A localization system comprises: a device; a master unit which wirelessly transmits a first localization signal; a plurality of lateration units distributed about the area within which the device is being localized, wherein each lateration unit of the plurality independently starts its own timer upon its receipt of the first localization signal; and a localization unit. The device receives the first localization signal and responsively wirelessly transmits a second localization signal. Each of the lateration units: independently receives the second localization signal; stops its respective timer responsive to receipt of the second localization signal; and wirelessly transmits a timer count signal to a localization unit. The timer count signal identifies the transmitting lateration unit and a count of its respective timer. The localization unit utilizes the plurality of timer along with respective distances between the master unit and the lateration units to localize the first device via time-of-flight lateration.

The processor of the mobile object control system calculates the target speed of the mobile object on the basis of the first operation amount for each individual operation terminal, calculates the target turning angular speed of the mobile object on the basis of the second operation amount for each individual operation terminal, combines the target speed calculated for each individual operation terminal at the first ratio to calculate the final target speed, combines the target turning angular speed calculated for each individual operation terminal at a second ratio different from the first ratio to calculate the final target turning angular speed, and controls one or a plurality of actuators related to the traveling of the mobile object on the basis of the final target speed and the final target turning angular speed.

Provided is a robot device and method of controlling same, wherein the robot device includes: at least one sensor; at least one memory configured to store at least one instruction; and at least one processor configured to execute the at least one instruction to: based on the robot device being positioned at a first position, control the robot device in a first mode corresponding to the first position, identify, based on sensing data obtained by the at least one sensor, a first event of picking up the robot device by a user and a second event of placing the robot device, and based on an identification that a position of the robot device is changed from the first position to a second position based on new sensing data obtained by the at least one sensor after the first event and the second event sequentially occur, control the robot device in a second mode corresponding to the second position.
