The experiment with different vibrating masses vibrating into different directions showed a very good detection sensitivity of low vibrating masses, down to 0,5% of the payload range. This means that with the Stewart platform capable to move 20kg, a mass of 100g had been detected, if it was vibrating in the predefined frequency range between 5 and 18 Hz.

Moreover the verification of the theoretical approach gave an excellent accordance between model and physical setup, in the first three of the six degrees of freedom that were analyzed.

In the final project stage this verification will be extended to all six DOF’s of the hexapod.

The experiment is made public on the homepage of the robotic institute of the Linz University, and linked to echord homepage (see www.robotik.jku.at – research – echord).

We also participate at the conference OPTIROB 2012 in Romania, Mamaia which is held from the 21 to the 23 of June. (http://www.wix.com/olaruadrian/optirob2012)

The paper title is “A Pneumatically Driven Stewart Platform Used as Fault Detection Device” and is printed in the journal of the conference.
