Behavior identification device, air conditioner, and robot control device

A robot control device comprising:

• a behavior identification device that identifies a behavior of a target using a sensor value measured by a sensor for the behavior of the target, the behavior identification device including:
• processing circuitry configured to obtain the sensor value and calculate a sensor value distribution that is a distribution of the sensor value measured within a predetermined time,
• a component memory that stores therein a set of basic distributions that are basic components constituting the sensor value distribution, and
• a component ratio memory, wherein
• the processing circuitry is configured to calculate a first component ratio that is a ratio of each of the basic distributions included in the sensor value distribution,
• the component ratio memory stores therein a second component ratio that is the ratio determined in association with a behavior to be identified,
• the processing circuitry is configured to compare the first component ratio to the second component ratio to identify the behavior,
• the basic distribution is calculated as a sensor value distribution that is a base when each sensor value distribution is assumed to be a vector based on a set of the sensor value distributions obtained in advance for each of a plurality of types of the behavior, and
• the robot control device identifies a safe behavior that is set in advance as the behavior of the target, a dangerous behavior that is set in advance, and a deviant behavior that is not set in advance to control an operation of a robot based on an identification result.
