Installation

The easiest way to get started with the Mighty Thymio is to use docker.

1. Start with a fresh minimal image with Ubuntu 16.04

• Download the lastest image from the official Odroid repository.
• Flash the image to the eMMC card.
• Switch on the Odroid, log in and run the odroid-utility to expand the filesystem.
• Bring the OS up-to-date

  apt update
  apt install linux-image-c1
  apt upgrade

• Install git and curl

  apt install git-core curl

• Reboot

2. Clone this repository

   mkdir -p /root/docker
   cd /root/docker
   git clone https://github.com/jeguzzi/mighty-thymio.git

3. Run the install script

   cd /root/docker/mighty-thymio/install
   source install_local.sh

4. Bring up the docker containers

   cd /root/docker/mighty-thymio
   docker-compose up -d robot ui ups camera

Shutdown and restart

The software will automatically restart on boot. To properly shutdown the robot, either run

sudo shutdown now

or press the up arrow (the button on top of the robot's body that points towards the back) for 6 seconds.

Demo

We also include the Docker Compose file to launch the demo

cd /root/docker/mighty-thymio
docker-compose -f demo/ml/docker-compose.yml up

Software update

Connect the robot to the internet and either run

cd /root/docker/mighty-thymio
source do_update.sh

or hold down the right arrow (the button on top of the robot's body that points towards the right wheel) for 6 seconds.

Troubleshooting

After starting, the Thymio is not blinking

1. check that all cables are connected
2. login into the odroid
3. check that docker is up

   systemctl status docker

   If not, reset docker:

   systemctl stop docker
   rm -r /var/lib/docker/runtimes
   rm -r /var/lib/docker/containers/*
   systemctl start docker
   source /root/docker/mighty-thymio/do_update.sh

4. check that the services are up

   cd docker/mighty-thymio
   docker-compose ps

   If not, recreate them:

   source do_update.sh
