Overview and Background


This robot is really easy and cheap to 3d print, build and program. It can be assembled without screws or soldering and it's modular so it can be adapted for different purposes. I'm Swiss, so I don't know American scholastic system but I would use SMARS in last year of middle school, high school or universities/ colleges. There is more "open electronics" compared to a Lego NXT or similar, so students need a few knowledges about security, electrical laws and so on. It can be use to improve software development skills, CAD skills or electronics skills, students can design their own modules and customize their SMARS.

Programming SMARS

You can use most common small hardware platforms as the brains inside SMARS, the Arduino platform (and compatible) was used in the original design as its cheap, commonly available, and the tools for programming it are easy to use. For the quad version of the robot a Raspberry Pi Zero was used. The language commonly used on the Pi (and where it gets it name from) is Python. A library module has been written for both Arduino and Python to help you get started.
