Robots make the best and the worst security guards. On the one hand, they’re efficient, precise, and unswayed by emotions. On the other hand, they’re also cold, impersonal, and unyielding. They are best used for security-related tasks that require more attention to detail but not so much human interaction. That’s what Cobalt Robotics is attempting with its autonomous mobile robot that can navigate around the area, recognize people, read IDs, and report any suspicious activities, potential security issues, and possible hazards. All without looking like a Terminator set to kill.
