This paper describes a development of high accuracy position marking system applying the mobile robot and survey system. In the construction process of foundation works, the initial marking on the base floor is very important work to set and built the construction materials exactly. However, the marking errors were often reported by human error of survey worker. This trouble causes not only the lack of construction confidence but also the decrease of work efficiency. In order to accomplish high accuracy marking and to reduce the human errors, the automated marking system was developed using mobile robot and two survey system with laser range finder and tracking total station. In this mobile robot, the marking device was installed at robot center and the error between right target point and mark stamp point could be modified exactly. Using this marking system, high accuracy position marking on the base floor could be executed. The marking process controlled by the automatic operation, the high efficient and the high accuracy foundation work, was performed.
