Indoor Navigation

Hey everyone! I am setting out to program a Hex-rotor to be a pace setter for an indoor physical fitness test here at the Air Force Academy; Basically fly over a track at a certain pace shooting a laser below for participants to keep up with) I am wondering if anyone knows on any working system for indoor navigation based on triangulation that I can use... 

I will be using an APM 2.5 Hexa X build.

We've looked into using an optic flow sensor to look down and follow the lines of the track but since there will be people running beneath it we dismissed that idea. We've also looked into close and far range sonars looking at the walls inside the Field House. This setup seems to be possible except we want a platform that could easily be modified to fly in other indoor setups. The only thing I can find regarding indoor navigation is Kmel robotics work with many IR lights. Although this approach would work, the ammount of IR lights to get this working in such a huge place would be ridiculous.

Any ideas on how I can solve this are welcome!!!

thanks!!

  • You can use a precise (+-2cm) Indoor "GPS": http://marvelmind.com/.

    Here a couple of demos:

  • Yes, I have considered many different options including the ones mentioned. In the end, regardless of whether it is used or dismissed as unsafe, I'd still like to get some sort of navigation working based on small scale triangulation...

    Ya, a flying lawn motor over a bunch of peoples is probably not be good idea. Have you giving any thought to a cable or guide wire system? Simialiar to what they use at pro football games for the over the field camera angle.
  • It's always dangerous to fly UAS in the near vicinity of people. Perhaps try aiming the laser pointer from a fixed position on a micro controller based pan/tilt rigging. Good luck.
