Line-Following Seed Dropper Robot Kit with Arduino Mega
Build an Autonomous Seed Planting Robot with Arduino Mega
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Modern agriculture demands exact seed placement to maximise yield and reduce waste. This kit lets you engineer a 2WD robot that tracks a crop line with TCRT5000 IR sensors, counts wheel rotations through LM393 encoders, and triggers a servo-activated dropper to plant seeds at measured intervals. By day's end, you'll hold a working prototype of industrial-scale precision farming-built from the PCB up.
What You'll Build
A fully autonomous mobile planter that follows a dark line on a light surface, calibrates its travel distance using encoder feedback, and deposits seeds every few centimetres. The 0.96-inch OLED display shows real-time seed count, battery voltage, and odometry data. The double-servo dropper mechanism reliably releases one seed at a time, mimicking agricultural singulation.
What You'll Learn
- Multi-sensor integration - fuse IR line readings with rotary encoder pulses for closed-loop path tracking.
- PID-based motor control - tune L298N driver outputs so the robot stays centred on the line even around curves.
- Servo timing algorithms - sequence SG90 servos to dispense seeds accurately without jamming or double-dropping.
- Real-time status feedback - program the OLED and manage dual 18650 power supply for field-like endurance.

Who This Kit Is For
Designed for B.Tech ECE, EEE, and Mechanical Engineering students prototyping agricultural automation solutions. Equally valuable for Smart India Hackathon agriculture-track participants, VIT/NIT/IIT engineering clinics, and agricultural researchers developing IoT-enabled seed planters. The advanced integration of sensors, actuators, and real-time control mirrors real-world industrial machinery.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project - accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
The AI companion breaks each debugging step into interactive prompts; if you need human backup, message us on WhatsApp and an engineer will reply within hours.
Can I adjust the seed drop spacing?
Yes-the Arduino sketch includes a configurable variable for distance between drops. The AI guide walks you through rerouting servo timings after calibration.
Does this kit require soldering?
Minimal soldering for the encoder connections and OLED header is recommended; we include a soldering iron and solder wire, and the video guide shows exactly where to solder.
Will the robot handle outdoor field conditions?
The TT motor chassis and line sensors are optimised for indoor test tracks or smooth outdoor paths. With proper calibration, it can operate on dry, even surfaces, making it a valid proof-of-concept for agricultural robot design.
