Students in this course will learn about advanced issues within mechanical engineering through experience. Students will get first-hand experience with machines, conducting experiments on plastic working, motion control, non-linear vibrations, self-excited vibrations, combustion, natural convection, aerodynamics, nondestructive inspection, thereby deepening their understanding of mechanical engineering. Specifically, students will conduct experiments on plastic working and deformation properties of aluminum, analysis and motion control of a robot arm mechanism , characteristics of non-linear vibration systems and self-excited vibration systems, combustion, observation of natural convection, measurement and visualization of aerodynamic characteristics of wings and nondestructive inspection using ultrasonic waves.
The main aim of this course is both to deepen students' understanding of mechanical engineering and improve problem identification skills, implementation skills and solving skills by conducting progressive experiments in mechanical engineering. In addition, students learn teamwork, leadership, communication skills, data collection, processing, and organization methods, observation methods, and how to write reports through these experiments.
Students will acquire the following skills from taking this course.
1) Skills for explaining advanced aspects of mechanical engineering that cannot be learned just from classroom lectures
2) How to run experiments on advanced topics in mechanical engineering
3) Critical thinking skills, practical skills, and problem-solving skills
4) Teamwork, leadership, and communication skills

At orientation in the first class, the instructor will explain the frame of mind and suggestions for students' experiments, as well as composition guidelines for experiment reports. From the second class on, students will be divided into 7 groups, and each research topic will be worked through. Reports must be submitted by the deadline. In addition, students are required to carefully read the experiment manual in advance to ensure experiments are run safely and smoothly.

Experiment text is distributed by instructor.
Students are required to attend all classes and perform all experiments and to submit all reports. Students will be comprehensively evaluated on the content of experiment reports, as well as activeness and seriousness when participating in experiments and exercises.
Students are required to have successfully completed Basic Experiments for Mechanical Engineering（MEC.P211.A）,Advanced Experiments for Mechanical Engineering（MEC.P211.A）and Advanced Experiments for Mechanical Engineering (MEC.P331), or have equivalent knowledge. The number of registering students will be limited because of experimental apparatus and safety reasons.
