Compact Arduino-Enabled Micro Sumo Robot Kit for Fast Learning and Competition

The XS1 Micro Sumo Robot Kit is a compact competition-style platform built for makers who want to explore the world of micro sumo robots. JSumo describes it as a great way to begin in micro sumo, with built-in sensors and motors that make it easier to focus on tuning, strategy, and programming.

The XS1 includes 4 sensors made up of 3 opponent sensors and 1 line sensor, plus 2 DC gear motors. It can be programmed with the XMotion Micro Controller based on Arduino software, giving students and hobbyists a familiar development path.

Why you'll love it

• Micro sumo ready: Designed for official micro sumo size and weight targets
• Arduino-enabled development: Easy for code customization and experimentation
• Built-in sensors: Includes opponent and line sensing for faster setup
• Portable platform: Small enough to bring to practice sessions and demos
• Competition-focused learning: Great for strategy, sensing, and tuning practice

What you can build

The XS1 is ideal for micro sumo training, robotics classes, competition demos, Arduino programming practice, and compact autonomous robot projects where size and weight constraints matter.

Starter bundles

Pair it with extra infrared sensors, spare DC motors, a programming setup, and replacement wheels for practice and quick repairs.

Recommended add-ons

Useful add-ons include extra line sensors, spare batteries, charging gear, wheel replacements, and compact tools for between-match maintenance.

Technical specifications

Pinout & usage notes

The XS1 is designed to keep the basic mechanics and sensing already in place, so you can focus on robot behavior, reaction timing, and match strategy. It is a practical platform for students who want to learn how compact robots make decisions in real time.
