Setting up a new Operating System on Turtlebot3

Download Image: ROS Noetic Ubuntu 20.04

Instructions:

1. Flash the image into a microsd card using an imager (dd for linux, or RPiImager).

2. Connect the Turtlebot to a monitor and keyboard, insert the microsd card and turn on the bot.

3. Log into the turtlebot with the username: ubuntu and the password: ROSlab134

4. You will want to remove the tailscale information using the following commands:

       sudo apt-get remove tailscale
       sudo rm /var/lib/tailscale/tailscaled.state
       sudo nano /etc/hostname 
       # change the hostname in this file from "roba" to your robot's name
       sudo reboot now
       

5. Once the turtlebot is rebooted, change the hostname and reinstall tailscale:

       sudo apt-get install tailscale
       sudo tailscale up --authkey=ask-pito-for-code
       

6. Now update the OpenCR board with the following commands:

       export OPENCR_PORT=/dev/ttyACM0
       export OPENCR_MODEL=burger_noetic # or waffle_noetic if you have a waffle tb3
       rm -rf ./opencr_update.tar.bz2
       wget https://github.com/ROBOTIS-GIT/OpenCR-Binaries/raw/master/turtlebot3/ROS1/latest/opencr_update.tar.bz2 
       tar -xvf opencr_update.tar.bz2 
       cd ./opencr_update
       ./update.sh $OPENCR_PORT $OPENCR_MODEL.opencr
       

7. Once the OpenCR board is updated, shut down your bot and turn it back on and you are done with the setup.
