What it does
This design solves the issue of rice transplanters sinking in soft soil. It provides an affordable, lightweight, and maneuverable solution for Malaysian farmers, enhancing planting efficiency, reducing soil compaction, and cutting operational costs.
Your inspiration
The decision to solve this problem stemmed from the significant challenges faced by Malaysian rice farmers who struggle with inefficient and heavy transplanters that sink in soft and waterlogged soils. These issues result in decreased planting efficiency and crop yields. During discussions with local farmers, it became clear that a lightweight and highly maneuverable machine would drastically improve their productivity. The idea for the solution emerged from market surveys, which revealed the need for an affordable, sustainable, and effective tool to address these challenges while reducing labour dependency.
How it works
The design features a lightweight rice transplanter for soft and waterlogged soils. It uses an extendable planting arm with a servo motor to adjust depth, ensuring optimal seedling placement. Paddle wheels with sprockets enhance traction, preventing sinking in wet conditions. Floaters made from high-density polyethylene (HDPE) bottles provide buoyancy, keeping the transplanter stable. A real-time soil condition system uses a load cell sensor to detect soil softness and adjust planting depth automatically. The system integrates a GPS module for precise navigation, capturing latitude and longitude of soft soil areas. This data is uploaded to a Google Sheet via Wi-Fi, allowing farmers to track soft soil areas. The LCD display provides clear feedback for easy operation. The design reduces soil compaction, minimises maintenance, and is affordable for smallholder farmers, making it a user-friendly and efficient solution for rice planting in challenging conditions.
Design process
The design process started with identifying the challenges of rice transplanters sinking in soft and waterlogged soils, which hindered planting efficiency. We focused on creating a lightweight machine with adjustable planting depth, better traction, and stability. The first prototype, built with 3D-printed components and a steel frame, revealed issues with weight distribution and depth control. We improved buoyancy by using HDPE bottles for floaters and enhanced the servo motor for precise depth adjustments. Paddle wheels were reinforced with sprockets for better traction. The second prototype incorporated a load cell sensor to monitor soil softness and a GPS module to track soft soil areas, with data uploaded to a Google Sheet via Wi-Fi. The final design improved Wi-Fi connectivity, making it easy to track field conditions. The machine now adjusts planting depth automatically, includes an LCD display for user-friendly operation, and is cost-effective for smallholder farmers. This solution reduces soil compaction, minimises maintenance, and boosts productivity and sustainability in rice farming.
How it is different
The design process began by addressing rice transplanters sinking in soft and waterlogged soils. The first component is the adjustable planting arm with a servo motor for precise depth. The second is the real-time soil condition monitoring system, using a load cell sensor to adjust depth automatically. The third is the paddle wheel system with sprockets for better traction, preventing sinking. The first prototype, made from 3D-printed parts and steel, revealed issues with weight distribution and depth control. Improvements included HDPE floaters for buoyancy, upgraded servo motor, and reinforced paddle wheels. The second prototype added a GPS module, uploading location data to Google Sheets via Wi-Fi to track soft soil areas. The final design automatically adjusts depth, reduces soil compaction, and is affordable for smallholder farmers, improving planting efficiency.
Future plans
Next, we plan to integrate a higher torque motor for better performance in tougher soil conditions. The current motor may not provide enough power for larger fields or rough terrain. Additionally, instead of using HDPE bottles for floaters, we aim to fabricate more durable floaters using moulded plastic or lightweight metal alloys. This would improve buoyancy, reduce wear, and increase durability. These improvements will enhance the transplanter's stability, efficiency, and lifespan, making it a more reliable and long-term solution for farmers.
