An autonomous boat is one of the more forgiving outdoor robots because it cannot fall over, but waterproofing and recovery matter.

An autonomous boat is one of the more forgiving outdoor robots because it cannot fall over, but waterproofing and recovery matter. The first build should run on calm ponds or pools, stay slow and always keep manual radio override.

Use twin thrusters for differential steering instead of a rudder for the first version.

Use twin thrusters for differential steering instead of a rudder for the first version. Navigation can be GPS waypoint based, with a compass for heading. Add return-to-home on low battery or signal loss before trying long missions.

Design variants

Pool test boat

Tiny hull, low voltage and simple waypoint demos.

Water-quality survey boat

Add temperature, pH or turbidity sensors and log GPS-tagged readings.

RC-first boat

Build reliable radio control first, then add autonomy as a mode.

FAQ

Can I use drone autopilot software?

Yes. ArduPilot Rover/Boat modes are useful if you use supported hardware.

How do I stop leaks?

Use cable glands, gasketed boxes and strain relief. Test empty in shallow water before adding electronics.

What if GPS drops?

Switch to manual or hold position slowly. Do not continue a mission blindly.
