Chapter synopsis: Mechanical harvesting machines such as canopy and trunk shakers are widely used for yield collection from some crops; however, most fruits and vegetables produced for the fresh market have to be collected manually. This chapter reviews the current state of mechanized collection technology, such as the development of harvest-assist platforms, as well as the possibilities of these machines to incorporate artificial vision systems to perform an in-field pre-grading of the product. The main advantages of each system are discussed and the problems encountered in the field are described. A case study on the use of harvest-assist platforms in citrus orchards is presented describing prototypes that are capable of both inspecting collected fruits and separating them into categories using computer vision.
