SimpleSumo is an awesome little open source robot which allows anyone to build their very own autonomous mini-sumo with no prior knowledge in robotics at a price that everyone can afford! Designed with education in mind, I created the 'SimpleSumo' platform to lower the barrier to entry into the robot sport of mini-sumo. These robots are easy enough to understand and build that kids can get started quickly, but they also offer great depth through Mr-potato-head-style mechanical customization and Arduino programming. These toys are intended for small groups, ages 10+. Assembly takes ~1hr and requires minimal tool use and absolutely no soldering or breadboarding. Adult supervision is suggested for students who are younger than high school level. **Complete & partial robot kits are available at this link, or you can print and gather everything yourself from scratch using these 3d printable files. https://engineerdog-webstore.fwscart.com/ **For the full assembly instructions & up to date shopping list visit this page on Instructables.com: https://www.instructables.com/id/SimpleSumo-Educational-Fighting-Robots/ **For an up to date list of programs and where to find all things SimpleSumo, visit: https://engineerdog.com/simplesumo **The files included are enough to build the complete standard kit. For upgrades beyond that I chose to sell the 3d printable files in order to recoup my substantial R&D costs.
