So, when I tell to anyone about m project, they ask me about the pendulum and how I plan to solve it. Really? At fisrt I was not worried about this problem, I calculated all centers of gravity(CG), and it's ok.  But now, when I think about the vibration and others interferences.... yes, I will solve this.

I begin with the idea of a pendulum and his lenght "L", and I considered to use a dual pendulum to make a opposite force. But I'm don't convinced that's will run well.

With this problem, I remembered of the Taipei 101 tower and his anti seismic system.

I have the same problem but upside down.

Now, I have a concept to how to do this.
