Methods, apparatus, and systems for managing objects

An apparatus, comprising:

• an entry gate;
• a sorting scale coupled to the entry gate;
• an exit gate coupled to the sorting scale;
• a sorting gate, wherein the sorting gate includes two substantially parallel components;
• a plurality of gates coupled to the sorting gate;
• and
• a processor and a memory storing executable instructions that, in response to execution by the processor, cause the apparatus to:
• open the entry gate to enable a first object to enter the sorting scale through the entry gate;
• obtain a first weight of the first object using the sorting scale;
• close the entry gate upon determining the first weight of the first object is higher than a predetermined weight;
• move the two substantially parallel components of the sorting gate based on the first weight of the first object to form a passageway between the exit gate and one of the plurality of gates, wherein the two substantially parallel components of the sorting gate are substantially parallel before and after the moving;
• thereafter,
• open the exit gate to enable the first object to pass through the passageway and reach the one of the plurality of gates;
• obtain a second weight of the first object using the sorting scale;
• close the exit gate upon determining the second weight of the first object is lower than the predetermined weight;
• determine that the exit gate has been opened for a predetermined period of time;
• and in response,
• open the entry gate while the exit gate is open to enable a second object to enter the sorting scale through the entry gate to facilitate the first object to pass through the exit gate.
