It is only a design exercise with a wingspan of 1640mm, and a lot of space for electronics and batteries and very easy access to electronics. Last image…

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 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

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.

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

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

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
