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.

Aiming at laborsaving of the conveyance work of interior materials, the authors developed the automated conveying system which can respond to change of a situation peculiar to a construction site flexibly at low cost. The IC tag signboard which specified the conveyance place is only put on material used on the spot, a diving typed AGV (Automated Guided Vehicle) can load material automatically, and this system can convey it in the purpose position. Moreover, since it can set up simply only by using magnetic tape for a conveyance course and sticking on a floor, the course change by re-covering is easy. Thereby, compared with the conventional carrier system, conveyance work could be economized to about 1/2～1/3, and it checked that workers could be collected to skill work.
