Dynamically configurable articulating surfaces for mobile carrier units

An item sorting system comprising:

• an induction portion at which an object for sortation is input at the item sorting system;
• a plurality of containers;
• and
• a mobile carrier unit configured to transport the object from the induction portion to a designated container of the plurality of containers, the mobile carrier unit comprising:
• a plurality of tiles that form a surface on which to load the object, the plurality of tiles comprising:
• a first row of tiles configured to articulate from a first position to a second position, the first row of tiles disposed along a first edge of the object;
• a second row of tiles configured to articulate from the first position to the second position, the second row of tiles disposed along a second edge of the object;
• a first column of tiles configured to articulate from a third position to a fourth position, the first column of tiles disposed along a third edge of the object;
• and
• a second column of tiles configured to articulate from the third position to the fourth position, the second column of tiles disposed along a fourth edge of the object;
• a first actuator configured to actuate the first row of tiles;
• a second actuator configured to actuate the second row of tiles;
• a third actuator configured to actuate the first column of tiles;
• and
• a fourth actuator configured to actuate the second column of tiles;
• wherein the first position and the third positions are inclined positions, and the second position and the fourth position are declined positions.
