1. A system comprising:

  • a robotic manipulator;

    one or more optical sensors;

    at least one processor; and

    data storage comprising instructions executable by the at least one processor to cause the system to perform functions comprising;

    based on data indicating that a machine-readable code is included on at least one face of at least one physical object, causing the robotic manipulator to grasp the at least one physical object at one or more locations on the at least one physical object different from the at least one face and move the at least one physical object through a designated area in space of a physical environment of the system such that the at least one face of the at least one physical object moves within a particular field of view of the one or more optical sensors,causing the one or more optical sensors to (i) determine a location of the machine-readable code on the at least one physical object as the at least one physical object is moved through the designated area in space and (ii) based on the determined location, scan the machine-readable code as the at least one physical object is moved through the designated area in space so as to determine information associated with the at least one physical object encoded in the machine-readable code, andbased on the information associated with the at least one physical object, determining a respective location in the physical environment at which to cause the robotic manipulator to place the at least one physical object.
