5. NAVIGATION INSTRUMENTS
In days gone by navigational instruments would have included: Charts, Dividers, Parallel Rule, a Slide Rule, Nautical Almanac, Tables, a Magnetic Bearing Compass, a Sextant and a Marine Chronometer.
These
are the traditional tools of the trade by which nautical navigators and pilots
would find their present position and determine speed and direction to be able
to arrive at the next port of destination.
Imagine if you will that the modern tools of the trade are no different to their electronic counterparts, such as GPS replacing the compass. The main difference is that modern electronic instruments do away with the need for paper charts, making all the calculations for humans in a paperless helm.
The bit that made all the traditional instruments work is the human brain, but without the instruments, the human brain is unable to solve the navigation problem with any degree of precision. With our brain though, we are able to fashion tools. We are tool users, one of the skills that roughly two million years ago set Homo Habilis above his competitors.
It could be argued that the development of autonomous craft, is just another stage of our obsession with tools. This time taking ourselves out of the equation. Letting the robot vessel do all the work for us.
That is in essence what autonomy is all about, replacing the need for a human to connect the dots.
MODERN EQUIVALENTS
The ArduPilot Mega 2.5 is a complete open source autopilot system. It allows the user to turn any fixed, rotary wing or multirotor vehicle (including cars and boats) into a fully autonomous vehicle; capable of performing programmed GPS missions with waypoints. This version comes with the RC/Servo connectors unsoldered, so you can choose between straight or right-angled ones, both of which are included.
