Build a Competition-Ready Mini Sumo Robot

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

Transform a handful of components into a 2WD sumo robot that actively searches for opponents and refuses to tumble out of the ring. This kit equips you with front-facing TCRT5000 IR sensors to lock onto an adversary and rear sensors to detect the white perimeter line, mimicking real competition behavior. Whether you're preparing for a school tech fest or tinkering at home, you'll have a robot that reacts, retreats, and charges again entirely on its own.

What You'll Build

You assemble a compact robot on a sturdy chassis, powered by dual TT gear motors and controlled by an Arduino Uno R3. Four TCRT5000 IR modules do the heavy lifting - two in the nose to spot opponents and two at the tail to constantly monitor the ring edge. When the front sensors trigger, the robot lunges forward; the moment a rear sensor sees the white boundary, the robot immediately reverses, spins, and resumes its hunt. By the end, you have a mini sumo contender that understands its environment without a single line of remote control code.

What You'll Learn

• Calibrate TCRT5000 IR sensors to distinguish between a dark sumo ring surface and a white boundary line
• Interface an L298N motor driver with Arduino to control bidirectional motion of two DC gear motors
• Write decision logic that switches between search, attack, and edge-avoidance behaviors in milliseconds
• Troubleshoot sensor noise and power distribution - skills directly transferable to line followers and maze solvers

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

CBSE Class 11-12 students assembling a working model for their physics or computer science project will find it hits the perfect complexity level. B.Tech ECE and EEE undergraduates can use it as a ready base for mini project submissions and Smart India Hackathon prototypes. ATL Tinkering Labs and school robotics clubs across IIT, NIT, VIT, and BITS tech fests will appreciate the straightforward assembly - the bot is small enough to carry, yet behaves like a genuine autonomous competitor.

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.
