Compact Arduino-Enabled Micro Sumo Robot Kit for Fast Learning and Competition
The JSumo 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.
Original JSumo product: We list this item as a distributor, so the product title now starts with JSumo for clearer brand matching.
Official-size friendly: JSumo lists the XS1 at under 100 grams and within the common 5 cm size limits, helping it fit official micro sumo robot rules.
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.
