Certified that the project work entitled “Arecanut Tree Climber and Pesticide Sprayer” Two nozzles are placed on either side at the top of the machine with. Arecanut trees attain a height of about feet. It is mandatory Considering all the casualties in conventional tree climbing we decided to make a robot that. In this context, this project work presents “Areca nut Harvesting Machine.” Here we are designing and fabricating areca nut tree is.

But they are not successful as the input for them is muscular power of the labour and it requires a person to physically climb the tree to cut the crop or harvest the nuts.

For harvesting the nuts, and for spraying and applying insecticides on the crown, skilled labourers have to climb the tree manually. Skilled arecanut tree climbers have become scarce and farmers are finding it difficult to harvest the nuts. Hence harvesting fruits and nuts and maintaining them becomes difficult. Therefore, maintaining sufficient friction force capable of handling the self-weight, maintaining the stability of the structure while in motion, reducing the total weight, and achieving the precise gripping are the important parameters that have to be considered.

Climbin trees like coconut tree, arecanut tree, and palm trees are so tall that climbing them becomes risky. It is fitted with three DC motors – nylon tyres with rubber grippers at degrees each other for ease of the operations. Pulley and a brake cable is used to ensure smooth movement of the links.

Areca nuts are collected in a basket. Tref are much equipment machines in the market to help the farmers in this regard. Arecanut climbing and spraying machine 3.

Mqchine diagram to calculate Length of the links Figure 2. Sukesh K S Type of entry: Climbing Mechanism and Working The arecanut tree climbing and spraying machine works on the basic principle of friction that is the relative lateral motion of two solid surfaces in contact. In recent years, labour scarcity has emerged as one of the foremost challenges in farming.


It provide the very essential torque for the setup to climb up and come down along the length of the tree.

Remote Control Unit 5. DC geared motors having reduction gears which ensures self-locking of the tyres and thus maintains maachine height. Length of Link Length of each link is taken as 58 cm, the calculations are shows below and line diagram to calculate length of the links is shown in figure 1.

It is the heart of the setup. It is the main source through which torque is generated.

Climbing Mechanism and Working 3. So development of a unique tree climbing mechanism is necessary which may be used for maintaining and harvesting applications.

The machine is having a triangular shape, hinges are provided on each links for the movement of links with the variation in size of the tree. Torque Calculation Calculating motor torque, 4.

Areca Nut Tree Climber, Model No.: ATC

The nozzle is mounted on top of the guide way motors. Line diagram to calculate Length of the links. The machine can be connected and detached from the areca nut tree easily.

This is the most suitable machine for harvesting areca nuts without man climbing on the tree. The geared motor should be powerful enough to carry the climning and weight of the machine.

Driving wheels are machined from nylon rods having diameter of mm which is used to provide firm grip and also to operate the machine so that it climbs the tree easily. It also requires greater agility and high manoeuvrability to be used as a product. Power from the battery is supplied to the motors using flexible wires and DPDT Double Pole Double Throw switch is used to control the movement of climbing machine as well as spraying unit. The machine should be capable of adjusting to the varying cross-section of the tree during upward and downward movements.


When a rope attached to the machine is pulled from the ground; the machine climbs on the tree.

The DC motor used to climbbing wheel is square geared DC motor. The design and fabrication of arecanut tree climbing and spraying machine is presented in this paper. A spring is used to provide sufficient grip to the wheel on the tree according to the change in the size of the tree.

In this tree climbing machine power is obtained from 12V battery through which drive motors are energized. The spraying is done in monsoon, while harvest time is typically in summer. The device has been tested for its performance and found safe, reliable, and efficient and also reduces the problems in climbing and spraying arecanut tree to a good extend.

Selection of the Wheel Average Change in circumference of the tree is taken as 30cm to 50cm. It requires skill to climb arecanut tree. The remote is used to control the motor. The only component which is in contact with the tree is the wheels which are made up of nylon. Also the bark of some trees may not be strong enough to bear the weight of the climbing device, hence conventional climbing machine cannot be used for tree climbing applications [].

The machine can be used for spraying insecticides also. Remote control circuit Figure 4. This project has a simple and low cost areca nut climbing machine, which can help generate employment in rural areas.

Guide way motors are rotated to the required position in order to spray pesticide to the crop.
