Method for tracking stock level within a store

A method for tracking stock level within a store comprises:

• at a robotic system, over a first period of time:
• navigating along a first inventory structure in the store;
• broadcasting radio frequency interrogation signals according to a first set of wireless scan parameters;
• recording a first set of wireless identification signals returned by radio frequency identification tags coupled to product units arranged on the first inventory structure;
• and
• recording a set of optical images of the first inventory structure;
• generating a first list of product units arranged on the first inventory structure based on the first set of wireless identification signals;
• identifying a second set of product units arranged on the first inventory structure in the set of optical images;
• detecting a first product quantity difference between the first list of product units and a first target stock list assigned to the first inventory structure by a planogram of the store;
• detecting a first product location difference between locations of product units, in the second set of product units identified in the set of optical images, and product locations assigned to the first inventory structure by the planogram;
• and
• in response to the first product quantity difference and the first product location difference, generating a stock correction prompt for the first inventory structure.

• in response to a difference between the list of product units and a first target stock list assigned to the first inventory structure by a planogram of the store, defining a second set of wireless scan parameters differing from the first set of wireless scan parameters;
• at the robotic system, over a second period of time succeeding the first period of time:
• navigating along the first inventory structure;
• broadcasting radio frequency interrogation signals according to the second set of wireless scan parameters;
• and
• recording a second set of wireless identification signals returned by radio frequency identification tags coupled to product units arranged on the first inventory structure;
• generating a second list of product units arranged on the first inventory structure based on the second set of wireless identification signals;
• generating a digital report of products stocked on the first inventory structure based on a combination of the first list of product units and the second list of product units.
