“PE-lab” is a project carried out by junior and senior students of the Department of Precision, School of Engineering, The University of Tokyo. We mainly learn three fields of production science, design information, and mechatronics, based on the foundation engineering of mechanical physics, mathematical information, and measurement and control. We have prepared for more than half a year to correspond our project to the Corona era, which is very different from previous years. This project is mainly based on what we have learned in lectures, as well as new technology we have positively learned and applied. “PE-lab” is one of the main events of the Department of Precision Engineering, and students can deepen their relationships by getting together for the May festival project every year.
