It adopts a crawler-type walking device, which is suitable for harvesting forest fruits in hilly areas, especially for soil work surfaces with large slopes in mountain roads. Flexible maneuverability, high work efficiency, small working space requirements, and high harvesting efficiency. But its occupied area is bigger, is not suitable for the plucking of dried fruit orchards such as hillside.

There is a domestic patent disclosure of "a tree-climbing type pecan picking robot", the patent number of which is 201110377079.6. This hickory picking robot includes a tree climbing mechanism, a mechanical arm and an end effector. After the mechanical arm is positioned so that it is within a certain distance in front of the picked fruit, the action of the mechanical arm is stopped. Start the executive motor, the motor drives the crank to rotate, and the scissors are closed through the crank slider mechanism to cut off the hickory. The hickory nuts fall into the collection box under the action of their own weight. This picking robot has complicated structure, low efficiency and is not suitable for large-scale walnut grove picking.
