Marty V1 is controlled and programmed over WiFi. You can connect Marty to your WiFi network, or if you have a class pack it's easier to use the command hub
School WiFi networks can be complicated to connect to. So, every Marty class pack comes with a little WiFi router that also runs Scratch without needing an external internet connection. We call it a command hub.
It creates a little Marty network wherever you plug it in, and you can connect your Martys and your computers to it
If you don't have a command hub, you can connect Marty directly to your WiFi. There's a one time set up where you tell Marty your WiFi network details, and then every time you turn Marty on it'll connect to that network.
