RT Middleware is useful as a framework for a robot’s productivity drive. However, in advancing spread and promotion, subjects occur. They are the difficulty of introduction of technological know-hows of RT Middleware, and the little of those who can develop corresponding software. Then, we thought that we would enable it to treat RT Middleware on the Android framework who has spread widely all over the world quickly. Therefore, we developed “RTM on Android”, a RT-Middleware for the Android platform. By using our “RTM on Android”, you are able to develop application-RT-Components for Android easily, now.
