The Semi-Automatic Durian Harvesting and Transport project was developed to address safety and efficiency challenges in durian farming. In provinces such as Vinh Long, Tien Giang, and Ben Tre, durian harvesting still relies heavily on manual labour, exposing workers to safety risks from climbing tall trees and handling heavy, thorny fruits. Traditional machines are unsuitable for durians due to their unique weight, protective needs, and delicate handling requirements. The team set out to create a Bluetooth-controlled automated system that reduces physical strain, enhances worker safety, and protects fruit quality throughout the harvesting and transport process.
HOW DOES IT WORK
The system operates through a smartphone interface connected via a Bluetooth Module (BT18), with an UNO R3 microcontroller at its core processing commands and controlling DC motors through BTS7960 motor drivers across three channels:
- Remote positioning: The operator uses a smartphone app to navigate the machine beneath durian trees, eliminating the need for climbing
- Safe harvesting platform: Workers cut durians from a stable platform while fruits drop gently into a cushioned catchment basket, preventing damage
- Controlled lowering: The basket descends slowly into the main container, protecting fruit quality and integrity
- Automatic transport and unloading: Once full, the machine navigates to the collection point and tilts the basket to transfer fruits onto trucks effortlessly
The system functions seamlessly from orchard to collection point. In the field, operators position the machine under high durian trees, cut the fruit, and watch it land safely in the basket. During collection, the machine automatically moves to the pickup area and tilts to load fruits onto transport vehicles, saving time and reducing manual handling.
IMPACT
The Semi-Automatic Durian Harvesting system combines automation, IoT, and agricultural technology to create a practical solution for real-world needs. It demonstrates how students can apply coding, engineering, and problem-solving skills to address meaningful community challenges—from improving worker safety to modernising traditional farming practices in Vietnam’s Mekong Delta region.
