Abstract : The spring roll is a quintessence of Vietnamese cuisine that is enjoyed by many different cultures around the world. Nowadays, there are 3 types of spring rolls in the markets: Rice paper spring roll, Bia spring roll, and net-wrapper spring roll. As of now, net-wrapper is either manually made or produced on semi-automatic machines, which only automate the forming process, so that workers are still needed in the production process. This study deals with the design of a robotic manipulator that connects to the semi-automatic machine to take the net-wrapper out of the mold instead of manual operation. The experimental results with the developed prototype demonstrate the effectiveness of the proposed design. This study contributes to improve the semi-automatic production and improve productivity from 28% to 80% depending on the net-wrapper’s diameter as well as workers’ working conditions. This new solution will greatly contribute to food industries in the world as well as a working environment for agricultural production in Viet Nam
