This study proposes a method for serving curry with a robotic arm as part of research on cooking robots, aiming to achieve a specific ingredient ratio. The system serves the curry in several portions, and with each serving, it detects the ingredients in the portioned curry and generates the next serving motion to match the target ratio. A camera attached to the tip of the arm is used for recognition, but since the curry roux is opaque and not all ingredients are visible, the system stirs the curry while recognizing the ingredients. The proposed method was implemented on an actual robotic arm, and its effectiveness was verified through experiments.
