Table 1. Experimental conditions of the robot setup.
Frequencies | Angle range* | Number of accelerometers (range in position relative to axis of rotation) |
0 Hz | 0° and 22.5° | 18 (0.13–0.78 m) |
0.05 to 0.55 Hz (steps of 0.05) | 0–90° | 18 (0.13–0.78 m) |
0.60, 0.70, and 0.80 Hz | 0–45° | 18 (0.13–0.78 m) |
0.90, 1.00, and 1.10 Hz | 0–20° | 18 (0.13–0.78 m) |
1.20 and 1.30 Hz | 0–45° | 5 (0.13–0.29 m) |
1.4 to 2.6 (steps of 0.1), 2.8, 3.0, 3.2, 3.6 and 4 Hz | 0–20° | 5 (0.13–0.29 m) |
[*for 0° the bar is in horizontal position and for 90° the bar is pointing upwards relative to the axis of rotation].
