Abstract: In order to solve the underlying problems of intensive manual labour, low working efficiency and backward traditional machinery in harvesting and husking process of chestnut production, a chestnut autonomic harvesting and husking machine with Raspberry Pi 3 Model B+ as control core, Arduino as development platform and battery and electric motor as power was designed. The designed chestnut autonomic harvesting and husking machine can realize autonomic track walking in the chestnut orchard by the control system; the harvest of chestnut can be realized by the rotation of bristle brush with high harvesting accuracy; chestnut husk is removed by the extrusion of PTFE hoses driven by the rotation of twin rollers. The whole machine has simple structure and strong practicability, which can provide suggestions for further improving the production efficiency of chestnut.

Key words: chestnut（Castanea mollissima BL.）, harvesting, husking
