Sumo robots are nothing new. Their videos go viral on YouTube, Reddit, and other sites all the time. Thanks to the Parallax SumoBot Robot Competition Kit, you can build and play with your own sumo robots. These robots have a bunch of modules and sensors to detect their opponent and autonomously battle in a Sumo ring. They can be programmed using the BlocklyProp visual programming language.
These robots come with a FLiP Multicore Microcontroller, SumoBot WX circuit board, black chassis, and sticky tires. You get sockets for adding an accelerometer, a distance sensor, and a wireless programing module.
