That's just standard ESC tones. It says the ESC hasn't been armed yet. The way they work is that you have to give them full throttle to arm them, and then bring the throttle down. Only then will they control the motor. This is a safety…

Strange sounds from my ESC...cannot control over a simple connection

Hi all guys,                 I have a very strange problem.I bought an ESC to control the motor of my electric model, and I connected evertything to my Autopilot, but I realized the ESC makes strange noises and cannot understand which is the source.So...I thought maybe something wrong with my autopilot, with the code itself.... but connecting the same output to a servo works greatly....even with and oscilloscope I can see perfect squared waves from my autopilot...So I realized a simple program…See More

Anyone has an experience to branch it to ArduPilot Mega?

Hi Dave, Let me clarify. Lets suppose that you have an IMU with only gyros and acclerometers and that the IMU is level and stationary. If you are using the DCM algorithm with a PI feedback controller, it will achieve a perfect lock for roll and…

"You can use either Kalman or DCM to somewhat reduce the gyro drift if the IMU is tumbling, but you cannot drive the drift to zero, and the technique does not work if the IMU is not tumbling." Hi Bill, I don t understand... do you mean:…

Dave, In the general case, you need a yaw reference to correct for the Z gyro drift, such as a GPS or a magnetometer or both. You can use either Kalman or DCM to somewhat reduce the gyro drift if the IMU is tumbling, but you cannot drive the drift…

GUI for tuning Kalman Filter

Posted on February 21, 2010 at 8:00am 17 Comments





Fine tuning of our Kalman IMUs is one of the most important step to be done in order to get the IMU ready to fly.

And a good tuning begins from "the table"...



Since one month I created a small application, written in java, multi-os, open-source, ready-to-use intended for studying, tuning, debugging your kalman application without any particular need.

It is able to get datas from the serial port (incoming data from the… Continue
