openag_brain_install_rpi

This repository for installing the openag_brain project on a Raspberry Pi. Unless you are going to be modifying the openag_brain code, you probably want to use the Docker setup instead of this script.

To set up the project, simply clone the repository and run the install.sh file.

git clone https://github.com/OpenAgInitiative/openag_brain_install_rpi.git
cd openag_brain_install_rpi
./install.sh

This will install the ROS environment, all dependencies, openag_python and openag_brain.

Source files for openag_brain can be found in: ~/catkin_ws/src/openag_brain.

Working with ROS

To run any of the openag commands, you must first activate the catkin workspace as follows:

source ~/catkin_ws/devel/setup.bash

(or, you could instead add this to your .bashrc)

Running openag_brain happens through ROS, using the rosrun command:

rosrun openag_brain main -f default

openag_python commands are available globally via the openag command.

Running as a service(background) using systemd

You can set up openag_brain to run at startup using the linux builtin systemctl command:

sudo systemctl enable openag.service

Using for Development

If you want to contribute to openag_brain, or hack on the core system, this script is useful for setting up a development environment.

Building Docker Images

To build new Docker images from openag_brain, you'll also want to install the Docker command line tools. Running the install_docker.sh script from openag_brain_docker_rpi on your Raspberry Pi will take care of installing these for you.

Once Docker is installed, building images is easy. Just:

cd ~/catkin_ws/src/openag_brain

and

docker build -t openag/rpi_brain .

You can provide your own tag/name in place of openag/rpi_brain. See Docker's docs on the build command for more.

Note: we've had trouble with Raspbian's Pixel desktop freezing while building Docker images. We've also had problems with Docker builds failing on Rasberry Pi 2 when no swapfile is configured. We recommend the following build setup for best results:

  • Use a Raspberry Pi 3
  • Make sure to configure a swapfile
  • Use Raspbian Jesse Lite (not the Desktop version)
  • ssh into your Pi and start the build over ssh
