It's been two years since we started with the HYBRiX development!!! Since some months ago we feel that development is finishing and that HYBRiX20 meets almost all the specifications that we said at the beginning.
There are a lot of challenges left to face but right now…
We long ago decided that the controller of the Hybrix20 was going to be a Pixhawk. Some customers tell us that Pixhawk is not the right platform for our product but we would like to work on those few things that are missing to fit a drone of these features.
It would probably be more spectacular a test flight of 4 hours but i was very interested in performing this test because it is very near to real use of Hybrix.20. 4 or 4.5 hours are possible for demonstration test but operational flight time is around 3 hours with light payload to 2 hours for heavy payload.
First flight tests of full automatic flight plan from take off to landing. We are using Tower. You can see the whole process on the video: flight plan generation, combustion engine start, drone arming from the tablet and mission launch.
I want to share our last experience with HYBRiX, a lapse time of a 3hr and 10min endurance flight test. As far as I know it is the longest flight time for a hybrid fuel-electric drone, and I have to say it is not a lab test, but the same configuration we will start selling very soon. We are really excited about this! Please comments…
This is the crazy project that kept us busy lately at Quaternium: a hybrid electric+gas multirotor with range extender, inspired by Hybrid cars, such as BMWi3.
Our goal is to overcome the endurance limitations of an electric multicopter, while keeping the multirotor platform we are so enthusiastic about. This VTOL UAV has 2.5 hr estimated flight time with payload, and around 4 hours endurance…
The sUAS market for surveying applications are dominated by fixed-wing aircraft instead of multicopters. The reason is obvious, the multicopters have very short flight time and can not run long flight…
I am looking for use google earth as ground station.
i have download this program.
it is easy to interface to any application:
GooPs can receive data from other applications via a TCP/IP socket. GooPs listens on port 51234 for messages containing NMEA data.
and another similar program:
it demostrates it is possible but
Where can… Continue
Centripetal force compensation is a algorithm than compensate centripetal forces effect over accelerometers so AHRS could get a correct attitude measurement during large turns.
we are using a simple record player to test centripetal compensation.
Effect of centripetal force could be a problem if the plane stay in a turn for a large time, for example doing… Continue
Ready to make the first flight test with our nanoAHRS. Servos are connected to nanoAHRS and standard receiver are connected by PPM to nanoAHRS. All channels are downloaded in realtime through Xbee PRO.…
I am testing DCM update with PI drift tracking. I am using one closed loop with gravity vector and other for magnetic field vector (3 axis vector), i am comparing measured vector with my local magnetic field vector. it works ok!
i have read than magnetometers can not be used with electric motors, but i have tested this board over a electric plane, and i can see noise due electric motor is very very small, it is dificult to see any effect in algorithm… Continue
