Irrigation systems

This irrigation system features a base unit with a retractable hose connected to a mobile sprinkler. The mobile unit has an internal water channel that feeds water to spray holes on its body and through its wheel supports. As water flows, it drives impellers on the wheels, propelling the unit along a guide path while it waters.

Why it matters: Filed before widespread advanced manufacturing. Custom water channels and impellers are now easier to prototype and produce, potentially lowering development costs.
