A lot of users are trying to install Angstrom in the BBB. This question has already been answered in the FAQ. I put it on the README hoping that future users might realize this fact.

BEAGLE-ROS project

BeagleBone ROS

Integration of the Robot Operative System (ROS) and the BeagleBone through the meta-ros project, a layer for OpenEmbedded Linux.

This project is part of the Google Summer of Code (GSOC) 2013. The aim is to work in the integration of the Robot Operative System (ROS) and the BeagleBone. Both ROS and the BeagleBone are great tools and increasingly being used in robotics. Having both of them working together in a easy way would be a great asset.

A lot of users show their interest for ARM ROS integration. Some made a couple of tutorials about how to install ROS on Ubuntu on the BeagleBoard however this documentation is getting a bit old fashioned and probably not the right way. There's also some code to use lightweight versions of ROS but again, roboticists might not be looking for a light-ROS device but a fully functional one.


It's highly recommended to have the last version of Angstrom.



The Angstrom Distribution web is temporary down. If you wish to set Angstrom up follow [http://www.angstrom-distribution.org/](these instructions).



As answered in the FAQ, Angstrom should NOT be installed in the BeagleBone Black.


##Description of the files:

  • LICENSE: License of the code.

  • README.md: This document.

  • scripts: Scripts to automate processes.

  • docs: Documentation.

  • lib: Libraries used.

  • recipes-ros: OpenEmbedded recipes. These recipes should be used with the meta-ros code.

  • conf: OpenEmbedded configuration directory. This directory is added so that the beagle-ros project can be directly added as a layer in Angstrom/OpenEmbedded systems.

##Dependencies

This layer depends on:

URI: https://github.com/bmwcarit/meta-ros
branch: master
revision: HEAD

USAGE

##Getting roscore running

cd beagle-ros/scripts
source minimal-ros-install-angstrom.sh
  • source /usr/setup.bash. Updates in the ROS recipes doesn't install scripts in the /usr/ directory anymore. To configure the enviroment properly check this bashrc file.

  • run roscore.

##First steps Getting started with Angstrom (or OpenEmbedded) and bitbake might be a bit tough at the beggining but it gets better and after a while you will love it, promised ;). First, take a look at the FAQ.

Beagle-ROS makes use of the meta-ros project, an OpenEmbedded layer that provides ROS to embedded devices. In order to get comfortable with meta-ros the diving-meta-ros repo aims to give you some aid with the first steps (take into account that this tutorial assumes that you are already comfortable with ROS. If not take a look at their tutorials).

##Installing the recipes The easiest way to install the bitbake recipes provided is to git clone the beagle-ros code directly into the Angstrom sources/ directory and add the beagle-ros as a layer:

  • Edit conf/bblayers.conf
  • add ${TOPDIR}/sources/beagle-ros \ to the BASELAYERS variable

It's also possible to add the recipes inside of the meta-ros code. There're instructions in https://github.com/vmayoral/beginner_tutorials/blob/master/README.md of how to put these recipes in the meta-ros file structure. (Here you can see the recipes available).

##Cross-compiling the recipes From the TOPDIR of Angstrom run bitbake <recipe-name>. For example: bitbake beginner-tutorials

(Refer to the FAQ if you wish to cross-compile all the neccessary recipes to have ROS in your machine.)

BeagleBone ROS Packages

Some ROS Packages designed for the BeagleBone:

  • bb_sharp_ir: BeagleBone Shark IR sensors ROS Package.
  • bb_dc_motors: ROS package that launches a node to control a DC motor connected to the BeagleBone.
  • bb_mpu9150: BeagleBone ROS package that publishes the Invensense MPU-9150 data into a Topic.
  • bb_altimeter: ROS package for the BeagleBone that publishes the altimeter MPL3115A2 values to a Topic.

(recipes to cross-compile these packages are available at the recipes-ros folder)
