As low birthrate and the aging of the population progresses, labor force is seriously lacking in heavily worked construction sites including material handling recently because it is very difficult to replenish young people according to retirement elderly number. If we can leave material handling work to the robot, the problem of labor shortage will be relaxed. In this research, we aim to develop a two wheels independent driven robot that transports materials, and developed a path following control method by the PID control method, and conducted a simulation to show its effectiveness.
