The first part of the bench automatic round-trip control lab report should be clear about the purpose of the experiment, that is, the goal and significance of passing the experiment. Next, the experimental principle should be introduced, including the basic principle of automatic round-trip control of workbench and related theoretical knowledge. Then, the experimental steps should be described in detail, including the equipment used, the experimental operation process and parameter settings. Finally, the report should present the experimental results, including data recording, graphical presentation and analysis of experimental phenomena. Such an experimental report should present the experimental process and results clearly and accurately for readers to understand and reproduce.
