Applying software reuse to many Embedded Real-Time (ERT) systems poses significant challenges to industrial software processes due to the resource-constrained and real-time requirements of the systems. Autonomous Mobile Robot (AMR) system is a class of ERT systems, hence, inherits the challenge of applying software reuse in general ERT systems. Furthermore, software reuse in AMR systems is challenged by the diversities in terms of robot physical size and shape, environmental interaction and implementation platform. Thus, it is envisioned that component-based softwareengineering will be the suitable way to promote software reuse in AMR systems with consideration to general requirements to be self-contained, platform-independent and real-time predictable. A framework for component-oriented programming for AMR software development using PECOS component model is proposed in this paper. The main features of this framework are: (1) use graphical representation for components definition and composition;(2) target C language for optimal code generation with resource-constrained micro-controller;and (3) minimal requirement for run-time support. Real-time implementation indicates that, the PECOS component model together with the proposed framework is suitable for resource constrained embedded AMR systemssoftware development.

The explosive and unprecedented growth with new innovation in wireless technology has opened up a new window for life-saving telemedicine services. After every couple of weeks a competitive solution is provided with the help of state-of-the-art technology to serve human beings every where on their move. By adopting advantages of telemedication the life in remote areas is facilitated. In this paper the working design of a quality ensuing wireless telemedicine system is proposed. The system activates real-time interactive medical data in a wireless environment. It handles vital sign telemonitoring technique that acquires, stores, and forward readings of electrocardiographs (ECG) and temperature over the wireless LAN. The browser based application is customized for 802.11b. The paper describes the quality ensuing design and implementation of portable medical unit that allows monitoring any where and that can be uses for various monitoring scenarios of homecare-units, hospital, the emergency and disaster relief centers. Existing telemedicine systems use traditional hard-wired, bandwidth-reserved mechanisms or road-mobile medical services for a real-time monitoring of patient. The preliminary results of telemedication determine that this level of service is not beneficial in monitoring patient with the help of stationary system or mobile-medication. Moreover, switching via GSM may guarantee a territory in range but low bandwidth, small data rates and system expense become an obstacle. The wireless broadband services guarantees full coverage and system expenses are for session based only. This research paper demonstrates for a practicable telemedication system with potential security features available with IEEE 802.11b standard.
