Smart Factory: developing a strong production network

We are moving toward unmanned automation. We applies the latest advanced manufacturing techniques to achieve our smart factory. All our facilities are connected on our own developed IoT platform, which provides a real-time visual analysis of production. Moreover, remote monitoring with 17 network cameras in Head Plant and Nara Plant allow us to observe the performance constantly even in unmanned operation at night. Also, based on the collected data, we optimize our production schedule and make adjustments to increase operation efficiency. In addition, we are striving toward to unmanned automation in assembly lines by the latest technologies for example, introduction of humanoid robots.
