One of our teams has an idea for a device that could use a large collection basket. Would it be acceptable to use some sheet goods (aluminum plate, plywood, or Lexan) to build part of the structure? How about only in a limited way, like a 2x2 foot piece of material, or only used for non-moving structures? Or, is this competition limited to Vex components? What if the device moved something from one place to the other, and the destination device was a bag or box not connected to the robot?
In case this is too vague, imagine that the local county fair has just closed and this device was a sort of super-Rumba designed to pick up trash. Something like that.
One excellent material for this type of thing is pegboard.
It has lots of advantages:
*]Has a VEX-friendly 1" grid of holes
*]Easy to cut; no splinters or sharp edges
*]Fairly light for its size & toughness
*]Very low cost
