VTOL progress with PX4

We were able to make good use of the last few weeks of good weather. VTOL support in PX4 is becoming more and more stable and supports now the 3 basic types of VTOL UAVs:

  • Tiltrotor
  • Tailsitter
  • Standard (non-tailsitter, non-tiltrotor)

In addition to manual flight we also successfully tested completely autonomous flights with transitions on a standard VTOL.

Have a look at the videos:

 

Medical Express

The organizers of the UAV Challenge recently announced their next competition: the Medical Express. It’s not about dropping water bottles anymore, instead the UAV has to pick up a blood sample from Joe at a remote location (Joe’s outback residence) and bring it back home. The landing spots will be obstructed, there will be no glide slope for landing/takeoff. Flight distance from home to Joe’s location is between 20km and 30km. The Medical Express therefore introduces quite some interesting challenges: on-board landing spot detection, remote vertical takeoff and landing, flight corridors for traversal, possible loss of LOS.

We’re very keen on participating again, and we’re already preparing the range finders for ground distance detection ;). Stay tuned!

We’re going to Australia!

Joe Finder Tests and Deliverable #3 Flight Hours Achieved

Last Sunday we reached another milestone accumulating a total of 6.5 hours autonomous flight. With this we met the main requirement of Deliverable #3 for the OBC requiring 5 autonomous hours with at least one flight longer than 30 min.

Following this we moved onto the next phase of testing our “Joe Finder” onboard vision system in the Viper. The initial results were looking quite promising.

The following video shows a compilation of the flights from the day including some sequences created from the onboard downward facing imaging camera.
