  • Publication number: 20210267125
    Abstract: A three-dimensional stereo vision camera communicates the location of a targeted fruit (preferably an apple) to a controller. The controller directs a vacuum selection tube to the location of the targeted apple. The selection tube has a gripping orifice that has a smaller diameter than the apple so that the vacuum suction from the selection tube grips the apple. The selected fruit is then rotated and pulled away from the tree canopy by the selection tube until the apple detaches from the canopy. The detached apple is then gently placed in a collection bin for later sorting and processing.
