Motor control — your first moving robot
From PWM duty to wheel velocity, why open-loop control is fine and when it isn't, and the L293D's hidden voltage drop.
This lesson is in production. The arc below outlines what it will cover. Arc Wiring the two DC motors as a diff-drive; mapping PWM duty to ground speed (it's not linear); reading the wheel encoders included in extended kits; a simple bang-bang controller; a P controller; when you actually need PID.
