Autonomous quadcopter homes in on radio signals

From Northeastern University. Anybody know what autopilot platform this was based on?

For their senior cap­stone project, North­eastern elec­trical engi­neering stu­dents Cameron Olean, Ben Leathe, Tim Hickson, Chase Hath­away, Dan Petrillo, and Andrew Barada, devel­oped TRAQ—an autonomous quad­copter that uses a unique four-​​element antenna array to locate and nav­i­gate to the source of a radio signal. The quadcopter’s poten­tial appli­ca­tions include dis­aster relief, sur­veil­lance, search-​​and-​​rescue, and stolen goods recovery. The quadcopter’s autonomous nature also enables mul­tiple crafts to coor­di­nate their move­ments and pro­vide greater loca­tion accu­racy. The team devel­oped TRAQ under the guid­ance of fac­ulty adviser Bahram Shafai.

You could also use it to track tagged animals and get a picture of them.. granted you probably want a larger flight time and distance than what a quad copter can provide.

Yes - very interested in this.

I'm tracking them down now!

antenna size (if using VHF) might rule out wildlife work but will see ....

The comments on the video are interesting.

In the sense of how many people view drones, and this type of research. These guys are developing cool new technology, and comments speak of NWO, and these thing eventually hunting down our grandkids.

You see this tech on the top of Police cars, its what the 4 antennas are an Adcock antenna. As MJ says the antennas would be prohibitive in size at current collar frequencies. There is some great open source work kicking about for this and we plan on having a vehicle setup for when our GPS collars revert to traditional jobs (if the gps fails)

speaking of your work Gary  .... about time for another update??

Yes, just received another airframe and doing some more thinking so will add more over the way soon. How is your project going?


Because you asked, I checked the collars and the sixth cat to be caught which was hiding over the hill decided to sun itself on top a hill this afternoon! Hooray. Updated the map
