Path planning with a uniform paint thickness distribution for industrial painting robots is challenging. It is difficult and time-consuming to generate a path with a constant paint thickness because extensive trial and error are required. To realize painting paths with a uniform paint thickness distribution without specialized operator skills, it is useful to simulate all painting processes and verify the paint thickness distribution. Therefore, a simulator that can predict and analyze paint thickness is developed in this study. A distribution model of adhered paint ejected from a spray gun is proposed. The distribution model is identified by fitting the actual paint distribution to the model and a painting simulator is developed. The effectiveness of the developed simulator is confirmed by a comparison between the simulation results and actual painting results for a complex structure.

When designing clothes, fashion designers consider drape and movement of clothes as important factors. To reduce the burden on fashion designers and pattern makers and to save costs and operation time in the apparel product design process, development of more realistic dressing simulation system reflecting mechanical properties of clothes was required. In this paper, simple measurement methods of the cloth mechanical properties that can be introduced on-site is proposed. The tensile, shear, bending and damping properties are measured with the proposed simple devices and are utilized to the simulation as the mechanical property parameters. As a cloth model, a mass-spring-damper model where mass points are connected by the springs and the dampers is constructed in the simulation system. To verify relevance of the dressing simulation system, the simulated results are evaluated by comparing with the results of real models.
