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

Abstract

Robots play such remarkable roles in humans' modern lives that performing many tasks without them is<br />impossible. Using robotic systems is gradually increasing the tasks allocated to them and they are becoming<br />more complex and critical. Software reliability is one of the most significant requirements of robots. For<br />enhancing reliability, systems should be inherently designed to be tolerable of soft errors. In this study, via<br />software, a method was proposed to enhance the reliability of the software embedded within robots against<br />soft errors with minimum efficiency overhead. In as much as the research method was based on experiment,<br />a set of programs was used as benchmarks. Indeed, errors were injected at the execution time of programs<br />for evaluating them. The data related to the execution behavior of the programs were accumulated and then<br />were analyzed. Simplescaller simulation software was used for investigating program behavior in the<br />presence of the injected error. [2]
