suspend Roberts' Linkage and measured it' resonant frequency
We suspend Roberts' Linkage from IP top (image: Fig1, picture: Fig2). The parameters were as follows.
| high [m] | 0.4 |
| weight [kg] | 28.73 |
I also measured the power spectra with using Photo displacement sensor(Fig3). During measuering, we locked IP physically using meal fitting.
I attached the results (Fig4).
I can realized that there are two peak. These peaks are also from resonant frequency.
I thought it from difference between wire lenghts.
