Licensing

You can do whatever you want.

Objectives

The goals of this project are:

  • Give Elixir coders access to the EV3 via EV3DEV -- DONE --
  • Implement a function domain language for interacting with the EV3 brick --DONE --
  • Take full advantage of processes and OTP to implement a "society of mind" model, with perception, motivation, behavior and actuation. --DONE--
  • Implement a robot control panel in Elm and Phoenix. --DONE--
  • Get two robots to interact and even cooperate. --TBD--
  • Having fun! -- so far so good --

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 - WiFi works on Linux)
  • 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/ev3; mix compile; node_modules/brunch/bin/brunch build; pushd /projects; tar -cf ev3.tar --exclude=".git" --exclude=".*" --exclude=".gitignore" ev3; scp ev3.tar robot@192.168.1.100:/ev3.tar; popd; 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.
