Question 5: A factory contains an area where all the work is done by robots. The area is fenced and human workers are no supposed to enter while the robots are working. When the fence is opened, it automatically cuts off power to the robots. A worker jumped over the fence to repair a robot that was malfunctioning. Another robot, bringing parts to the malfunctioning robot, pinned the worker against a machine, killing him. Suppose you are a consulting expert hired to investigate this case and write a report. Consider several factors relevant in safety-critical software. What was done right? What was done wrong? What degree of blame should be assigned to the software company that designed the robot system, the company that operates the factory, and the worker? Why? What changes, if any, should the factory operators make to reduce the likelihood of more deaths
