The theoretical base to identify the transfer functions of the vibrating hexapod with and without lose mass was elaborated and is described in milestone 2 (M12)

The experimental implementation and verification of this theory was started in the last month, using vibration sweeps of the hexapod from 0 to 30 Hz.

In the attached movies this movements are visible, first in slow motion, to distinguish all 6 degrees of freedom, and also in real speed vibrating in the vertical direction with a frequency going from 0 to 30 Hz.
(see odeuo_slow.wmv and odeuo_sweep.wmv)

In the next steps these measurements will be repeated with a mounted vibrating test mass, trying to identify it sensorless.
