Prototyping and Engineering Tips from Robogears
Deck Placement Strategy: Always place your heaviest component—the battery pack—on the lower deck to keep the center of gravity low. This prevents the robot from tipping over during sudden starts or stops.
Universal Wheel Maintenance: If the robot isn't turning smoothly, check the caster wheels for dust or hair. A small drop of silicone lubricant can keep the steel balls spinning freely.
Wiring Cleanliness: Use the space between the decks to route your motor wires. This keeps the top deck clear for OLED displays, buttons, and sensors, making your project look professional.
Microcontroller Choice: Due to its round shape, this chassis is a perfect match for the Arduino Nano or ESP32 NodeMCU if you want to save space on the top deck for more sensors.
