The Ubiquity defaults to providing a WiFi Access Point (AP) to allow for easy initial communication. Usually, this should be changed so that the Ubiquity logs onto one of your personal networks.

Logging on in AP Mode

The Ubiquity’s AP will appear in your computer’s WiFi list as ubiquityrobot**** where **** will vary from bot to bot.

Connect your computer’s WiFi to ubiquityrobot****. Your computer may ask “Enter the PIN from the router label”…click “Connect using a security key instead”…the default key is “robotseverywhere”.

Open PuTTY, connect to 10.42.0.1

You may see:

The authenticity of host ‘10.42.0.1 (10.42.0.1)’ can’t be established. ECDSA key fingerprint is SHA256:sDDeGZzL8FPY3kMmvhwjPC9wH+mGsAxJL/dNXpoYnsc.
Are you sure you want to continue connecting (yes/no)?

Answer yes

Failed to add the host to the list of known hosts (/somepath/.ssh/known_hosts).

Ignore that. 

login as: ubuntu
password: ubuntu

Connecting to Your Network

First, change the hostname so you can recognize the bot on the network:

sudo pifi set-hostname SPUD
sudo reboot

Now the robot’s AP name will now appear as SPUD**** instead of ubiquityrobot****. You will have to connect your laptop to the new name and supply the password again.

Running Some Fun Stuff from PuTTY

move the bot using the keyboard:

rosrun teleop_twist_keyboard teleop_twist_keyboard.py

all diagnostics:

rostopic echo /diagnostics

monitor specific topics by using grep to filter the desired data:

rostopic echo /diagnostics | grep -A 1 'Battery'
rostopic echo /diagnostics | grep -A 1 'MotorPower'
rostopic echo /diagnostics | grep -A 1 'FirmwareVersion'
rostopic echo /diagnostics | grep -A 1 'FirmwareDate'
rostopic echo /diagnostics | grep -A 1 'FirmwareOptions'

• BatteryVoltage key shows the battery level in DC volts
• MotorPower key is True when the ESTOP is enabling wheel power
• FirmwareVersion shows the main board firmware version
• FirmwareDate shows the date for the firmware
• FirmwareOptions shows hardware options if enabled

start some navigation routines:

roslaunch magni_demos simple_navigation.launch
