ABSTRACT:
Apparatus for harvesting delicate produce--but particularly mushrooms--includes a picking head which is controlled to be positioned over an item of produce to be harvested, by a camera which scans a tray of said items and a control unit operating on a camera output to determine the co-ordinates of those items found to be suitable for picking, for example from the size of those items. The picking head includes a bellows-like produce gripper through which air is drawn to hold an item of produce securely but gently against an engagement face at the free end of the gripper. Once the item has been securely held, it is pulled free by twisting and lifting action, imparted to the picking head. The stalk is then cut away by a cutter, and the item is deposited in a box carried on a separate conveyer.
