Waypoint Gps Navigation for UAVS with Arduino
15.12.2007 at 05:35:28

Hi everybody, I’m the Arducopter creator, and now I finished the waypoint navigation for Arduino… Yes.. You say to Arduino the coordinate where you want to go, and Arduino will show the direction (degrees) and the distance to your objective. Obviously you need any GPS receiver with NMEA sentences. Ok I took this example:

http://www.uavs.net/Waypoint-Math.pdf

and then a wrote a code for Arduino and everything works perfectly. The big problem is that my explanation is in Spanish, if anybody wants to translate it ill appreciate, thanks

Source Code for arduino: http://jordii07.googlepages.com/navgpsV1arduino.txt
tutorial and explanation here: http://gizmobits.com/ardugps/

By the way i able to read with Arduino the GPS data from Flight simulator 2004, and simulate the GPS (is very accurate) , and using arduino to control the airplane with the nunchuck too, all the "How to" is explained in spanish Tongue

sounds great! hopefully someone will translate your tutorial.

i'm wondering if an arduino quadcopter was possible (see mikrokopter.de (german project page), they're using an ATMEGA644 for their flightctrl-board).
did you look into this option or do you want to stick to your helicopter?

i asked a friend who's currently visiting korea to see if he can get me some brushless dc-motors plus controllers as these are quite expensive here... hopefully he did not not forget about me

we should have a forum fork for aerial research and get arduino into the air! navigating autonomously Roll Eyes

great work!

sorry for going off-topic, but brushless motors/esc's are quite cheap here: http://www.unitedhobbies.com

In case your friend forgets you Grin

Ohh yes, i readed it like 3 times jeje, actually the technology they use are infrared sensor like this: http://paparazzi.enac.fr/wiki/index.php/Sensors
, they use the IR to generate a virtual horizon to stabilize the helicopter, is better than accelerometer (alone), because the rotor vibrations make interference and the heli lose control.
Another option to create a virtual horizon is to use a combination of gyro's and accelerometer with kalman filters like this: http://tom.pycke.be/mav/92/kalman-demo-application
I able to do the same with arduino but... right now i dont have MONEY.. maybe santaclus bring me something Embarrassed

. But someday when is done, for sure ill post it... Roll Eyes

NO, but i used a lot of simulations like GPS simulator http://www.sailsoft.nl/gpssimul.htm combine with Google Earth PRO, and is very accurate, ill try to make a example video, to show that is 100% true.. Wink

For example you program you destination in Arduino, then in GPS simulator you put were you suppose to be (current position), then the arduino receive the nmea data, and display the heading. Then with GPS simulator you put the heading, and then the SPEED, and start moving directly to your destination (showed in google earth PRO).. Pretty exacting the first time i saw it working Cheesy
