Overview
Designed and developed a remote-controlled semi-automatic cotton harvesting system to boost productivity for agronomists and farmers. Combined mechanical harvesting hardware, embedded control, and IoT connectivity to handle variable plant heights and limited labor.
The Problem
Manual harvesting is labor-intensive, time-critical, and sensitive to plant height and field variability. Productivity and consistency suffer when harvest windows are narrow or labor is limited.
My Approach
Built an integrated system capable of remote operation with damage-free picking, adaptive height control, and field mobility. Used ATmega2560 for low-level control, Raspberry Pi for coordination, and Wi-Fi for wireless communication. Designed end-effector, manipulator, and chassis from scratch.
Key Results
Ran extended field trials and benchmarked against manual harvesting. Achieved a verified 40% productivity improvement. Delivered a fully functional prototype applicable to small, medium, and large-scale farms.
