Abstract: A modular multi-mode conveyor system comprising: at least one linear drive track section configured such that moving elements are independently controlled and moved along the track section; and at least one mechanical drive track section having the same configuration as the linear drive track section but wherein the linear drive is replaced with a scroll cam drive system and moving elements are controlled and moved along the track section by the scroll cam drive system. The scroll cam conveyor system comprising: a scroll cam including: a cylindrical cam; a plurality of cam grooves formed on the cylindrical cam; a drive system for rotating the scroll cam; and a moving element comprising: a plurality of cam followers, wherein the plurality of cam grooves are configured to contact with respective ones of the plurality of cam followers to move the moving element.
