CPW Posted June 26, 2006 Report Share Posted June 26, 2006 Long story short, I've been wanting to make a system to locate a 1/28 radio controlled car on my driveway and show its position on a chart/graph in a computer program. Its not really that complicated, but I need some help with the calculations, logic, etc.At first, I decided I would put IR emmitters on the car and have IR receivers located around the driveway that would measure the strength of the IR signal, and calculate the position based on that using trilateration. I didn't think it would work well enough though, so I decided to change my plan.Next, I thought I would do the same thing with RF transmitters and receivers, but this time I would place the transmitters around the driveway and have the receivers on the car so that in the future I could add the capability to track more than one car at a time, since each car would calculate its own position based on the strength of the RF signals it would receive from the transmitters located around the driveway.BTW, I am only trying to calculate a 2d position. Z would always be 0, so there is no need to go for 3d.I have a few questions, though:1. Which would be the better way to go, IR or RF?2. Trilateration uses fixed distances, which I can not provide since I don't have a way to calculate distance. I can only provide the difference between the strengths of the signals. I found something called multilateration. Multilateration uses relative signal strengths, so it should work, Quote Link to comment Share on other sites More sharing options...
