The Zumo Robot is an Arduino-based tracked robot that is less than 10 cm × 10 cm, which qualifies it for mini sumo competitions. Power is provided by two micro metal gearbox motors, and it features a stainless steel bulldozer-like blade for pushing around the competition. It has six infrared sensors for line following or edge detection, an accelerometer, a magnetometer, gyroscope, and a buzzer, allowing you to play your favourite victory song. No soldering required – just add four AA batteries and an Arduino, and you’ll be all set for some robotic sumo wrestling.
They rate the Zumo 9 out of 10, saying “A clean looking bot.”

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
