As seen at the San Diego Maker Faire, we developed this kit with the San Diego Makers Guild as an easy way to build a cardboard bot that is controlled via a smartphone or tablet.

Wait, you're telling me you don't have any idea what a cardboard sumo bot is? The rules are simple, just use your bot to push another bot outside of a circle drawn on the ground. You can even add weapons, like a flipper, to the bot to gain an advantage. A video taken at the 2018 San Diego Maker Fair is embedded below.

This AddiKit also makes a great robot platform for experimenting with servos and sensors and allows for expandability.

Addicore also offers this kit for education and events. Contact us for more information.
