Abstract
The purpose of this study is to make a model of two-link flexible robot arms. For this purpose, we used a modeling method called an 'extended reduced-order physical model (extended model)' that is able to express the motion and vibration of flexible structures. The model of the two-link flexible robot arms is made of a combination of the model of each link. The construction of each model is applied to the extended model. To connect each link, the constraint addition method is used, creating method of an equation of motion in multi-body systems. The model of the two-link flexible robot arms agrees qualitatively with the results obtained by the experimental device.
