Robot mechanical picker system and method

Embodiments of the invention comprise a system and method that enable robotic harvesting of agricultural crops. One approach for automating the harvesting of fresh fruits and vegetables is to use a robot comprising a machine-vision system containing rugged solid-state digital cameras to identify and locate the fruit on each tree, coupled with a picking system to perform the picking. In one embodiment of the invention a robot moves through a field first to “map” the field to determine plant locations, the number and size of fruit on the plants and the approximate positions of the fruit on each plant. A robot employed in this embodiment may comprise a GPS sensor to simplify the mapping process. At least one camera on at least one arm of a robot may be mounted in appropriately shaped protective enclosure so that a camera can be physically moved into the canopy of the plant if necessary to map fruit locations from inside the canopy. Once the map of the fruit is complete for a field, the robot can plan and implement an efficient picking plan for itself or another robot. In one embodiment of the invention, a scout robot or harvest robot determines a picking plan in advance of picking a tree. This may be done if the map is finished hours, days or weeks before a robot is scheduled to harvest, or if the picking plan algorithm selected requires significant computational time and cannot be implemented in “real time” by the harvesting robot as it is picking the field. If the picking algorithm selected is less computationally intense, the harvester may calculate the plan as it is harvesting. The system harvests according to the selected picking plan. The picking plan may be generated in the scout robot, harvest robot or on a server. Each of the elements in the system may be configured to communicate with each other using wireless communications technologies.

Self contained transport for crop harvesting header

A transport system for a crop header includes a first and a second wheel arrangement on the header frame adjacent a respective ends for acting as a stabilizer when the header is in the operating position and movable to a transport position for transporting the header when removed from the vehicle in a transport direction generally longitudinal of the header frame and at a right angle to the working direction with each being mounted on the header frame for rotation of a rolling direction of the first wheel arrangement between the working position and the transport position, in which the rolling direction is along the transport direction. Each of the wheel arrangements includes two parallel wheels coupled together. The wheel arrangement at the rear end includes a second wheel which is mounted on a swing arm so as to be moved to a position adjacent the cutter bar so that the header is stably supported on the first wheel arrangement, the first wheel of the second wheel arrangement and the second wheel of the second wheel arrangement. The first and second wheels of the second wheel arrangement include coupling members for connection together to operate as a common wheel arrangement in the operating position. The swing arm includes a tower which attaches to the cutter bar and can fold down on to the swing arm in the field position.

Crop stripper for the crop transport draper of a header

A draper header for a combine harvester includes two side drapers each running from an outer end guide roller at a first end of the header to an inner end guide roller adjacent the discharge location of the header and a central feed draper located at the discharge location and including a front guide roller just behind the cutter bar and running to a rear guide roller in front of the feeder house of the combine harvester. Each inner end guide roller is associated with a respective discharge roller immediately adjacent and parallel to it with a stripper blade in contact with the peripheral surface of the discharge roller so as to strip the crop from the peripheral surface along the full length of the roller. Each stripper blade is inclined downwardly and inwardly to a bottom edge closely adjacent the upper run of the feed draper. The stripper roller or in another arrangement the draper itself has rows of projections across the surface which pass through corresponding shaped recesses in the edge of the stripper blade so that the crop material is discharged onto the blade while the projections are shaped to prevent the crop from being driven into the recesses. An auger is located between the discharge rollers with a front edge of the flight forward of the rear end of the discharge rollers to feed the material inwardly and underneath the auger to the inlet of the feeder house.
