Warehouse management system

A system for managing a multi-level warehouse, the system comprising:

• a. a warehouse path for providing accessibility to wares stored at multiple levels of the warehouse, the warehouse path comprising:
• i. a level path at each level of the warehouse for accessing the wares in the level, each level path at each level comprising:
• 1. a set of guide rails located in aisles of the warehouse, and
• 2. a platform connecting the guide rails, and
• ii. a set of ramps for connecting the level paths;
• b. a plurality of robots to traverse on the warehouse path for accessing the wares, each of the plurality of robots having a handling means for handling the wares and a moving means for moving a robot along the warehouse path, wherein the moving means comprises;
• i. a first moving means for allowing movement on the platform of the warehouse path that is a plain surface;
• ii. a second moving means for allowing movement along the set of guide rails;
• iii. wherein each of plurality of the robots is configured to shift between the first moving means and the second moving means based on one of the platform and the set of guiderails to be traversed;
• c. a control unit for managing activities of the plurality of robots, the control unit having a route calculating module for calculating a route to be traversed by the robots on the ware-house path based on real-time status information of the warehouse, wherein the real-time status information relates to the wares, the robots, the status of the one or more lifts, the warehouse path, and inputs provided by a user;
• d. a wireless communication network for enabling transfer of warehouse information between the plurality of robots and the control unit for operation of the robots, the warehouse information comprising the real-time status information;
• and
• e. one or more lifts wherein each of the one or more lifts is connected to the control unit through a lift communication module via the wireless communication network, wherein the lift communication module is configured to share status of the lift with the control unit to compute the route.
