  6. Coconuts are harvested by climbing the tree and cutting it down with hands. Tree climbing is the only source of income for many families. The job is risky and can result in severe accidents. “Ripe for the Plucking, but Fewer Dare to Try” PROBLEM DEFINITION

  7. Problem Definition “The shortage is caused by two factors. First, the inherent risk associated with the job. Secondly, with Kerala being a relatively prosperous and well-governed state with 100 percent literacy, more and more young people are moving away from this hereditary job. Coconut plucking has been concentrated among the Dalits, or the untouchable caste. As literacy in the state grew and caste system gradually became unshackled, the educated youth no more saw it as a desirable profession. This, in spite of the fact that pluckers can make $8 a day in a country where most earn less that $2 a day.” Courtesy: India reports

  8. PROBLEM DEFINITION • Facing shortage of Coconut Tree Climbers • The job seems simple, but is very risky and dangerous. • Considered as a “Less Dignified Job”! • People running behind White Collar Jobs. • No other efficient harvesting methods at present. RESULT>> Decrease in coconut availability to home users.

  9. Design a Coconut tree climbing ROBOT to achieve the following goals: Can be controlled from the ground Both men and women can operate it The Robot is safe to handle Even an illiterate person can operate it with a little training The Robot is Eco-friendly Simple and less cost PROBLEM SOLUTION

  10. “You can’t climb faster than me…..” “No I can’t. But can u climb more trees than me???”

  11. OUR DESIGN Top supporter Expandable shaft Bottom Supporter

  12. BLOCK DIAGRAM Video Transmitter Camera Robotic hand And cutter Micro controller (P16F877A) RF Receiver Top supporter Expandable shaft Bottom supporter Video Receiver RF Transmitter Joystick Display User

  13. This design has three major parts Climber Robotic hand with cutter Camera display system STRUCTURE

  14. Has 3 parts Top supporter Expandable shaft Bottom supporter CLIMBER Top supporter  Expandable shaft  Bottom Supporter 

  15. SUPPORTER • Each supporter consists of • 2 motors (M1 and M2) • Belt Side view M1 M2 Front view

  16. SUPPORTER

  17. Expandable shaft • 2 servo motors are fixed to Aluminum frames • The position of the shaft can be changed from ‘C’ to ‘I’ and ‘I’ to ’C’ using these motors. • Shaft connected to supporters using hinges

  18. EXPANDABLE SHAFT Motor 1 Motor 1 Motor 1 Motor 1 Motor 1   Motor 2     Motor 2 Motor 2 Motor 2

  19. CLIMBING MECHANISM

  20. ROBOTIC HAND • Robotic hand is made using aluminum frames with servo motor at joints. • A cutter and a camera are attached to the hand. • The hand can be controlled from the ground using the joystick provided to the user. • The position of the hand can be adjusted according to the video received from the camera.

  21. ROBOTIC HAND

  22. RF RECEIVER TRANSMITTER • Used to establish communication between the Robot and Joystick • Operating frequency of RF Receiver Transmitter is 433MHz • 8 bit transmitter receiver • Maximum range of 20m with antenna size 30cm
