IMAAB stands for 'I Made An Autonomous Boat'.

I work in a university engineering department in the maritime field and we operate a BlueRobotics BlueBoat. While I love it a lot and am amazed at how well it performs, it is sadly out of the price range for most individuals, schools or university students wanting to do a small research projects involving maritime autonomy. So I thought I would build my own version, do it cheaply but reliably, and my starting point was pretty much just using materials and parts that I had lying around in my workshop.

I will start by talking about how the current system works and then gradually add components to achieve autonomous navigation using GPS, basic sonar for depth measurement, various onboard sensors and radio link to send data back to shore etc.
