To cope with labor shortages due to low birth rates in the 21st century, and create friendlier production systems, we propose a robot system assisting production in flexible manufacturing environments, where offline robots replace or reduce human labor on the shop floor. Offline robots conduct aid or service tasks for online robots operating on production lines or sites. We analyze conventional automatic production systems using robots, propose a robotic production concept using two types of robots, present ways to implement the proposed concept and technical results, and discuss fault recovery using offline robots and peripheral technology.
