摘要： A deformeter for testing the firmness of fruit as an indication of its maturity includes a support for an individual fruit effective to convey the fruit to a testing location, at which sensors are urged to contact the fruit surface lightly, preferably on a diameter, to establish a datum position. The sensors are then urged to contact the fruit with a predetermined, deforming pressure. At least one more sensor moves correspondingly into the fruit to establish an indented position. The two sensor positions are electrically noted and are subtracted to afford an indented distance from datum position indicative of firmness and so maturity. A modification uses a pair of first sensors arranged on opposite sides of the fruit in a trailing position, the pairs operating in sequence and being arranged with all sensors substantially in the same, vertically adjustable plane.BRIEF SUMMARY OF THE INVENTIONFruit advancing intermittently or steadily in a path to a station is lightly contacted at the station to establish a datum location of the fruit surface and then is more heavily contacted at the station with a predetermined force to produce an indentation, the amount of which is measured from the datum location and is indicative of firmness and maturity.

摘要： A robotic cultivator is provided for automatically positioning cultivation tools relative to a centerline of a plant row. The cultivator comprises a video camera for gathering visual information about plants in a plant row. A frame grabber is then utilized to generate a digitized image of the visual information. A computer then manipulates the visual information to determine a centerline of the plant row. Finally, a positioning device moves the cultivation tools based upon the current position of the tools with respect to the centerline.
