If you can afford to, stock up on standardized motion parts for making manipulators (arms, shooters, intakes). This means some hex or keyed shafts, and then gearboxes, bearings, hubs, wheels, and sprockets/pulleys that match it. You'll also need chain or belts.

From my time in FRC I think that teams that are inexperienced or lack mentor support seem to struggle the most with creating motion consistently. Most teams can figure out how to bolt some wood or metal together to create a super structure, even if it is rickety and held together with four different bolt sizes. Getting power from a motor to a game object is a different story, and you can't really zip tie shafts together when you find out you don't have any hubs or sprockets to mount to your motors.

I might be a little biased with my response today as I learned earlier that we don't have a chain breaker (one of the most common FRC tools) since our veteran team has not had chain on a robot since 2012, and it walked off sometime in the last 4 years.
