An effector coupled to an automated harvesting apparatus, the effector comprising a sensor unit configured to obtain fruit cluster related data relating; a closed kinematic chain mechanism configured: to expand from a closed configuration to an expanded configuration; close from the expanded configuration to the closed configuration; harvesting shears configured to cut the fruit stem, said harvesting shears are coupled to the kinematical closed chain mechanism; a catch mechanism configured to catch the fruit stem after the fruit stem is cut by the harvesting shears; and, a processor configured to operate the effector to cut the fruit stem.
