Optimization and Analysis of Drivetrain Movement
_Gear ratio selection is typically based upon theoretical top speeds or pushing power, but oftentimes, this isn’t the criterion, and is a poor model for actual events. Sprint distance can play a much bigger factor for agile defense.
In this, we’ll take a look at how to optimize based on reaching a certain point first, rather than being as “fast” as possible._
In the High Level Overview, basic facts about motor curves and limitations of our models are brushed over.
In the maple sheet, I use differential equations to model the velocity and distance travelled of a typical FRC robot as a function of time and gear ratio. This will then allow me to target a specific “sprint” distance, solve for required time, and find the gear ratio which reaches this distance in minimal time.
