In the whole process of parcel sorting, the role of manpower is not irreplaceable. For example, in the parcel infeed process, the efficiency and accuracy of manual infeed depend on the proficiency of operators, which greatly limits the sorting efficiency of the entire parcel sorting system. To solve this problem, Wayzim developed many solutions such as semi-automated infeed, parallel automated infeed, and automated robotic infeed by combining with its intelligent vision system. These solutions upgrade the automation of the infeed process and minimize the uncertainty of manual operations.
