Abstract
In order to develop a safe robot, it must be protected from a harm by a robot. Determining the specifications of the robot to identify hazards, we must conduct a risk assessment based on the specifications. In this report, a case study of developing a vending robot, we performed a determination of the specifications and a risk assessment. As a result, we can analyze that much of the harm is the crash between human and robot. We proposed safety measures to reduce this risk and investigated the crash safety testing and running durability test in order to verify measures of the effect.
