There’s absolutely nothing quite like the sight of a plastic box merrily sailing its method around a lake to symbolise how easy it is to get going in autonomous robotics. This isn’t a task we’re blogging about because of technical excellence, but purely because viewing an autonomous tupperware box browse a lake by itself is surprisingly compelling viewing. The factor that [rctestflight] built the vessel was to evaluate out the abilities of ArduRover. ArduRover is, obviously, a flavour of the incredibly popular open source ArduPilot, and in this case is operating on a Pixhawk.
The hardware itself is intentionally as simple as possible: 2 small motors with RC automobile ESCs, a GPS, some power management and a telemetry module are all it takes. The telemetry module permits the course/mission to be upgraded on the fly, as well as sending out diagnostic data back house. Initially, this setup carried out poorly; low GPS precision combined with a high frequency control loop piloting a device with little inertia cause a very irregular course. However after using some filtering to the GPS this enhanced considerably.
Despite the simplicity of the setup, it wasn’t immune to flaws. Seaweed in the prop was a reason for some demanding viewing, not to point out the absence of power needed to sail versus the wind. After these issues caused the boat to drift off course past a neighboring pontoon, public sightings ranged from an unlawful authorities drone to a canine with lights on its head.
If you wish to utilize your self-governing boat for other functions than frightening the general public, we have actually blogged about vessels that have been utilized to map the depth of the sea bed, track aircraft, and even cross the Atlantic
