Proposing an Efficient Software-Based Method for Enhancing the Reliability of Critical Application Robot

Robots play such remarkable roles in humans’ modern lives that performing many tasks without them is impossible. Using robotic systems is gradually increasing the tasks allocated to them and they are becoming more complex and critical. Software reliability is one of the most significant requirements of robots. For enhancing reliability, systems should be inherently designed to be tolerable of soft errors. In this study, via software, a method was proposed to enhance the reliability of the software embedded within robots against soft errors with minimum efficiency overhead. In as much as the research method was based on experiment, a set of programs was used as benchmarks. Indeed, errors were injected at the execution time of programs for evaluating them. The data related to the execution behavior of the programs were accumulated and then were analyzed. Simplescaller simulation software was used for investigating program behavior in the presence of the injected error.
