Transfer systems and methods

A transfer system comprising:

• a first belt assembly comprising:
• a first strip belt;
• a first active pulley, wherein the first active pulley is coupled to the first strip belt;
• a first driver, wherein the first driver is configured to drive the first active pulley in
• a first direction at a first power level, thereby driving the first strip belt;
• a second belt assembly comprising:
• a second strip belt;
• a second active pulley, wherein the second active pulley is coupled to the second strip belt;
• a second driver, wherein the second driver is configured to drive the second active pulley in a second direction at a second power level, thereby driving the second strip belt;
• a plurality of balls comprising a shared diameter and disposed on or within a shared plane, wherein at least one of the plurality of balls is operably engaged with the first strip belt and configured to rotate in the first direction when the first driver drives the first active pulley, wherein at least one of the plurality of balls is operably engaged with the second strip belt and configured to rotate in the second direction when the second driver drives the second active pulley;
• and
• a bed, wherein the plurality of balls are disposed on or within the bed, wherein the bed comprises one or more bed idler pulley disposed on or in one or more sides of the bed.
