We designed this Smartibot robot chassis to provide a good sized platform for attaching LEGO bricks to the top and back to make your own creations. A design like this was requested by a user on the Smartibot Reddit forum to 3D print and use in the classroom.
You can find the files, printing and assembly instructions over on Thingiverse.
This is our first attempt at designing one of these, here at Crafty Towers and, seeing as we are very happy with how it has turned out, we don't think it will be the last. If there are more resources like this which you think we could design that would help you do things you want to do with Smartibot please let us know in the forum or on social media.
