ABSTRACT:
A method of transporting items includes receiving a group of one or more items in a singulation device, implementing a singulation routine, measuring a speed of a first portion of the group, measuring a speed of a second portion of the group, and comparing the speed of the first portion with the speed of the second portion. The method may further include continuing the singulation routine where the speed of the first portion is not equal to the speed of the second portion, and terminating the singulation routine where the speed of the first portion is equal to the speed of the second portion. The method may also include transporting a lead item away from the singulation device. The singulation device may include opposing transport elements.
