The structure and realization of a compact weeding robot in stamping mode for paddy fields

Abstract

A structure of a weeding robot in stamping mode for paddy fields is put forward, which includes an auxiliary supporting device, a weeding device in stamping mode and a striding device. The weeding device in stamping mode realize the evulsing and cutting of weed by walking over and stamping it flat in between the rice shoots with the crawler mobile mechanism. The stamp on weed, which also destroys its habitat, will contribute to the suppression and removal of weed. The turning radius is reduced by the striding over method with tendon-outer-tube transmission system, which greatly enlarges the planting area. The auxiliary supporting device and the striding device, which can avoid slipping and stalling caused by the paddy field pit, cooperate to make the stable movement in the bad condition possible. On the basis of this, the work process of the robot is analyzed, and the strategy of the wedding robot's movement is then proposed. © 2011 Springer-Verlag.
