Naubots go out into the sea, power itself from the sun, and send you back photos from days- and months- long voayages. They can also monitor an aquatory, or may be catch fresh fish or automate kelp farms (depending on installed sensors and actuators).
The cognitive abilities of naubots (on a very primitive level, like stimulus-response) are kindly provided by Ardupilot and the main hardware components follow the RC modelling design principles.
The first naubot code name Zero , released as an open platform with all components available off the shelf and with detailed instractions on how to assemble and configure it provided below.
