A mushroom trimming and sorting system comprises a stem trimming device, a positioning system, an imager set, and a controller operable to control the positioning system to move a single mushroom into view of the imager set, to generate an image set of the mushroom, and to process the image set (and optionally other sensor data) to determine mushroom properties of the mushroom. The positioning system may include a SCARA robot with suction-type end effector and single-mushroom elevator with gripping mandibles. The processing may employ a trained machine-learning model. The mushroom properties may include a length of an end portion of the stem bearing soil, and a sorting category of the mushroom based on parameters of the cap including degree of gill opening. The end portion is them trimmed to eliminate soil and other defects, and sorting the mushroom into one of a plurality of receptacles.

An automated mushroom harvesting system for mounting to a vertical mushroom rack comprises a robot having a frame mounted to a vertical carriage assembly. A SCARA arm is slidably mounted to the vertical carriage assembly by a vertical stage, operable to move the SCARA arm along a vertical mast. The SCARA arm moves the end effector in a horizontal plane for harvesting mushrooms, above the surface of the mushroom bed and into and out of the confines of the mushroom rack, and the vertical stage moves the SCARA arm in a vertical direction so as to access the mushrooms in a bed and to access mushroom beds on different levels of the vertical mushroom rack. An end effector having a helically reinforced neck and a graduated elasticity modulus, with a lower elasticity modulus in the neck and a higher elasticity in the cup, is also provided.
