ergoCub network

The network on ergocub can be divided in two parts:

internal network (10.0.1.0/24): it connects ergocub-torso to all the motor controller boards on the robot, it is a segregated network (there is no connection from the nodes on its subnet and the ouside world) and it is used to send motor commands from ergocub-torso to motor control boards;
extenal network (10.0.2.0/24): it is managed by the ergocub-server and it connects all the ergoCub machines together, handling the internet connection too. This connection can be wired or wireless;
backup network (10.0.0.0/24): this is a backup/troubleshoot network for connecting directly to the robot in case of not reaching the external network.

ergoCub network interfaces

ergocub-torso

On ergocub-torso, one of the two ethernet interfaces is connected to the internal network. The other one, instead, is directly connected to ergocub-head via backup network.
ergocub-head

On ergocub-head, the ethernet interfaces are bridged together on the backup network.

Both head and torso are connected to the external network via WiFi.

Below you can find the default network parameters of the ergoCub networks.

This configuration depends deeply on the motor control board firmware and thus it can't be changed.

Since this is a segregated network, there is no default gateway.

Usually, it is a static configuration, but it works also in DHCP mode. This configuration can be changed but it is not recommended.
