YouTuber builds a tortoise bot based on Arduino that is 7 times larger and still navigates autonomously

UncleStem built a turtle-style Arduino robot about seven times larger than the original design.

The oversized bot uses salvaged 24V ride-on toy motors, custom parts, lawn equipment wheels, and outsourced laser-cut acrylic panels.

He also scaled up the controller while keeping the same basic sensor-based obstacle-avoidance logic.

The project shows how a simple Arduino educational robot can be creatively adapted into a much larger autonomous machine.
