Construction robot (Automated System for Bridge Inspection)

Robot construction has recently been introduced to Korea. Until now emphasis here has been on robots for industry.
Japan has been using robots for construction in inaccessible and dangerous locations
We at EJtech in Korea are fast catching up by introducing the first robot to monitor lower-bridge areas.
We plan to adapt this cutting-edge technology to monitoring tunnels, utility-pipe conduits, drainage systems, and LNG tanks.
