Industrial Object Counter Pro Kit - Build a Mini Sumo Robot with Arduino Uno & IR Sensors

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

From the first time you watch your compact robot autonomously track an opponent's infrared signature and push it out of the ring, you'll realize this kit teaches far more than wiring. It transforms a handful of components into a genuine mini sumo competitor - and with a quick code swap, the same hardware becomes an industrial object counter that tallies items on a conveyor with the precision of an entry-level automation module.

What You'll Build

You'll assemble a two-wheel drive robot on a 2WD chassis, equipped with two front-facing TCRT5000 IR modules to detect opponents and two rear-facing ones to sense the edge of a sumo ring. Every time the robot locks onto a target, it darts forward; when it nears the white border, it reverses and reorients. In object-counter mode, a single front sensor counts passing objects while the robot remains stationary, displaying the tally on your computer screen through the Arduino serial monitor.

What You'll Learn

• Calibrating IR proximity sensors to distinguish between black surfaces, white ring edges, and reflective objects
• Controlling DC motors with an L298N driver using PWM signals from Arduino Uno
• Writing conditional logic for autonomous navigation and edge avoidance in a sumo ring
• Reprogramming the same hardware for a real-world industrial counting application

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Students participating in mini sumo contests at college fests (IIT, NIT, BITS, VIT) will appreciate a chassis and sensor set pre-rigged for ring-edge logic. CBSE Class 11-12 physics project makers can use the object-counter mode to demonstrate sensor integration, while ATL Tinkering Labs facilitators will find it a ready-to-run lesson in autonomous robotics that covers both mechanical assembly and Arduino programming.

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.
