Problems solved by technology
[0010] However, if the processed portion of the transmission case is automatically visually inspected by using a camera, it is impossible to perform perfect inspection of the different processed portions with only one set of cameras because the transmission case has a three-dimensional complex shape
[0011] Therefore, although it is possible to subject different machined parts of the three-dimensionally complex transmission housing to vision inspection by using multiple robots each equipped with a vision head, vision inspection may cause problems due to the increased number of robots and Increased initial investment due to the installation space of the fixed inspection equipment and the increased number of quality inspection cycles
