1. A robotic harvester comprising a mobile platform with a power source, a programmable multi-axis robot arm connected to the robotic harvester, a master controller connected to the robotic arm, a stereovision camera mounted on the mobile platform, the master controller being a computer having software programmed to control the robot arm to relate the stereovision camera to the robot arm; a hood that covers the stereovision camera and its field of view; a gripper attached to the robot arm and controllable by the computer, wherein the stereovision camera, with a single measurement, locates and identifies an object in geometric 3D coordinates, the computer directing the robot arm to the object using the geometric coordinates and the gripper grasping the object and removing the object; wherein the gripper has a plurality of spaced-apart removable fingers, each finger having a pivotable finger tip, the finger tips being rotatable toward each other; the object being grasped between the fingers of the gripper, the object having a stem attached thereto, the stem of the object being disposed and held between two of the fingers wherein stem tension is measurable and wherein movement of the robot arm is able to separate the stem from the object; and wherein at least one retaining wall is formed on the fingers of the gripper.
