I want to build a solar powered boat that can motor, unmanned and self controlled, from Australia to New Zealand.
I built a prototype to test out boat construction, navigation, steering and communication and monitoring.
Cayenne allowed me to monitor the vitals of the boat, as well as being able to take control if necessary
The boat uses arduino cpus and programs for the various functions, as well as GPS and eCompass modules
Data from these computers is sent by radio to a shore station, where it is uploaded to Cayenne for display
I can also send data back to the boat to control the motors and thus the steering
