Robots, which are attracting attention as a future strategic industry, are expected to form forward and backward industrial ecosystems across all manufacturing and service sectors and to drive innovation. Robots are divided into industrial robots and service robots. Robots, which have developed mainly in the manufacturing industry, have recently expanded into intelligent service sectors that can provide diverse benefits in daily life such as delivery, care, serving, and patrolling by converging with ICT technologies including sensors, AI, and autonomous driving.
