Power Intro
Motors, shafts, bearings, gears, belts, and chains — the parts that turn motor spin into robot motion. This stage is about modeling them.
01
Beyond Structure
A frame doesn't move — power transmissions make it go.
- Motors make rotation; the rest shapes it into useful motion.
- Power transmission = motors, bearings, shafts, gears, belts, chains.
- This stage is about MODELING these, not yet selecting them.

What You'll Build
Standalone gearboxes, step by step.
- Learn each component: motors, shafts, gears, belts, chains.
- Model three gearboxes of increasing complexity.
- Ratio math and motor selection come in Stage 2.
Key idea
Motors spin fast and weak. Transmissions trade speed for the torque you actually need.
Everything here is that trade.
Recap
