I think if you set the weight budget about 10 lbs under the max weight allowed, and you keep track of it during build, you can probably get the robot done within wieght. Also if you start with a heavy drive base, it's easier to shave weight off it at the end if needed, than if you start with it as light as possible.

I think the main advantage to reducing weight on the robot is so that if you go over (as we along with many other teams did) then its just another piece that can be lightened.
I understand the worry that you would add the weight higher on the robot but I believe that the trade off of guaranteeing lighter weight over messing up where you put weight is worth it.

Also I find it easier to simply not put weight high rather than trying to monitor your weight all along with a heavy gearbox.

Re: The best multi-speed transmission

For the past two years Team #39 has tried to use the transmissions that come with the KOP. We felt it would be easier to help rookie teams if we had to overcome the same problems they had. After the Banebot problems this year we do not want to use them next year. My question is, do you think the KOP will have the Banebot transmissions next year? If they do, I think we will return to the AM trany.

After experiencing the problems they had with them this year, will they be the same exact banebots 56mm trannys?? my guess is no...

FIRST learns from their mistakes, and I think after seeing the huge struggle teams had with these this year, they WILL correct it.

As far as trannys go....254/968...the thing is just unbelievable. If you haven't seen it yet, hop around delphi and check it out:

Serious props to the guys over on the left coast for designing this thing. My entire team was drooling over it (and the rest of your guys robot ;) ). Travis, thanks for explaining the hard anodize process to me, its definitely something we'll be looking in to.
