Sumo Robot Kit with Arduino Uno + IR Sensors
Sumo Robot Kit with Arduino Uno – Build Your Own Mini Sumo Competition 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.
Imagine the thrill of your own robot pushing an opponent out of a ring. This sumo robot kit equips you with everything to build a compact, rule-compliant mini sumo bot that uses front-mounted IR sensors to hunt down rivals and rear sensors to detect the ring edge, keeping you in the competition.
What You'll Build
You’ll assemble a fully functional 2-wheel-drive sumo robot that can autonomously search for an opponent, detect the white boundary line, and execute a pushing strategy. The robot’s chassis, motor driver, and Arduino Uno form the core, ready for battle in mini sumo events at school or local maker fairs.
What You'll Learn
- Calibrating TCRT5000 IR sensors for line and obstacle detection
- Programming Arduino Uno for autonomous navigation logic
- Interfacing L298N motor driver to control two TT gear motors
- Powering the robot with 18650 lithium cells and managing battery life

Who This Kit Is For
Perfect for ATL Tinkering Lab students and school robotics clubs entering inter-school mini sumo competitions. Young enthusiasts aged 10–15 will gain genuine microcontroller and sensor integration experience. Also ideal for first-year B.Tech (ECE/EEE) students exploring autonomous robotics, or anyone building a starter project for Smart India Hackathon prototypes.
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?
Scan the QR code on your kit box to access the AI build companion specifically trained on this sumo robot. It provides step-by-step debugging help. You can also WhatsApp us for human support.
Can I use this robot in an official mini sumo competition?
Yes, the assembled robot meets the standard 10 cm × 10 cm footprint and 500 g weight limit for many mini sumo events. The four IR sensors match competition-spec line and opponent detection. You may need to add a lightweight top cover (not included) if full enclosure is required.
Does the robot work on black lines over a white ring floor?
Absolutely. The TCRT5000 sensors are highly sensitive to the high contrast between the white surface and the black boundary line. The kit includes extra resistors and capacitors that let you tweak detection thresholds during calibration.
Can I add more sensors or modules later?
Yes. The Arduino Uno has spare digital and analog pins, so you can attach ultrasonic distance sensors, a gyroscope, or even a Bluetooth module. The AI companion includes guidance for common expansions once you master the basic robot.
Compact robot with front IR sensors to find opponent and rear sensors to detect ring edge in a mini sumo competition.
