Summary:Making robots capable of pouring can be useful in both service and industrial applications. Considering the importance of controlling liquid vibration in mixing chemical reagents and other industrial applications, we investigated in the this study robotic pouring with the aim of controlling liquid vibration, more specifically, the beer-foam ratio during beer pouring. We propose a vision-based measurement method that can measure the liquid volume with an error of less than 5% in real time. Besides, together with a proposed robot pouring controller, we develop a robot pouring system that can control ratio of beer-foam volume with an error of less than 5% during pouring. The flexibility of the developed system was also demonstrated through experiments using different types of container and beer.
