Daniel,
We decided to use a sanding belt on our robot, however we coated it with a very thin layer of clear silicone 2 caulking. This effectively made it into a light-weight rubber belt. It grips better than the sand paper and will solve your problem. It will not add much weight and will dry in about 12 hours. You don't need to pass inspection to practice so you can wait for it to dry all day and then go to inspection and then use it the next day. You can use a large spackling knife to apply it. Apply it just thick enough to fill in the pores. We also used this on a custom flywheel that we machined. Very light and very effective. It does not tear the ball like a tire tread does and we exceeded 12 m/s until we geared the wheel differently. Hope this helps.

By pure accident, I was re-reading the rules, and found a new document for Robot Inspectors: http://www2.usfirst.org/2006comp/oth...tion-rev_C.pdf
On page 6, it says that sandpaper is specifically not allowed. However, I've reread the normal robot rules (that teams are expected to read) and found no specific mention that sandpaper is not allowed. The problem is is that our coveyor belt is made of sandpaper. We've tested it, and it does not more than lightly scratch the surface of the balls-far from anything we ever considered as "damage." Now it's the night before the regional, and i was wondering if anybody had any interpretations of this rule or any suggestions for us? Do we have to replace the belt? |
