After getting some more IMUs from Analogue Devices last week, tonight I assembled two more complete units. I was happy to see that everything worked fine out-of-the-box. However, I managed to crack a casing when I pressed down an IMU. The tolerances of the IMUs are a couple of tenth of mm and I guess this unit was slightly bigger than the others. Be aware that this can happen!
Some small comments about new IMUs. First of all, per default they come with a 4-tap low-pass filter turned on. This can be turned off with the set_lowpass_filter_imu.m file among the Matlab control scripts. Also, out of the box, the gyros have rather large biases up to 1°/s. Therefore, the gyroscope calibration routine should be run once to make the system perform better.
