I'm trying to reproduce this in Inpsire Motion: https://www.youtube.com/watch?v=gnn21smGVrQ

So far I have achieved this:

How can I make act more like in the example video? Now I'm using oscillating actuator that is oscillating in 70 Hz in 10 mm (-+ 5mm). Sample rate or Output rate is 2000 Hz. I'm new in motion and inspire, so any comment is good.

    Hi Karli,

    First, please check gravity direction

    Secondly, change motion excitation (can change amplitude, frequency,...).

    Thanks.

    The gravity is in right direction. And if you mean by "motion excitation" the actuator profile, then like I said, I tried different frequencys and amplitudes, but still can't make it.

    Maybe it is because of the flex joints. Have to test more...
