This section will help you get your robot set up to go. Note that if you received this from the Autonomous Robotics Lab then part of these steps may already be done.

See the important information about turning the robot on and off here: Using the Robot.

MicroSD Card (if needed)

If your robot was set up by us, then you should skip this step!

You are going to load software onto the microSD Card - which will wipe out what you loaded onto it according the the instructions before. We provide you a disk image on which to store it. It changes from time to time. is to a google folder that will contain the versions. You should use the latest one in that folder. I recommend you use the app "Balena Etcher" to copy the image onto your microSD card.

To create a new MicroSD from the old one, see

Connecting to the network

Now we are facing a dilemma. We need to get the robot on your network. There are several ways of doing this. Below are two specific scenarios that we support:

1. A usb keyboard, usb mouse and a HDMI display and eduroam wifi access

2. OR A network cable and non-eduroam wifi access

3. A MiniRover v2 and non-eduroam wifi access. It should be labeled with a name.

Scenario 1

1. We will tell you what the name of your robot is. Plug it in below wherever you see gopigo3

2. Locate a wired network connection (on your router for example) and use a network cable to connect your robot to the network

3. Now turn the power on (see for instructions. It should boot up into linux. But you won't know this because there's no keyboard or screen!

Once this works you know that you have access to the robot from your remote computer. Make note of the robot' ip address. It will likely look like 192.168.1.xx but not necessarily.

1. Now use ssh (secure shell) to get to the robot from the remote:

It will ask you for the password for account pi. It is raspberry. Once you get in you are 1/2 way there!

1. Now we want to get your robot onto your local wifi network. You need to know the wifi network's name and password. On the robot command line type:

Where <SSID> is the network's name. You can surround it in quotes if there are spaces or other funny characters. is the password.

1. Next shutdown the robot nicely (see above), disconnect the network cable, and start the robot up nicely again (see above.)

2. Once it's back, follow the same steps to ssh pi@gopigo3.local and enter the password raspberry and you should have a wireless enabled robot.

Scenario 2

1. Connect your mouse, keyboard and screen to the Raspberry pi. You will find several free USB ports and an HDMI port. Look closely they are all there.

2. Boot up the Raspberry Pi and wait until it is running and you see the desktop

3. Locate the network settings dialog box by clicking the network icon on the top right

1. Finally shutdown the robot, unplug the keyboard, mouse and monitor and reboot

2. Once it's back ssh pi@gopigo3.local and enter the password raspberry and you should have a wireless enabled robot

Scenario 3 incomplete and incorrect

You've received a fully set up and tested Minrover v2, and you know the name. The following steps are written as if the robot is called mr1. Scenario 3 Robots will have the account ubuntu with the password ubuntu (so different from scenario 1 and 2)

1. Now turn the power on (see for instructions. It should boot up into linux. But you won't know this because there's no keyboard or screen!

2. MiniRover will come up as a Wifi access point. The SSID is mr1XXXX where XXXX is part of the MAC address. The wifi password is robotseverywhere.s Connect to it via your computer's wifi.

Troubleshooting ssh gopigo3.local

Under certain circumstances gopigo3.local will be found. If so you need to find out the ip address of your robot when it is on wifi (not wired). If then this should work:

Updating the hostname of your Robot

Rename the hostname of your robot. It comes to you called "gopigo3" but they are all called that and this can cause confusion. Let's say you want to call your robot pitosalas. Oddly you have to change it in two places. Here's how"

Now the robot is called pitosalas and at least it will be different from other miniRovers.

Eduroam

On eduroam it is often automatically known as gopigo3.dyn.brandeis.edu. So after rebooting it check if this works. It's not guaranteed but often it works just fine.

VPN

You can run everything on the robot itself but it doesn't have a screen. You could plug an external screen, keyboard and mouse and have a complete ROS enabled computer (the robot) at your finger-tips. But it would be real slow. So instead we are going to add the robot to a "VPN" - virtual private network which will allow you to work with it remotely.

1. Prepare the VPM configuration by:

1. Setup VPN

1. myvpnip should now return that same IP address.

Updates for your Robot

We have installed some Brandeis specific software which should be updated:

And then edit the new ~/.bashrc according to the instructions in the file.

Updates to your Cloud Desktop

1. Check that you have ~/rosutils directory on your cloud desktop. If not:

Edit .bashrc according to the instructions in it

This will continue to be updated
