Noetic Robot Software Setup

Get software installed and the car running

Beginner Tutorial | Expected duration is 30 - 60 minutes

By: Matt Schmittle


This tutorial will get your car up and running teleoperation.


To get you driving your car around in teleop.


The following are required before continuing with installing the necessary libraries.

  • SD card flashed with the latest NVIDIA Jetpack image. Under “Installing JetPack” click the drop-down menu for your hardware and follow the “Getting started …” tutorial
  • A way to connect the computer to internet (either WiFi or ethernet)
  • Monitor, HDMI cable, mouse, keyboard

Booting Up

Power on and boot the Jetson. Make sure your sd card is plugged into your Jetson Nano and flush, this should be done from the hardware tutorial. If you have an AC to 5V power adapter you can plug that into the barrel connector on the USB port side of the Jetson Nano. If not, place a battery in the right side of the car and plug the connector into the matching connector going into the top half of the car. Plug in the right angled barrel connector into the Jetson Nano. The green light on the right side should turn on. The correct configuration is shown below. For initial setup you will need to plug a monitor, keyboard, and mouse into the car. The keyboard/mouse can go in any of the USB ports, intial setup does not require the sensors to be connected.

Everything plugged in correctly. Notice the barrel connector in the top right, the battery in the right slot, and the green light in the top left.

2. Follow the on-screen prompts to complete setup of the Jetson Nano operating system. If you would like your setup to be consistent with our tutorials, we suggest using the following values:
Username: robot
Name: robot
Computer Name: goose

Setup Wi-Fi

If you want to install additional software on the car, or be able to use the internet on your laptop while connected to the car then you will want to set the car up with a static IP. A static IP is a IP address (think postal address but for talking between computers) that does not change each time you connect to wifi. Most computers do not have a static IP, but for regularly connecting to the robot we do not want the robot’s IP to change.

Once logged in, use the mouse to click on the Wi-Fi icon in the top right and click “Edit Connections” to open the network manager. Connect to the network that the robot should have a static IP on.

Highlight the connection that corresponds to the network the robot should be connected to and click Edit... or the gear icon.

Click on the General tab and check that Automatically connect to this network when it is available and All users may connect to thisnetwork are enabled.

Click on the Wi-Fi tab. Make sure that the SSID: field is set to be the name of the network that the robot will have a static IP on. In the example image, it is University of Washington. Make sure that the Mode: dropdown is set to Client. In the Device: dropdown, choose the last option.

Click on the IPv4 Settings tab. Set the following fields:

  • Method: dropdown to be Manual.
  • Click Add. Under Address, enter:
    • The Static IP: for example 172.16.77.Z.
      Z is usually the robot number on the car, but it’s up to you!
    • Netmask:
    • Gateway:
  • DNS servers: field, enter

Click the Save button and close the connection editor.

Reboot the Nano.

After the Jetson reboots, verify that the robot has obtained the expected static ip.

$ ifconfig
Check wlan0 is the IP you set.

SSH from another Computer

Once the Nano has fully booted, it will connect to the existing network at the specified static ip. You should then be able to ssh into it (with a separate computer on the same network) with the static IP you set earlier.

$ ssh robot@172.16.77.Z

Connect the bluetooth controller

Note the column of icons on the left-side of the Ubuntu GUI. Click on the uppermost one, and type Bluetooth. Use the search result to open the Bluetooth dialog. Turn on the PS4 controller by pressing on the Playstation button. Note that the controller must first be charged using a USB-mini cable. The LED on the front of the controller should flash. Put the controller into pairing mode by simultaneously holding down the Playstation button and the Share button. The LED on the front of the controller should continuously emit quick flashes.

Next, in the Devices sidebar, click on the plus icon in the lower left corner. In the dialog that pops up, choose Input devices(mice,keyboards,etc.) in the Device type drop down. There should now be a single entry labelled Wireless Controller. Click it, and then click Next in the lower right corner. After the dialog reports Successfully set up new device ‘Wireless Controller’, close the Bluetooth dialog.

Setup Docker & Install MuSHR stack

Now we are going to install MuSHR. Fortunately, robot setup is similar to the simulation setup. Follow the following from the noetic quickstart tutorial.

  • Installing Docker
    • IMPORTANT NOTE: Only install docker-compose as the nvidia-docker/docker is pre-installed for the specific hardware
  • Installing MuSHR Docker Container
    • NOTE: when ask “Are you installing on robot and need all the sensor drivers? (y/n)” respond “y” so that the sensor drivers are installed.

Unlike simulation, visualization usually is run on a separate computer (though you can install Foxglove on the robot). From the noetic quickstart tutorial complete the following steps on your separate visualization computer.

  • Downloading Foxglove Studio

Working with the stack and Launching Teleoperation (manual driving)

Because we are working with docker, there are a few things to note about how to work with the stack.

First, all ROS commands must be run inside a docker container. Docker containers are created via the mushr_noetic command. If you need to create multiple terminal sessions we recommend entering one docker container then using tmux (pre-installed). That way you only need to remember to run mushr_noetic once.

Second, the code itself resides in ~/catkin_ws and is attached to the docker container. This allows you to use your favorite editor and tweak code outside the container. Code edited outside the container will automatically be updated inside the container so there is no need to restart a container.

Teleoperation (manual driving)

Turn on the car and vesc by plugging their batteries in. Enter the docker container.

$ mushr_noetic

Then run teleop

$ roslaunch mushr_base teleop.launch

You should see the lidar spinning and be able to steer with the controller. While holding down the left bumper, use the left joystick to throttle, and the right joystick to turn. See diagram below.


After starting up, the robot terminal should print out a line similar to

Rosbridge WebSocket server started at ws://

In Foxglove, click the top button in the sidebar, labeled Data Source. Then select the Plus button in the left panel. This should open up an interface to connect to data.

Click the Open Connection button. Select Rosbridge (ROS 1 & ROS 2) as shown below.

Fill out the WebSocket URL with the robot’s IP and port that the simulator output before. For example if you set your robot’s IP to then it should be ws:// The IP will differ from the one pictured. Then, click Open in the bottom right corner. The left sidebar should show that a connection has been made.

On the right of the middle panel it will say map. Click on that and switch it to car/base_link. A red laser scan should appear.
