Title: Fruit Tree Pruner and Harvesting MachinePublication number: US2012096823 (A1)Publication date: April 26, 2012Inventor(s): Moore Francis Wilson (USA)

Abstract: This invention is a dual function tree pruner and fruit harvester that use the same equipment for pruning and for harvesting. The Fruit Tree Pruner and Harvesting Machine features: a self-propelled-vehicle (SPV), computer controlled robotic arms, a digital imaging system (DIS), a radar ranger system (RRS), global positioning satellite (GPS), guidance system, geographic information system (GIS), a power pruner or power stem cutter as appropriate, a fruit vacuum system, a fruit catcher, a fruit handling system, and a fruit bin loader. The operation is automated and the operator monitors and sets parameters. The Fruit Tree Pruner and Harvesting Machine can prune a tree to a predetermined profile. The tree can be shaped per the orchard’s requirements. The invention utilizes data obtained during the pruning process to find the fruit, and to remove the fruit while maintaining the fruit quality suitable for the fresh market.

Title: Machine vision based weeding robot system and method thereofPublication number: CN101990796 (A)Publication date: March 30, 2011Applicant(s): University China Agricultural

The invention can realize rapid and accurate weeding operation on crop in the field.

Title: Tree climbing type carya cathayensis picking robotPublication number: CN102405729 (A)Publication date: April 11, 2012Applicant(s): University Zhejiang Technology

Abstract: A tree climbing type carya cathayensis picking robot comprises a tree climbing mechanism, a mechanical arm and a tail-end execution device. The mechanism arm is installed on the tree climbing mechanism, and the tail-end execution device is installed on the upper end of the mechanism arm. The mechanical arm comprises a rotary mechanism. The rotary mechanism comprises a rotary motor, a rotary motor frame, a support plate and a bearing plate. The bearing plate is fixed at the upper side of the support plate through four support columns, and the rotary motor is fixed on the rotary motor frame, the rotary motor frame is fixed on the support plate. The output shaft of the rotary motor is connected with a connection shaft, and the connection shaft passes through the bearing plate. A horizontal bearing and a horizontal bracket are fixed on the bearing plate; and the connection shaft, the horizontal bearing and the horizontal bracket are fixedly connected. The horizontal bracket is connected with a classis, a left row and a right row of vertical bearings are fixed on the classis; a left main arm is connected with the vertical bearings through a basic shaft, and a right support arm is connected with the vertical bearings through two cut-off semi-shafts; and the main arm is connected with the support arm through pins. The invention has good operability, low cost and good safety.

Title: Horizontal swing type inter-plant weeding devicePublication number: CN102138377 (A)Publication date: August 3, 2011Applicant(s): University South China Agricult

Abstract: The invention discloses a horizontal swing type inter-plant weeding device, which comprises a car body, wherein the car body comprises a main frame and a depth wheel; the horizontal swing type plant weeding device also comprises a horizontal swing weeding structure, a weeding component, an inter-row weeding structure and a vision and control system which are arranged on the main frame, wherein the horizontal swing weeding structure leads the weeding component to enter an inter-plant area for weeding through horizontal swing movement; the inter-row weeding structure enters the soil to weed through a shovel with double swings; and the vision and control system identifies crops, determines a plant protection area and an inter-plant weeding area and controls the horizontal swing weeding structure and the inter-row weeding structure to weed in the inter-plant weeding area. In the invention, the requirements of the inter-plant weeding device on the crop row tracking accuracy of a towing tractor can be reduced; the dependence of the inter-plant weeding device on the high crop row tracking accuracy of a weeding robot or the towing tractor is reduced; and the width of the inter-plant weeding shovel with the double swings can be selected according to row space so as to adapt to the weeding in inter-plant areas of grown crops of different row spaces.

Title: Autonomous operation forestry robot platformPublication number: CN102135766 (A)Publication date: July 27, 2011Applicant(s): University Beijing Forestry

Abstract: The invention discloses an autonomous operation forestry robot platform, which comprises a robot body and a control system, wherein the robot body has a four-wheel drive structure and comprises a vehicle chassis, a vehicle roof platform, a vehicle frame and the like; and the control system of a robot can finish complex control and data processing algorithms and is provided with various sensors such as a navigation positioning sensor, a laser measurement sensor, a binocular vision sensor and the like so as to perform information detection and intelligent navigation on an autonomous forestry robot operation environment.
