Re: How much does your robot weigh?
 

Our robot weighs 120.0 lbs. That's my story, and I'm sticking to it.

Re: How much does your robot weigh?
 

I remember one year our robot weighed 120.1 lbs. We were allowed to play because the scale was accurate to plus or minus .1 lbs.

With a taste of irony, our robot weighs 103 lbs. Honest to goodness truth. haha

Re: How much does your robot weigh?
 

As of last night our robot weighs 113.4 pounds, it still needs some wiring done though and a couple pieces of lexan put on, so its gonna be close.

Re: How much does your robot weigh?
 

Our weighs about 105 with all the necessaries on it. I guess we'll be able to put on 15 pounds of cool decorations on it this year :cool:

If the words "I can currently lift our robot with my pinkie finger" mean anything to you, Try to imagine our robot's weight. Still a work in progress, though... :D

Re: How much does your robot weigh?
 

For all of the teams at a weight of like 110-120 (like ours) I just imagine them at last min, saying "Oh no we never put the bridge mechanism on...

Luckly ours is sort of on. And on a side note, do you think the inspectors would declare a Van Door motor with just a pair of vise grips attached to it, safe? That was the first idea that popped into my mind when making that mechanism lol.

Re: How much does your robot weigh?
 

we're looking at 111 as of about an hour ago, looks like it will top out at 115-120

Re: How much does your robot weigh?
 

Is that 20-30 lbs over or under? Because we designed an overweight robot in CAD, and then gave up on trying to adjust the design and said, we'll just build it and then swiss cheese it. But it Autodesk overestimates by 20 pounds, then we have a hundred-ten pound robot.

Re: How much does your robot weigh?
 

we weighed our robot today and the drive with all the electronics and lexan we are at 51 lbs. we still have around 50 lbs. left to add

Re: How much does your robot weigh?
 

Lucky enough to get a peak at awesome?

Re: How much does your robot weigh?
 

Sounds more like serendipity than irony ;)

Maybe we should build a 95lb robot one year... :D

Re: How much does your robot weigh?
 

How are you guys weighing your robots, we were thinking of using a hanging scale because last year the force platforms from the physics labs were off by quite a bit

Re: How much does your robot weigh?
 

To get a "close enough" weight of the robot, use a simple bathroom scale. Set one end of the robot on the scale, the other on a block to keep the robot level - that'll give you "half" of your weight. spin the robot around, and now you have the other "half".

I put half in quotes, because it's not really half - if your center of gravity isn't in the middle of the robot, you'll see one end weight more than the other. This can be a great way to help discover and fix CoG issues.

Re: How much does your robot weigh?
 

Put a piece of plywood down on the bathroom scale instead, then either zero out this weight or note how much the plywood weighs. Then you could put the entire robot on the plywood and weigh the entire robot.
