We develop a small NC milling machine based on the concept of a micro factory. We try to manufacture this machine for using even in the laboratory where there are lot of amateur machine operators for getting trial machine parts. The small NC milling machine size is about 150mm×100mm×270mm. It is about 1/10 of the general milling machines. To evaluate this machine's performances we first make square parts:5mm×5mm×2mm and we make sure that this square parts accuracy is kept within 0. 01mm. We also make one of typical machine parts : a gear, and a circular pyramidal shape which is called a 2. 5 dimensional sample.

The reaction wheel is a mechanical device for stabilizing the posture of the controlled object by the reaction torque generated when the flywheel is rotated. When applying the reaction wheel to the controlled object, it is necessary to determine the appropriate size of the flywheel, the position to be mounted, the required torque, and so on. However, research on the size and installation position of the flywheel has not been conducted. Therefore, in this study, we construct a model of reaction wheel system on Gazebo which is a 3D dynamic simulator equipped with multiple physical engines. And, we change the various conditions of the flywheel using the model built on Gazebo and consider the influence on posture stability. In addition, by using a robot operating system (ROS) having a coordination function with Gazebo, we control the reaction wheel system on Gazebo.
