2. What you will need

In addition to the Zumo chassis kit, you will require these items to construct a working robot:

Assembly tools

• Small Phillips screwdriver
• 3 mm Allen wrench (hex key)

Additional required components (not included with the kit)

• Two micro metal gearmotors (we recommend 100:1 or 50:1 gear ratio versions)
• Four AA batteries (we recommend rechargeable AA NiMH cells)
• Electronics to control the motors (e.g. the DRV8833 dual motor driver carrier)

Additional optional components (not included with the kit)

• One basic sumo blade for Zumo chassis

Please see the product description for the chassis kit for more information and recommendations about selecting these components.

You will also likely need a soldering iron to connect your motors and batteries to your electronics.
