Abstract: A real-time operating system (RTOS) is a software which ensures that time critical events are processed as efficiently as possible. In this paper, an attempt has been taken to implement a real time operating system, named Preemptive Real Time Operating System (PRTOS), in which all of the important tasks regarding to a real time application have been considered. In this PRTOS, strictly preemptive scheduling algorithm has been used. This Scheduling policy makes sure that important tasks are handled first and the less important later. In this paper we are using free RTOS . Free RTOS” is a small but powerful real-time kernel and it is used in many commercial applications. In this paper our intention is to design and construct a self navigating robot which works on Preemptive priority algorithm. This Free RTOS supports Tasking, Semaphores, Timer Management, Message Queues, Single Step Debugging support, and with Task synchronization. In this paper Robot is operated with Global Positioning system which allows the robot to aware of its position on the earth. Here PRTOS concept is implemented to control the different operational tasks .Hence This robots found some Real time applications like war fields ,mines and complex locations where the humans unable to reach.
