A development tool for embedded system using OpenRTM-aist is shown. RT middleware is an standard platform software in which robotic elemental devices such as actuators, sensors, and so on, are treated as 'Components' and those components allows users to re-use them. We developed "RTno" to make it easier to make original embedded system like controllers, sensor network, etc. In this paper, the first version of the RTno is shown in detail.
