Abstract: The present invention provides a device and a method for picking and collecting Brasenia schreberi based on a machine vision. The device for picking and collecting Brasenia schreberi includes a supporting mechanical arm, a collection device, two working mechanical arms, a picking manipulator, a grasping manipulator, a control box, and a visual system. The supporting mechanical arm is fixed on a front end of a boat; the two working mechanical arms are fixed on a front end of the supporting mechanical arm; the picking manipulator and the grasping manipulator are mounted on tail ends of the two working mechanical arms, respectively; and the collection device is fixed on the boat; the visual system determines a location of the Brasenia schreberi and sends the location to the control box; the control box controls the two working mechanical arms, the grasping manipulator, and the picking manipulator to complete the grasping and picking of the Brasenia schreberi; and then the collection device collects the Brasenia schreberi.

Abstract: The present invention provides a ground-contour-following autonomous obstacle avoidance mower for hillside orchards and a control method thereof. Through cooperation of a push rod motor and a rotating pair, multi-angle cutting is achieved, and energy consumption needed by mowing operation is reduced. A connecting rod is arranged and forms a flexible mechanism together with an upper base bearing, a lower base bearing and a base-connecting unthreaded shaft. The flexible mechanism interacts with the push rod motor to achieve ground contour following operation, so that the mower as a whole can conduct ground-contour-following mowing operation on a complex orchard terrain, with a better cutting effect than that of a traditional mower. The use of a right-angle bypassing obstacle avoidance mode realizes precise obstacle avoidance of the mower, and achieves the operation purpose of not excessively relying on operators.
