TOPHEAVY!!!!!
 

just woundering who is top heavy and how isnt, if your are what are you doin to make it stay up, and can it get itself back up. i will tell you a little about our robot to start
We are SLIGHLTY top heavy, we made a box for our battery, air pump, and some other smaller things that we will actually have a piston to push it out the back to give us counterweight, and we also have stablizers coming off the front. so we're good. :D

what about your team.

oops must of accidently put it in the wrong place..... :confused:

Re: Is your robot top heavy?
 

With two 14 lb transmissions only an inch off the ground I'd say no. :D

Re: Is your robot top heavy?
 

good point there...where useing...dare i say BALL DRIVE!!!1 :yikes: hehehehe

all thou i shouldnt have sayed that

Re: Is your robot top heavy?
 

our robot is good looks like were going to be 10lbs under it goooooooooood
haha :D :D :D

Re: Is your robot top heavy?
 

Our robot is very stable...so far....at least it seems so

Re: Is your robot top heavy?
 

we have trouble just trying to tip our robot over. we have to drive it 7-10 feet per second and force it to a complete stop in about 1 second for the rear wheels to raise maybe 3 or 4 inches off the ground and then returning back.

Re: Is your robot top heavy?
 

^I was wondering what direction you tried to tip your robot. We decided early on that the problem would be getting hit from the side while you have a tetra raised or if you are topheavy. just my 2 cents make sure you are stable to the sides :-) good luck!

Re: Is your robot top heavy?
 

if you were referring to our robot, we drove the robot full speed forward. regarding top heaviness, i've lifted the entire lifting mechanism (shaft connecting to chassis, gears, arm and gripper), and it can't weigh more than 25 pounds. well for the sides, never looked at that. i doubt that tipping over will be a problem for our robot, but only robots on the opposing alliances! >=D

Re: Is your robot top heavy?
 

Suprising even with our arm extended completely up, our robot remains stable. This is mostly due to our battery and transmissions being about 3 inches off the ground.

Re: Is your robot top heavy?
 

Our Chasis is only 1/2 inch off the ground, mostly of the heavy stuff: battery, compressor, storage tanks, transmission e.t.c is on the chassis. So our robot is very stable.

Re: Is your robot top heavy?
 

Yesterday we took our robot over to the drama room (home to high ceilings, dark walls, and, most importantly, CARPET!) to give it a spin.

With all newbie drivers (well, some had driven it earlier, but not like this) and a tetra on the end, we were capping like nobody's business.

And not once did it tip. In fact, the only incapacitating moment was when a low-hanging screw got hooked on the wood platform about an inch off the ground in the room.

Re: Is your robot top heavy?
 

we have tried raising the tetra to full height (high enough to stack the middle goal) and were unsucessful tipping the robot even when we drove it full forward and then slammed it into full reverse.... anyways, if it falls down, we aren't screwed anyway ;)

Re: TOPHEAVY!!!!!
 

I want to see your active stablilization! That sounds neat. :)

We are stable and underweight. Therefore we abandoned our outrigger plans. Our team planned for mounting battery and and compressor to help lower and center our center of gravity.

Re: Is your robot top heavy?
 

"Yes, our robot is top heavy, please come tip us over"

Is that the type of responses you expected?

Re: Is your robot top heavy?
 

Yes, our robot is top heavy, please come tip us over! Pleeeeeeease! :eek:

Re: Is your robot top heavy?
 

We suffer from slight topheavyness. Actually its pretty bad. Since we have a rotating turret... Slam it forward with two tetras on the hook and none on the base we come within 2 inches of going past our CG. Luckily with some 8 1/2 lb tetras on our base for most of the match, we should be okay.

Re: Is your robot top heavy?
 

Ours is only top heavy once the tetra is being lifted past 2.5m or so. At that point it only risks tipping over if our arm's operator swings it all the way back randomly O_O (which he would know well enough NOT to do).

Re: Is your robot top heavy?
 

With our arm completely extended with a vision tetra on the end I was doing donuts and trying my hardest to tip her over didn't happen.

Re: Is your robot top heavy?
 

Our robot is definately not top heavy. After the start of the match we crawl down the wall so we are only 28" high, 38" wide, and 60" long. even with the arm on it fully extend we stay solid on the ground. From previous years I learned about being top heavy.
