Automatic Pet Feeder Kit: AI Object Detection & 4-DOF Servo Arm
Automatic Pet Feeder Kit: AI Object Detection & 4-DOF Servo Arm
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Give your cat or dog a timed, portion-controlled meal without ever touching a button-this advanced build uses a camera, inverse kinematics, and a four-axis servo arm to detect your pet, pick a scooper, and deliver food into a bowl. The project runs OpenCV object detection on a Linux-based single-board computer (like a Raspberry Pi, not included) that computes the precise joint angles for the arm, then sends targets over serial to the included Arduino UNO Q. You'll assemble, wire, and program an AI-driven pet care station that bridges vision, motion control, and embedded systems in a single working prototype.
What You'll Build
A fully functional prototype that watches a feeding zone with a camera, identifies your pet using a trained OpenCV model, and activates a 4-DOF servo arm to scoop and dispense dry food. You'll calibrate the arm's inverse kinematics so it reaches the food container, picks a measured amount, and places it in the bowl with repeatable accuracy-all triggered automatically when your pet is hungry.
What You'll Learn
- Implement real-time object detection on a Linux MPU with OpenCV and Python.
- Calculate inverse kinematics for a 4-DOF arm and convert joint angles into servo positions.
- Interface the PCA9685 servo driver over I2C from an Arduino to control MG90S servos smoothly.
- Integrate computer vision feedback with embedded hardware to build a closed-loop automation system.

Who This Kit Is For
This kit is engineered for B.Tech ECE/EEE students tackling final-year AI-mechatronics projects, Smart India Hackathon teams needing a ready-to-integrate vision-and-motion platform, and serious hobbyists from institutes like IITs, NITs, VIT, or BITS Pilani. You should be comfortable with Python, basic Linux usage, and soldering; a separate Linux-board (not included) is required to run OpenCV.
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 walks you through each connection and calibration step, and you can send photos over WhatsApp for real-time human backup.
What computer do I need for the AI vision part?
A Linux-based single-board computer (e.g., Raspberry Pi 4) with Python 3 and OpenCV installed. It is not included but the camera and all electronics are ready to interface with it.
Can I control the feeder over WiFi?
The stock build runs local processing; you can later add an ESP8266/ESP32 module (not included) to enable IoT dashboards or remote triggers.
How do I ensure the servo arm moves accurately every time?
Our build guide includes an inverse-kinematics calibration routine. The AI companion explains servo angle limits and helps you fine-tune the math to avoid overshoot.
Pet Care - OpenCV object detection on Linux MPU computes IK target. STM32 drives 4-DOF servo arm via PCA9685.
