SPINNER WEAPON STARTER PACKAGE
So you've built your bot, or at least have what you need for the drive and control, but now you're adding a weapon- a spinner to be exact. You've seen the destruction that some of those weapons can do and want to try it out for yourself.

With the items here, you'll be well on your way to smashing up the competition!

Just add the spinner itself (bar, disc, saw, whatever), along with it's support system and bearings, and some sort of geardown system between the motor and the weapon (gears, pulleys with belts, or chain with sprockets). You'll also want a good high-discharge battery source with some high current wires.
