Control flywheel speed suggestion

Our team finished the regional competition last day of Jan. As the fist time joint Vex, time is too limit for us to build a robot and learnt the new programing system. And find out there are a lot things we should Leant from it. When we reviewed our project, and ask a question.

Why didn’t we use some equipment to measure the flywheel speed. Such some rotation meter. When in programing, there a function that we found during the competition something like “get batter power”. I think this function should be use to determine motor speed output value. Maybe there are some test needed.
