Safety system for integrated human/robotic environments

A safety system, comprising:

• one or more sensors;
• a computing device, the computing device comprising:
• one or more processors;
• and
• data storage including at least computer-executable instructions stored thereon that, when executed by the one or more processors, cause the computing device to perform functions comprising:
• receiving, at the one or more sensors, a signal that is emitted by a device worn by an actor present within an environment;
• determining a particular safety classification, for a robot in the environment, based on the signal received at the one or more sensors, wherein determining the particular safety classification comprises:
• determining a first safety classification if the signal has one or more predetermined first characteristics, and
• determining a second safety classification if the signal has one or more predetermined second characteristics, wherein the second safety classification is more restrictive than the first safety classification;
• and
• after determining the particular safety classification based on the signal, causing the robot to operate according to a safety rule that corresponds to the particular safety classification.
