A small survey boat with twin thrusters, GPS waypoint mode, waterproof electronics, return-to-home and manual radio override.
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. 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.
Stable platform with deck space for electronics
Differential drive propulsion
Forward/reverse speed control
Waypoint navigation and heading
Control stack depending on autonomy level
Sealed enclosure with cable glands
Tiny hull, low voltage and simple waypoint demos.
Add temperature, pH or turbidity sensors and log GPS-tagged readings.
Build reliable radio control first, then add autonomy as a mode.
Treat the generated output as a prototype plan, not a certified product. Body-adjacent, high-voltage, optical-energy and mobility builds need qualified review before real-world use.
Yes. ArduPilot Rover/Boat modes are useful if you use supported hardware.
Use cable glands, gasketed boxes and strain relief. Test empty in shallow water before adding electronics.
Switch to manual or hold position slowly. Do not continue a mission blindly.
