Image Discuss: 121 Teaser 1
 

Hrmm.. Question...

how do you guys deal with the fact that the Chippy is alot more powerfull than the Bosch motors, and.. im im not mistaken runs slightly faster than the Bosch?

~Pyro

Our driver is trained to hold the joysticks at different angles. j/k what we really do is gear ratios.....

The drill motors are actually the ones that are more powerful, about %50 and they also spin at a speed almost 4 times greater than the Chips. I understand now to match the speeds but how in fact do you adjust for the difference in power? Its like driving one side with 2 Chips and the other with 3.

that was last year. the drill motors are a lot more powerful last year

hmmm, you obviously never saw the drive train on Team 121's bot last year - it had the same setup, and worked very well. I also know that it was quite fast enough to give us (team 571) quite a headace when we tried to push them out of the way.

the left and right side , i believe, are run at different gear ratios in order to achieve the same speed. (true, one side is probably a little more powerful than the other, but i don't think that that affected anything much.

if you do it right like we have everything is same speed and power throughout.

Is that an illegal battery in there though?

I don't see how it would be. The battery can be in any orientation

But it doesn't look like the one in the kit!!!

We have multiple batteries that are not Exide, and use them for testing. To tell you the truth, I don't think there is a rule that you are required to have an Exide Battery.

wow...im really interested in your grearing system, i can't come up with numbers to make those run at the same speed and still have the same tourque....u can bet i'll be visiting your pit alot....good luck

well, the only way that i can think of for the power matching is in code. By limiting how much power goes to a particular motor...

It doesn't make sense to have 2 totally different types of motors to put out the exact same thing mechanically w/ or w/o gear ratios....

ok you wanna know what really powers our wheels. WE put these guys in little metal boxes and let them turn the wheels. THis is an artist rendition of what we do. We also feed the gerbils the same food. so power is equal. To make the bot turn one way, we use brakes on the gerbil wheel to stop power.

thats what the rules say

Just don't put them in the microwave and cook them. We talked about this in chemistry today, and the blow up.
