Claim 10:
11. A method for safely operating robots in an environment, the method comprising:
receiving sensed data from a set of heterogeneous sensors in the environment related to humans and robots operating within the environment, at least one of the heterogeneous input sensors positioned off-board the robots;
slowing or stopping the robots, by one or more safety systems (i) being respectively executed by the robots and (ii) including input one or more sensors that are different from the set of heterogeneous input sensors, in the event of the robot detecting a potential interaction with another robot or human;
determining a probability that a safety system will activate as a function of the received sensed data from at least one of the heterogeneous sensors;
pre-processing, using a plurality of data pre-processor sub-modules with at least two being different from one another, the sensed data to generate preprocessed sensed data;
extracting features, using a plurality of feature extraction sub-modules with at least two being different from one another, from the preprocessed sensed data so as to generate extracted feature data;
classifying, using a plurality of classifier sub-modules with at least two being different from one another, extracted feature data to generate classified risk predictions indicative of a safety system activation; and
generating, using an ensemble classifier, an overall safety prediction that defines a probability of activation of a safety system in the area being monitored by the input sensors based on the classified risk predictions, the overall safety prediction being generated by executing a supervised learning algorithm; and
generating an output signal to cause at least one of a notification to alert a human or a control command to alter planned movement of a robot to avoid activation of the safety system of the robot that causes the robot to slow down.
