Development of high accuracy position marking system in construction site applying automated mark robot

This Paper describes development of high accuracy position making system using the mark robot and survey system. In the construction process of foundation works, the initial making on the base floor is very important work to set and built the construction materials exactly. However, the making errors were often reported by human error of marking worker. This trouble causes not only the lack of constriction confidence but also the decrease of work efficiency. In order to do high accuracy marking and to reduce the human errors, the automated marking system was developed using mark robot and the survey total station. In this mark robot, the marking device is installed at robot center and the error between mark point and stamp marker point can be modified exactly. Using this marking system, high accuracy marking can be executed. The marking process controlling in automation, the high efficient and accuracy foundation marking is performed.
