[Joe Johnson]

FIRST is very much a pick your poison sort of deal.

If you are going to let your robot get anywhere NEAR bevel gears (especially the bits associated with the drive system) then I recommend that you follow the example of The Dread Pirate Roberts when dealing with Iocane powder*: spend a "few years building up an immunity."

Bevel Gears are serious poison, at least as deadly as Iocane powder ;-)

Consider yourself warned.

*from the Princess Bride:

Dread Pirate Roberts: Good. Then pour the wine. <Westley pulls out a small
cylinder> Inhale this, but do not touch.

Vincini: I smell nothing.

Dread Pirate Roberts: What you do not smell is called Iocane powder. It is
odorless, tasteless, dissolves instantly in liquid, and is among the
more deadly poisons known to man.

Dread Pirate Roberts: You guessed wrong.

Vizzini: You only think I guessed wrong! That's what's so funny! I switched glasses when your back was turned! Ha ha! You fool! You fell victim to one of the classic blunders! The most famous is never get involved in a land war in Asia, but only slightly less well-known is this: never go in against a Sicilian when death is on the line!! Ha ha ha ha ha ha ha!! Ha ha ha ha ha ha ha!! Ha ha ha-- <Vizzini stops suddenly, and falls dead to the right>

Buttercup: And to think, all that time it was your cup that was poisoned.

Dread Pirate Roberts: They were both poisoned. I spent the last few years building up an immunity to iocane powder.
