[OCCRA]: May we use a sanding belt for a conveyor?

[Clint Spevak]

One idea by our team is to use a sanding belt for a conveyor function on their robot. But an experienced member objected saying 'the Rules Committee will say we are damaging the playing balls, and that we can't use sandpaper.'

Is that true? I get it that a design which wears out the ball by sanding would not be good, but a sanding belt also could be used without significant risk of damaging any ball.

What guidance can the team have before inspection?

Answer:
Robots should NOT have designs that will damage the FIELD (including the carpet), GAME STRUCTURES or, GAME PIECES. Any robot found in violation will be required to have a re-inspection and be required to stop the damage condition or be disqualified in any match it re-occurs in.

Damage to game pieces may result from sharp edges, fasteners, and as a result of grip, compression or launching (striking with something). If damage occurs the team will need to be re-inspected and demonstrate that the condition was repaired.

As to the use of sandpaper (abrasive belt)..... I would think that the friction of the rough surface upon the ball would result in surface damage and lower the grip for other teams and as a result would not be allowed. It will be up to the team to demonstrate that no damage is a result of their mechanism.

Bottom line..... as long as no damage to the ball occurs it will be legal.

HINT: There are other products that will accomplish the result you want with NO damage to the ball.
