#Ev3: Lego Robotics in Elixir

Licensing

You can do whatever you want.

Objectives

The goals of this project are:

• To give Elixir coders access to the EV3 via EV3DEV -- DONE --
• To implement a function domain language for interacting with the EV3 brick --DONE --
• To take full advantage of processes and OTP to ease the implementation of complex control software --TBD--
• To have fun!

This project was inspired by Torben Hoffmann. Thanks Torben!

Prerequisites

• You will need a Lego Mindstorms EV3 kit
• A micro-SD card with EV3Dev on it
• Some way to communicate with the EV3 brick (Bluetooth or WiFi)
• Erlang and Elixir installed on both you computer and the EV3

Go to my blog for further instructions, pointers and examples.

Development

I use the following shell script to quickly upload and install code on the EV3 brick:

On my computer's .bashrc file:

alias deploy-ev3='pushd ~/projects; tar -cf ev3.tar --exclude="*.git" --exclude="*.*~" --exclude=".gitignore" ev3; scp ev3.tar [email protected]:~jf/ev3.tar; popd'

On the EV3 brick, in my .bashrc file:

alias install-ev3='pushd ~;rm -r ev3;tar -xvf ev3.tar;popd'

You will need to modify them to fit your own context.
