Let's Talk About The Bridge:

None of us could tell. Can't bring it down with your finger but put your foot on it and with a little pressure it came down. No exact measurements.

So I'll have to keep torque in mind. Really heavy weight is needed to tilt it from the middle area of the bridge.

On the video on Youtube they stated that if you place 2 batteries next to each other, 28 inches out, the bridge should stay level. Move it an additional 2 inches I believe, and it would tilt.

Use physics, convert and stuff, and there's your answer!

[Andrew Y.]

just put your battery on a linear slider and rack and pinion...

[G37] Final scores will be assessed 5 seconds after the Arena timer hits zero.

So, whatever you do to balance, make sure it stays in position after you lose power.

Does anyone have the wieght of a battery handy?

[plnyyanks]

IIRC, they're ~15 lbs

Edit: looking it up, they're 6.2 kilograms = 13.6686603 pounds (from the datasheet)

[Semi-teaser] Once you realize that getting FOUR full size robots on the bridge is quite possible without them overlapping, then the ways for easily getting three on and balanced start to look a lot easier to accomplish.

I would love to see if anyone builds "minibots". Yeah of you can get your robot down to 10x10 that would be intense but would probably not be very usefull so how about other weird sizes like 10x 20 I want to see something crazy like that designed for 3 bots on a bridge but still able to function during normal game play.

You can fit three normal sized robots on the bridge.

While smaller robots would make it easier, it's not impossible with "normal" sized robots.

You can fit four normal size robots on the bridge too, even the outer ones.

LOLOLOL

i want to see your math.

no really...

28*4=112 inches
+ bumpers=136 inches


ok so how do we get 136 inches onto 88 inches???

finishies lolrage realizes we have three robots per alliance.........

I didn't say that any match would be having an actual 4 bots on a bridge result.
I only said that four full size bots CAN be balanced on the outer bridges, and without overlapping each other
In order to imagine what I am saying you will have to start thinking more "outside the bridge"

Now that I consider it further, even five (5) full size bots can balance on the bridge

I now believe that even without trolling or overlapping, as many as eight (8) 27" x 37" robots could balance on the bridge.

I don't believe more than 3 could stay on as the bridge changes from tipped to balanced due to the angular momentum.

Thus, theoretical maximums are not valid compared to the real world physics of making it happen.

In fact, I believe we will see a number of rolled robots as in the elims as they try for 3 robot balances. Build your robot robustly
