ABSTRACT
This chapter presents various important aspects of software, robot, and transportation system safety. Software safety may be grouped under three classifications: Safety software, Nonsafety software and Safety-critical software. Software sneak circuit analysis is a method that is concerned with identifying software logic that leads to the occurrence of undesirable outputs. Nowadays, robots are being used in many diverse areas and applications, and their safety-related problems have significantly increased over the years. Generally, a well-designed robot incorporates, to the greatest extent possible, safety-related features that take into consideration all modes of robot operation. The flashing light method calls for the installation of a flashing light on the robot itself or at the perimeter of the work area of the robot. Railroad tank cars are used for transporting various types of liquids and gases from one point to another, and their contents are flammable and corrosive or pose other various hazards if released accidently.
