What is an MCC?
An MCC (Minimum Competitive Concept) is a robot designed for FRC games that uses the fewest resources possible (money, time, equipment, knowledge, etc) to play the game at a level where the robot is valuable on any playoff alliance. When tuned, the MCC is often an alliance a captain due to its robust and consistent nature. These robots often have a lower potential score ceiling than some of the super star robots but are key contributors to their alliances.
Use 1:1 Scale paper print outs when you don’t have CNC tools
You can still take advantage of CAD programs (Onshape, Solidworks, Fusion 360, etc) even if you don’t have
CNC machines. FRC#558 details this method in a youtube video. This is useful for getting chain or belt
spacing correct or finding the right place to put a pivot for your pneumatic cylinder.
This is a great tip. It allows you to make a lot of parts you wouldn’t think would be possible with only a drill and band saw. While it’s not perfect for everything it can normally be good enough. 5254 has used this method extensively for both prototypes and parts on the final robot.
I would like to suggest adding a short paragraph in the “Shafts” section on how to use them as dead axles to transfer very large torques i.e. pivots for long and heavy arms.
A link to a basic guide to workholding would probably help many teams improve the quality of their construction significantly. Unfortunately, all of the ones I could find are oriented towards large machine tools such as milling machines, but the basic concepts are the same and many of the techniques can be emulated using C-clamps.
