In delivery state, Navel provides the following services via ethernet and wifi:
  * SSH via port 22
  * Browser interface via port 80

Navel is meant to be connected to a network via wifi. The ethernet connection serves as fallback. You can always connect a computer and access the robot via its static IP address 169.254.254.1.

The browser interface can be used to connect to a wifi network with no authentication or *WPA2-PSK*.


In operation, the robot might establish a connection to the following services:
  * what a Debian system does, e.g.:

    * DNS servers for name resolution
    * NTP servers for time synchronisation
    * APT servers of Debian and navel robotics for software updates

  * pypi, npm registry
