Abstract
A ground-contour-following autonomous obstacle avoidance mower for hillside orchards and a control method thereof are provided to achieve multi-angle cutting and low energy consumption in mowing operation through cooperation of a push rod motor and a connecting-rod rotating pair. 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.
