For all those who fly RPi multi-rotor =)
Latest Activity: Feb 25
This group does not have any discussions yet.
All moved into a new home and now Quad-FU is back online =)
We now have GPS guidance and Eflite Park 450 motors on hand made motor mounts.
Thank you, i`ll try.
Do you know any OpenSource software for RasPi-based copters?
Does everyone else heve any progress?
Sorry for the delay. I'm in the process of moving/unpacking at a new place.
Now a days we have an xbee pro for rf / controller input. In addition we use hostpad and connect to the quad's wifi hotspot.
For your camera you might like mjpg_streamer
You can use VLC on anything connected to the hotspot and stream your video.
Hi. I finished to build my copter yesterday. And i broked all propellers :)
I have the flight base now and can start integrate RasPI into my copter.
I will use WiFi for the communication and webcam for FPV.
Also i will use existing MultiWii for copter stabilization and basic control.
ReneeLov3, what do you use for the wireless connection?
Do have any progress with camera? I tried to stream it but i had errors.
So propeller upgrades will be in tomorrow. During my down time I worked with a couple of voltage regulators and found one with half the current draw and more built in protection over the NTE regulator previously used.
Also adding control buttons to operate the quad with or without a computer. Since its still running on WiFi control we will probably make an iPhone and Android remote control application (seems fun).
I'm also working on some dynamic PID control algorithms because as much fun as I have playing with PID gains =/ I much rather let the quad continuously monitor and adjust itself for maximum stability.. wish me luck.

Our build here started off as a budget build. For anyone getting started with flying their RPi there are a few things I had to expand my knowledge on:
I2C communication on RPi for reading Wii Gyro and Accelerometer data.
SPI communication on RPi so we could send throttle data for each motor to the micro controller creating the PPM to drive the ESCs.
Instead of a RC remote we communicate with the quad over WiFi by sending UDP packets from an application we designed. This also allowed me to use a PS3 controller (with internal joystick modifications) to fly and test with.
Also the data structure of the Wii communication in pass through mode to interpret the sensor readings.
Hope this helps.. If it is all too basic or you have more questions I'll try to help.
