This is BERT, a Buildable Educational RoboT.
BERT is very affordable because it is open source and uses off the shelf parts. BERT is WiFi enabled and only needs a browser to control and program. BERT is a fun and enaging tool to learn engineering, coding, and 3-D modeling.
These stl files are specially designed for easy printing with no supports. A nozzle size of 0.4mm or less is recommended due to the print details. For the best Lego compatibility, we recommend printing parts in PETG.

We hope you enjoy using BERT.
