The Robot's Serial Number is your individual Robot's unique identifier. It is also the default hostname that can be used to connect to the robot without previous configuration.
Finding the Serial Number
You can find your Sawyer's Serial Number (S/N) on the back of the robot (on the panel where you connect the cables).
Default Robot Hostname
Each Sawyer Research Robot comes with the robot computer's hostname set to the serial number of the robot. Sawyer can be addressed out of the box using this hostname via Avahi (Link-Local) addressing.
For example, if Sawyer's serial number reads 'S/N: 011303P0017', then the hostname will be '011303P0017', and the avahi local hostname will be broadcast as '011303P0017.local'. You can then run commands such as:
$ ping 011303P0017.local
or, resolve the robot's IP address using:
$ avahi-resolve-host-name 011303P0017.local 011303P0017.local 192.168.32.210
Note: Make sure you have the avahi programs installed by running:
$ sudo apt-get install avahi-autoipd avahi-daemon avahi-utils
The default hostname can be changed using the Field Service Menu (FSM).
