2.3 Drivetrain subsystem

Motor → V-belt → reducer → gear train → cam bearings → interface with transmission yoke. Mounts on drivetrain mount plate (frame).

Reminders: Provide Sumitomo Cyclo 6000 reducer specs. Provide more specs for WEG 22 1450 rpm motor. Additional drivetrain details to be added later.
