"A couple of tips:   Gyro integration speed is critical to stability (400Hz is reasonable for an 8bit micro).  Drift correction can happen at a slower rate to save computation time (~100Hz).   You have to translate Mag, and Accel…"

"I think you're using a raw accelerometer, these things are not accurate and have a lot of drift, to solve the drift problem you will need some sort of anchor, like a megnetometer, which is very slow but relatively accurate. In MPU6050…"

"My experience has been similar Evorowy. Accelerometers and magnetometers are extremely noisy and gyros drift.That's just a fact with any of those that isn't thousands of dollars each.There's also…"

"Hello.Thanks for your replay.After lecture of most pitch,roll,yaw I managed to write rather simple fc (base on brokking complimentary filter) but it still contains huge drift. I will try to add some of gathered date to ilustrate that problem.Data is…"

"I have tried all these things and when it comes to noise there is a lot of it. Did you try building the self balancing robot.  It's not as easy as it looks.  The math needed is the same math you need to balance a copter but it only…"

"Hello!Thank you very much for this well of information.I've tried to use Kalman Filter with the following code:http://pastebin.com/FgN67GqmAngle, which was then produced, wasn't really good (on spirit level it shows pitch correctly but the…"

Homemade FlightController.

Hello and welcome everyone!Some time ago influenced by DJI Phantom I started to build my own Quadcopter.To understand the basic principles of aerophysics and RC I started to build my own FlightController based on Arduino Mega 2560 r3, Pololu AltIMU v5 and FlySky iA6 Receiver.Working with RC Receiver was quite a good feeling, it wasn't that hard to understand.However, working with the gyro, accelerometer and magnetometer is painful.I surfed the web for about two weeks and didn't found anything…See More
