The goal of this study is to develop a learning system for car mechanics by examining the techniques used by craftspeople. In this study, the striking motion of an expert's hammer during the sheet-metal molding process in an automobile repairing process was analyzed and compared with those of non-experts. Using a three-dimensional digital motion analysis equipment and a fingers pressure measurement system, we measured the movement of skilled and unskilled individuals while repairing cars by using the sheet metal molding process. The results showed that experts used a lower number of strikes compared to non-experts as the hammering time and hammering strikes energy increased. Additionally, experts used mainly fingers for gripping a dory.
