In this paper, we proposed a horizontal-transfer robot system was designed using a hydraulic system and some electronic sensors, and a synchronized control method was applied to control each robot. An alignment system was also designed to align between the rail and a truck. The proposed system will be useful as an intermodal transportation system that is significantly considered an enhanced technique or future railroad logistics. The system can simplify the complicated job process in
