there, there isn't going to be a great way to get it down. so you may get penalized.

As an add-on/side note to this idea, last year 1006 made a hovercraft for our robot cart. For that purpose the concept works wonderfully (Apart from when the battery on the leaf blower dies half way to the field...). It was quite simple to make, didn't cost much, and made a great conversation piece at regionals. Hovercrafts are awesome.

The force needed to lift a robot should be simple to calculate, so I figure I'll try it out. Someone correct me if I make a mistake. We're going to start with a 120 pound robot. Now, assuming you choose to leave a bit of extra space, we'll go with a 26x36 robot base. the area is 936 square inches. So assuming you can have a fan put out a constant pressure output of 2 psi (shouldn't be too hard to do with CIM's...), and also assuming you can cover the entire base with the same pressure, my math tells me the hovercraft would be able to hold 1872 pounds. I may be way off here, but at least I'm trying. Lets assume that only 50% of the bottom will be lifted. This could happen by spreading out two lifting fan setups. The simple 2 psi system would be able to lift 936 pounds before going back down to the ground. Assuming that you are never pushed, this could actually be a viable system to drive a robot. You would be very manueverable, if you were careful and scientific in your maneuvering fan setup... Or you could steer it with another method, like a crab module or two in the center.

Again, please correct me if the math is off....
