Unless you're building a sitting duckbot, you'll need some motors. 🦆🏍️ Motors make your bot move!
Each bot can have 2-3 motors. With two, you'll have a bot that can be steered around and crashed into other bots like a demolition derby! If you want to include motorized tools like spinners to make your bot an even more powerful recycling machine, you'll need a third motor.
