We went to a Mailboxes Etc to weigh ED

The fact that some of you designed machines in which you were able to cut 30 pnds worth of holes out of really scares me. We drilled all the holes we could afford and still only lost about 5 pds. Are you people making your robots out of large flat sheets of 1" thick steel or something?????

We cut 30, but who ever said we did it with holes??

We ended up cutting out the whole pneumatics system...

Plus, PVC is heavy, so, put holes in it and where you can, replace it with something like aluminum angle....

Use a smaller chain....

instead of pvc you we of looked into thin wall alunimum conduent ....its both light wieght and strong at the same time ..it cut out 3 pounds off of are overall weight ...:D

I had thought about that, but it doesn't seem to good against balls...oh well.

I totaly agree in that aspect that the balls would slip ...we simply used a mess belt over them (the ones in small parts) to create friction ....it worked out great because the material was really tacky .....try it out on your pvc rollors. it might work great for ya !!

The more I think about it, the more i think that conduit would work for us. We don't actually make contact with the balls...we've probably taken out about the same amount of weight anyways. Thanks!

Umm...how do you pick them up if you don't touch them?
Telpathy is really cool, and prolly with in the rules....:D

Silly me,

We don't make contact with the ROLLERs...we are using a nice belt from McMaster the works wonders. I thik it takes less then three seconds from the time the ball hits the front roller to the time it hits the bottom of the basket. Lets hope it works the whole time...
