Build a Variable-Strength Magnetic Sorting Robot with Raspberry Pi 5 – AI Robotics Kit

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Imagine a robotic arm that scans a cluttered table with its camera, finds a stray steel washer, and picks it up — not with a gripper, but by precisely activating an electromagnet with just enough force to nudge it into a bin. This kit turns a Raspberry Pi 5 into the brain of a sorting system that varies magnet strength through PWM, letting you handle delicate ferrous parts without crushing them. You’ll build a complete AI robotics pipeline that combines vision, servo motion, and adaptive magnetic control.

What You'll Build

You’ll assemble a 4‑degree‑of‑freedom robot arm equipped with a 12V electromagnet and a Pi Camera Module 3, creating a vision‑guided magnetic sorting station. Place a mix of screws, nails, and paperclips in its workspace, and the system will identify, classify, and pick up each ferrous item, dropping it into labeled containers. The variable PWM control lets you adjust grip from a gentle attraction for tiny pins to a firm hold for heavier bolts.

What You'll Learn

• Control multiple servo motors via PCA9685 and I2C communication
• Vary electromagnetic field strength using PWM signals and a MOSFET driver
• Integrate a Pi Camera for real‑time object detection with OpenCV or TensorFlow Lite
• Build an end‑to‑end AI robotics pipeline from sensing to physical actuation

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

B.Tech ECE and EEE students working on automation or robotics projects will find this kit a ready‑to‑deploy platform for final‑year demos. Participants in the Smart India Hackathon or similar competitions can prototype object‑sorting solutions faster. Hobbyists from ATL Tinkering Labs or robotics clubs at IITs, NITs, VIT, and BITS also benefit — the vision‑based magnetic control introduces a unique technique rarely covered in standard starters.

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.
