Answered: College sensor with arduino for processing

My Teams interpretation of this rule was that we could use an arduino to interface sensors (that only have I2C) and do the processing, then report values back the Vex Microcontroller to do further calculations and set motor speeds.
However a recent forum post suggested this would be illegal as there interpretation was that ALL sensors had to plug into the Vex Microcontroller first.

Are we allowed to plug our I2C sensors into the arduino and not the Vex Microcontroller?

Thanks Scott.
