So the electronics deck on my RC car is hard mounted to the chassis. When the robot vibrates so do all the electronics including the IMU. This points tons of noise into all the channels of the IMU. I have talked to a few of my mechanical friends and they all have come back with various suggestions including floating the IMU in a bottle of glycerin. Like that would work on an RC car!
I think I have a few ideas on my own. First I think I need to stiffen the electronics deck. I could see it flexing like crazy under the vibration. Then I need to modify the hard mount system with perhaps a rubber band mount. And lastly I am going to need some kind of viscous damper. Here is where I am stuck. Perhaps I can find a VERY light duty air filled shock absorber.
So here is another job for the todo list.
