RTno is communicating library and framework which allows you to make your embedded device capable of communicating with RT-middleware world. RT-middleware is a platform software to realize Robotic system. In RTM, robots are developed by constructing robotics technologies\' elements (components) named RT-component. Therefore, the RTno helps you to create your own RT-component with your mbed and arduino.
