An object of the present invention is to provide a thermal spraying robot system capable of automatically determining spraying conditions according to the shape of a workpiece. Shape data on a workpiece ( ) and material data on a thermal spray material are entered by operating a data input unit ( ). A spray condition database stores a plurality of spray parameters for kinds of thermal spray materials and for qualities of sprayed coatings. A path calculating unit ( ) selects values of spray parameters from the spray condition database ( ), and then calculates a path for a thermal spraying gun ( ) according to a predetermined program on the basis of the shape data on the workpiece and the selected values of the spray parameters. The path calculating unit ( ) decides whether or not a thermal spraying operation can be carried out by moving the thermal spraying gun along a calculated path. If it is decided that the thermal spraying operation is feasible, a thermal spraying apparatus carries out the thermal spraying operation in which the thermal spraying gun is moved along the calculated path.
