I would look at the documentation available for pre-existing robotics library code such as the WPI Library so you know what exists already. Also, gain some familarity with the sensors and what exists (quadrature encoders, potentiometer, limit switches etc.) If you have an idea on how to accomplish a task but don't know what tools you have then try to look it up. Other teams also made their source code open-source if you wish to learn from it.
