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.

PROBLEM SOLUTION
• 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

FUTURE PLANS
• To make the system capable enough to
automatically recognize the coconut to be
plucked without human assistance.
• Identifying a portable power source with
maximum efficiency.
