REDEEMING OF PROCESSOR FOR CYBER PHYSICAL SYSTEMS USING RTOS

V. Shanmuga Priya, T.Selvasankari

Abstract: Cyber Physical Systems (CPS) are designed to make a software application directly interact with the events in the physical world. These systems will have a constant sensor sampling rate and processor response time. When they are deployed to processors that are shared amongst control and non-control tasks it will potentially increases CPU usage, such as cache, interrupts and task management through schedulers, which results in interference between tasks. This response time jitter reduces system stability. Hence Experiments are done in control and computing communities with the scope of maximizing CPU utilization and maintaining System stability. In this paper we develop a Microcontroller Based Multifunctional Mobile Robot with real time movement is demonstrated which replaces huge man power for various applications. It is designed for Military purpose and functions at critical time. Navigation of the Robot is done through Zigbee technology and it uses RF to communicate with the Tankers. A Wireless AV receiver at the Base station displays the images captured by the Camera. To make the Robot highly secured it is coupled with a Laser gun and it interacts with the physical world through sensors such as Obstacle sensor and Vibration sensor. All these functions of the Robot are completed within their deadline through Salvo Rtos.
