Hi there!!
first of all i want to say that I am noob in Programming ... I managed to do only some
basics (reading pwm controll an ESC etc etc).
A lot of people are searching for a funktion that is called RTH for rc cars and boats.
This funktion is very very popular in Greece where I come from.We use it for fishing.
A lot of boats are lost because a signal loss or when the waves are too high.
Many people are searching for something cheap but the market in Greece isnt so cheap as many are thinking.
Only the autopilot costs 60 euros (apm ,pixhawk etc) and a lot of them cannot afford it!!!
Thats true!!!!They cannot afford it!!
So my question is..... can someone make a code to help me make this so i can translate it in Greek so many people can do this cheap.
I am thinking using an arduino nano which is cheap will do the job.
i found a lot of tutorials on the web but they are to complicated for me.
I am not intending to earn money for this... its not what i want.
I have already my boat with a pixhawk.I am lucky that i could afford it.
thanx a lot

It's not the code that's making a device expensive.
It's always the hardware. And the waterproofing and ruggedisation of the thing. And making sure it Just Works (e.g. recovers connection when lost due to waves).
Thanxs for your reply.
So how much costs something like this.
Mostly used are.:
1 motor
1 servo for steering
1 servo for fishing line automatic release
Transmitter mostly used is ppm based
The funktion is:
We guide the boat manually to the position we want its usualy 300-400m away. With one of the transmitters switch we release the fishing line and then we guide the boat back again manually. A lot of times we lose signal or view of the boat.In this situation we need the boat to self release the fishing line and start to come back to us. When we have signal again we take controll of the boat again manually.
Can you write a code?
And how much will it cost.?

Without actual specifications or (better) specific part numbers, no price can be given.
This will need also need a controller (Arduino), appropriate power supply, other supporting hardware (such as drivers for the motors and servos), the transmitter, how to connect it all together, and the case.

This implies the boat knows where it is (GPS receiver), where you are (well - last known location - GPS receiver in your handset or the boat stores a "home" location from its own GPS), and which direction the boat is heading (compass).
Can you write a code?
Not before I have the actual hardware in my hands. With that, I'll be able to do so. It's quite straightforward as long as you don't care about safety measures such as collision avoidance, and you make sure there is a clear line of sight and clear water between the home location and the current location of the boat. Also you have to design the boat so that the fishing line can never get stuck in the propulsion or steering system (a water jet would be safer than external prop).
And how much will it cost.?
Depends on all of the above.
60 euros is very cheap, considering that computer programmers charge far more than that per hour. We occasionally get posts like yours - people wanting to get a reimplementation of some commercial product because they think it will be cheaper. This is almost never the case. Commercial products take advantage of economies of scale. Assembling a prototype - which is what you are attempting to do - is always far more expensive.
