Re: [Paparazzi-devel] solving vibration problem using better sensors?

[Prof. Dr.-Ing. Heinrich Warmers]

Hi,
for multikopter the use of temperature flow based acceleration sensor  
MXR9500  was a solution.
This sensor has a 17Hz bandwidth.
The question is in  rwhich region lays the vibration generated by the IC 
enigine.
There are some  documentation of damping the sensors with a wood box and 
floan   by the use of  paparazzi..
You can try the old IR sensors. There have no problems with vibbrations.
Perhebs  a easy way to solve your probelm.
