Center node: "robot hazards from safety to security"
  Abstract: Robotics landscape is experiencing big changes. Robots are spreading and will soon be everywhere. Systems traditionally employed in industry are being replaced by collaborative robots, while more and more professional and consumer robots are introduced in people's daily activities. Robots are increasingly intertwined with other facets of IT and envisioned to get much more autonomy, interacting physically with humans. We claim that, following Personal Computers (PCs) and smartphones, robots are the next technological revolution and yet, robot security is being ignored by manufacturers. The present paper aims to alert about the need of dealing not only with safety but with robot security from the very beginning of the forthcoming technological era. We provide herein a document that reviews robot hazards and analyzes the consequences of not facing these issues. We advocate strongly for a security-first approach as a must to be implemented now.
