Quaternium HYBRiX at XPONENTIAL 2017

Hi Guys!



This year we will be at XPONENTIAL 2017 (May 8-11, Dallas). We have a small booth for startups. We are very excited because it is the first fair we attend in the United States.…

Rugerized flight controller with pixhawk inside

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.

The…

2 hours and 5 minutes test flight with maximum takeoff weight

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.

Lately many customers are telling…

Flight test of HYBRiX multicopter with a fully automatic mission using Tower APP


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 hope you like it!

3hr 10min endurance test with HYBRiX quadrotor by Quaternium

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…

Successful flight test of hybrid gas+electric VTOL UAV: HYBRiX

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…

Huge quadcopters can be attractive alternative to fixed wing for mapping and survey

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…

Probably the smallest arducopter frame?

A long long time since I published last time, I'm drawing something fun and I thought you would like to see it!

It is a small frame all cnc machined from delrin sheet for 5" propellers. It seems a crazy project but…

Simple way to use Google Earth as ground station.

I am looking for use google earth as ground station.

i have download this program.





http://goopstechnologies.com

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 testing with a old record player.

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

Testing inertial attitude estimation in my hardware



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

Bidirectional RC transmitter with ARM7, Xbee PRO, Bluetooth and a PDA (2)



I am working in my bidirectional transmitter. i has built parts in plastic with my hobby cnc machine. it looks very technical device!!!



i have not received PCB yet.



i post some pictures of not finished assembly.



We are testing XBee Pro Series 2 with ZB firmware now, it seems than 5 Kbytes/sec is possible. We publish transfer rate speed as soon as we finish testings.

Hexarotor, folding multirotor helicopter



It is a folding 6 rotor helicopter, inspired in X6 helicopter.



i would like to build in polyethylene technical plastic, it is light, shock resistant and easy to work with my cnc mill.



propellers are in a circle of 500mm diameter, i think best option in order to use standard RC parts is to use 6 x 12" counter rotating propellers.



3 (counter rotating) propeller of 12" have an 8% more surface than 4 propellers of… Continue

Bidireccional RC transmitter with ARM7, Xbee PRO, Bluetooth and a PDA.



Hi,



I am working in this project, it is a bidireccional RC transmitter.



Sometimes, i think than conventional transmitters start to have no sense for uav projects



This is a proyect with a small board with ARM7 (NXP LPC2xxx) and a Xbee PRO with 60 mW (similar performance than standard transmitter) and a Bluetooth module to connect with a PDA.



This board have 9 analog inputs for joysticks, and other… Continue

nMine UAV Controller, more hardware options than anybody could need!!!

Hi, I would like to present my project, i know there are a lot of uav projects but i think it is a amazing balance of price, performance and simplicity! It is based on OLIMEX E2468 board and Sparkfun sensors.



Features

4 Layer board with ground plane for high noise immunity I/O Connectors:


- 8 x Servos - Standard pitch 2.54mm

- 4 x speed input (for sensors, motor RPM, or PPM capture)

- 2 x CAN BUS with transceivers - Header 2.54mm

- 10 x Analog… Continue
