Pteryx UAV photo mapping from Krzysztof Bosak on Vimeo.



After completing testign campaign and delivering the first examples we haverushed to publish a short documentary.
Pteryx is an UAV designed for civilianuse, together with its mission-oriented autopilot.
Our focus is in reliableoperation and single button interface. basically you have to put UAV on the
rails, select missions with rotary knobs, hold takeoff button until the
autopilot completes propulsion test, pull the bungee lock.
Pteryx can lift800g compact digital SLR in roll-stabilised head, providing superior quality
photography unachievable by other means: Better flying precision than manned
crafts, inaudible electric propulsion, very few parts to break (only 2 control
surfaces, folding propeller).

Endurance up to 120min, parachute landing,protected propeller.
Possible takeoff from hand and manual piloting.
By law,limited to visual range (some 500m) what yields 1km x 1km map.

  • Fantastic work Krzysz. You say lucky guesses, but I am sure it is your comprehensive understanding of the subject matter that allows you to make educated guesses about what will work and what wont.

    I hope the Pteryx is a BIG success.

    @Eric T Photo-stitching in this example was done by microsoft ice. But we have sub-contractors that can process the data, also if the user places reference points on the ground or knows landmark positions. This processing is inevitably very costly if you want to gave a few cm precision map. So on Polish territory you can contact TriggerComposites and we can arrange with airspace authorities and image processing company an operation that otherwise would be more costly and complicated with manned technology.

    @SciFly LOS restrictions in some countries forig moving of the base station. In other countries you can have many spotters so you can fix them on the ground and they can relay 'John, it's ok' secret message. In Poland we did 19km long 2-way photomapping of motorway construction site by following it on a local road keeping within LOS without problem. We didn't blocked any traffic and ATC was quick to grant a permission because weather was too rainy for others to takeoff in the whole area.
  • What program are you using to do the photo-stitching?

    @TJB
    Yes I made a joint-venture with Trigger Composites.
    I needed a serious maker of a mature platform, after stumbling into limitations of amateur platforms.
    So this way the autipilot has been tuned to the platform, and the platform was chosen to be the best for the task (this includes a mix of price and durability). After all those efforts, it appears that we made a few modifications here or there one couldn't do using off-the-shelf autopilot. It will gives us slight advantage now (pre-programmed missions), it will give us even more edvantage tomorrow. If the pracitce had shown a different fuselage woudl be more practical, we could have done it. So far we are really happy how it works together and happy to have dismissed classical landings in automatic mode (difficult to have high endurance, high lift and short landing). In short, a lot of lucky decisions have been done.

    @F PIVOT
    The parachute is made by Trigger Composites. We are doing everythin except small parts that could break:
    standard equipment includes all propellers, servos, motors, ESC (yet we had to reject 80% of existing sdolutions after compatibility testing).
    The parachute itself is not particularly hi-tech, not a single element looks cosmic in the whole UAV, what is difficult is modifying the autopilot to make parachuting operation putting as few stress as necessary, hundred times.
    So we had 80% of good guesses based on good engineering practices, the rest had to be ironed out in tests.
    Yes even paper parachute could work, most probably, a few times.
    Square parachute reduces stress load compared to circular one.
  • Very interesting and nice work! What parachute recovery system have you used? Self-made or purchased from a specialized company?
  • PS - What did you wind up using for your photo stitching if you don't mind sharing?
  • @Krzysztof - Been watching your progress for a year or so. Congratulations! I have yet to really do much with my tech, and haven't really found anyone willing to take a risk here in the states given the regulatory situation. Did you partner up with "Trigger Composites" after you made your autopilot?

    @Thomas
    this is full custom mold just to met the requirements of area coverage, having stabilised head and being lightweight.
    At this price range usually you get a flying model integrated with autopilot, a kind of demo.
    This is not our case.
    Also pls remember this is for daily flying: going to that level personally from diydrones will cost you several times more (years) in your time and tooling.
    Also note the thing has been designed as enabling scaling of the business: the operator doesn't needs to be a man of all professions,
  • Very nice work, I wish you much success for your efforts.
  • It looks nice ... 8.900 Euro is a nice price too ;-)
