For those of you that have a CHR-6D IMU, I thought that you might be interested on the testing I have done on a quad-rotor. I basically took the open source software that comes with the IMU and implemented Bill's DCM algorithm on the on-board STM32 MCU. Then I interfaced the IMU with the quad-rotor controller (I had this done a while ago) and was able to have a fairly stable flight. It is not perfect but definitively usable. To reduce the effect of vibration on the sensors I had to encapsulate the board in gel.More information and the DCM source code for the CHR-6D can be found at:http://vrhome.net/vassilisRead more…
