Is it possible to add an arduino board to the bot?
 

Im not sure if this is allowed or not (i feel like there is a rule limiting you to 1 cpu)

It would be considered a custom circuit and need to conform to the appropriate rules especially R54.

Hmm, I would be using it to control some PID algorithm for balancing and moving pistons so I don't know where that rule falls.

It must talk to the cRio to control said pistons. The Arduino may not directly control anything that moves, essentially.

According to the blue box under R55:

Thus, as long as the Arduino gives its data to the cRIO, it should be legal to use it to process information.

You could have it do all the calculations and possibly output data to the digital sidecar. Haven't fully thought through this though. Possibly I2C? Can the digital sidecar do SPI?

The Arduino has a slave I2C library.
