Areca nut is one of the major commercial crops grown in Southern parts of India. During the rainy season the arecanut crop gets attacked by disease due to fungi. This makes the half grown arecanut crop to decompose and fall. The major concern in this sector is the lack of skilled labor and safety issues for spraying pesticides and harvesting. Currently, the pesticide spraying is done manually by climbing the tall trees. This is much difficult, risky job, because the person has to climb the tall tree, which is also slippery in rainy season. To avoid the risky job, in this project a supporting lightweight small plate at the operating level just above the ground, centrally carries a long pipe. This plate is supported between two arecanut trees by flexible ropes and springs. The sprayer fixed at the top can be controlled from the ground level. The long pipe carries the pressurized pesticide from ground to the top, which is to be sprayed to the half-grown bunch of arecanut fruits. This project idea helps in such ways that, the person need not to climb the tall tree, but he can spray the pesticide by standing on the ground itself.

INTRODUCTION Number of researchers developed various techniques and devices intended to climb the tall areca nut tree for spraying pesticides or for garnering the crop, etc. In rainy season the half-grown arecanut crop suffers from a fungal disease due to heavy rain. To save the crop from fungal attack, it should be sprayed with pesticides. But spraying the arecanut situated at tree-top which is about 15m is a risky and difficult task. Due to continuous rain, the tree surface becomes slippery to climb. In the past, the pesticide spray was done manually by climbing the tree. Due to labour shortage and non-availability of skilled labor, people started developing machines to avoid the tree climbing manually. Many researchers have developed devices using different ideas and designs. Each researcher used typical mechanisms in their device for climbing the tree. Some have used mechanical linkages and working without electricity, some others have developed semi-automatic tree climber and plucker attached with machine vision. The safety of the climber was on focus and many have avoided manual tree climbing in their device. Whereas some have developed automated robotic pesticide sprayer for arecanut. Few researchers developed a drone for arecanut harvesting successfully. Attempts were also made to develop an arecanut tree climbing device using fuel engine which can move vertically up or down along the by remote control.
2. LITERATURE REVIEW A literature review of articles about arecanut tree climber and pesticide sprayer is carried out is given below. R. Thirupathi et al.,[1] in their project developed a climbing machine which has spring and pulley and harvest the nut. The developed device is fully depending upon mechanical linkages and spring actions without electricalpower. Mohit Rane et al.[2], proposed a semi-automated tree climber and plucker machine which can climb and harvest. The device has wirelessly controlled and a machine vision is provided by a camera to get clear vision of the crop at high altitudes. This machine eliminates the need of tree climbing manually and hence operator safety is increased and fatigue is reduced significantly. Sudarshan
