1. A method of operating a mobile robot to conduct a multi-object search task, the mobile robot having at least one processor executing computer readable instructions stored in at least one non-transitory computer readable storage medium to perform operations comprising:
representing a multi-object search task in an Object-Oriented Partially Observable Markov Decision Process model having at least one belief pertaining to a state and at least one observation space within an environment of the robot, wherein the state is represented in terms of classes and objects and each object has at least one attribute and a semantic label;
receiving, at the mobile robot from a user, a language command identifying at least one target object and at least one location corresponding to the target object;
updating the at least one belief, associated with the at least one target object, based on the language command;
driving the mobile robot to the at least one observation space identified in the updated belief;
searching, using at least one sensor on the mobile robot while traversing the at least one observation space identified in the updated belief, for the at least one target object; and
notifying the user upon finding the at least one target object.
