Table 3: Data for the design of deployment scenarios and its corresponding design matrix. Comparative Analysis of Working Conditions for Plant Transplanting Equipment Using Data-Driven Methods  
To examine the most effective operational parameters of the plant transplanter, it is essential to analyze the variations in vibration properties when subjected to various working conditions. To examine the acceleration condition of the lifting manipulator for plant transplantation equipment, three-axis acceleration sensors were positioned on the beam located above the manipulator for transplantation. Figure 7 shows a fitted vibration cloud of the transplanter during horizontal sliding. During a single transplanting session, the test condition involves the horizontal slider of the transplanting manipulator moving laterally. The signal is sampled at a frequency of 2560 Hz, and the RMS value is calculated every second.
