For NJ and NYC regional it was a 36:1 on the main belt, and 25:1 on the top roller.

In Atlanta we changed it to 25:1 on the main belt and 16:1 on the top roller.

Did you guys ever have problems with the hopper having a flat bottom, instead of having a sloped bottom to the front where the roller is?

[jblay]

well the base of the hopper comes up to a slant with the use of what i believe is a window motor. you may have seen this on 103's modification to a power dumper which was a concept they took from 2753.

Team 11 was one teams to lift their hopper up and dump (using a pneumatic piston). 2753 does the same thing but has rollers in the front aka making it a power dumper. But as pointed out earlier, overdrive uses a window motor.

I was the field supervisor for the Archimedes Division. The only problem I had with your robot is that every time that you competed I had to have two field reset people swifter the playing field to remove the worn conveyor belt material. Congratulations to your team on a wonderful championship. I expect to see great things from your team in the coming years. See you next year at the championship.

Haha, yes we did notice that.

We replaced the belt on Thursday with a new one and for some reason the new one shredder like paper. The older ones held up much better, so I am not sure what happened.

Anyway, sorry about that!

[Coach Tom]

If I remember correctly - Tyler - we changed suppliers of the "shelf-liner" material: Contact versus Kittrich. Also, we used Gel Contact Cement originally -- made by DAP. Our new belt used 4 minute spray contact cement from 3M. The sheddling of the belt did not happen in either NJ or NYC.

Lesson learned: do not change suppliers without adequate testing.
