Module 7: Drivetrains
The drivetrain decides whether your robot can get to the scoring position in time and hold it against defense. This module covers the common archetypes and the math that turns a motor choice into a real speed and pushing force.

What This Unit Covers
Compare tank, mecanum, and swerve drivetrains by capability, complexity, and failure mode.
Select wheels and understand how the coefficient of friction limits pushing force.
Compute free speed and pushing force for a proposed drivetrain and check it against the motor current limit.
Mount odometry pods so the localization the programmers rely on actually works.
