RF Triangulation Using a PIC
Hi, Jeebus!
It's been almost two years since this conversation took place, but I just now ran across it. I'm hoping that you (or someone) will see it and reply. I don't know if this website sends e-mail notifications upon replies, so could you also send your reply to

I need some help. I am trying to design a little robot to go from point to point, take some kind of measurement (not important here), and log the data. I could simply tell the robot to go forward 10 feet, take a measurement, go forward another 10 feet, and repeat. But if I did that, there would be no feedback; and the robot could go off course and take measurements at the wrong positions. I was thinking about using radio frequency triangulation (or something comparable) with two known-positioned tranceiver beacons to dynamically provide negative feedback on the robots position, so that it could self-correct and stay on course. The only problem is that I am new to PICs (not that big of a problem), am fairly inexperieced when it comes to serial communication between sensors/tranceivers and microprocessors (again, not that big of a problem), and have NEVER done ANYTHING with radio frequency or triangulation (big problem)!
Okay, so a few questions...
1) Is RF Triangulation the right solution for this problem?
2) What kind of RF tranceiver do I need? Manufacturer? Model #? Cost?
3) How did you accomplish the phase compares, demodulation, and so on to figure out the robot's position?
4) Were you successful with your robot?
I am a 31 year old electrical engineer from Charleston, West Virginia, USA. In my day job, I work for an MEP (Mechanical / Electrical / Plumbing) consulting firm designing power systems for new buildings. As a hobby, I design electronics and robotics. ...If anyone out there has a solution (or any useful information) to my project, please let me know!
Thanks!
