1. A computer-implemented method, comprising: identifying, by one or more processors, an approximation of a space within an environment, wherein identifying the approximation comprises: detecting, based on visual data sensed by one or more vision sensors, an operator gesture associated with user identification of the space within the environment, and temporally synchronizing the operator gesture with audio data sensed by one or more audio sensors, wherein the operator gesture is detected in the visual data based at least in part by identifying one or more frames of the visual data that correspond temporally with one or more utterances captured in the audio data that are associated with user identification of the space; extrapolating, by one or more of the processors, the space within the environment based on the approximation and one or more attributes of the environment; identifying, by one or more of the processors, a plurality of objects that are co-present within the space, wherein the plurality of objects are to be manipulated by a robot; and operating, by one or more of the processors, the robot to manipulate the identified plurality of objects.
