RC Backyard Robot

RC proto outside: The goal of this project was to test the capability of an RC-controlled robot. Its future goal was to become a lawnmower — but as most of my projects go, it ended up not finished lol.

📐 Project Diagram

Notes:

• This project is pretty old — I think the wheel positives/negatives went directly to the controller.
• The wheels run on 24V from two batteries in series, routed through the controller.
• The motor driver isn’t a typical H-bridge. It’s a higher-voltage/amp unit rated for 24V and the motor draw.
• Motor controller was sourced from RobotShop.
• Wheels and motor are wheelchair motors. Sourced from ebay.
• Electric brakes were removed from wheelchair motors.
• Frame was built by Father-In-Law, using scrap metal. Welded together.
• High voltage/amp motor Controller was RC/signal ready.

🧰 Parts List

• RC transmitter (plane/car style)
• Multi-channel receiver (steering, throttle, etc.)
• Two 12V batteries in series (24V)
• Wheelchair motors or other suitable DC motors
• Sturdy chassis

💡 Code

// None needed. Control is via RC transmitter/receiver.

If you want custom behaviors later, add a microcontroller (Arduino/Raspberry Pi) between receiver and motor controller.
