Hey guys,
I am working on a school project, where I need to design a boat that will follow a certain path, avoiding obstacles.
My idea is to map the obstacle circuit and then use a homemade small scale GPS system to determine the position of the boat in the map. (The control of the movement of the boat is done already).
To accomplish this, I was thinking about setting up 3 transmitter towers around the circuit (a 2-meter-diameter round pool) and a receiver on the boat.
Each transmitter would calculate its distance to the sensor on the boat, and send it to the computer. The computer would then analize the distances and find the exact position of the boat on the map.
I have already programmed a software, thorugh matlab, to do this calculations. But I am having trouble with the sensors.
I need a precision of about 10 to 20 mm (i.e. the distance measured by the transmitter can have an error of 20 mm max). And my budget is not that high.
Does anyone know a good sensor that I could use? What can I use for the transmitters and the receiver?
I was maybe thinking ultrasound, but I did not find one with the function I needed.
Any suggestions? It will be gratfully appreciated.
Thanks.
