Robotino v1 and v2
Robotino up to version 2 is equipped with an internal access point. This internal AP can be configured as client or master.
Robotino v3
The next generation Robotino will use an USB WLAN stick to either connect to an access point in client mode or provide a access point external clients can connect to in master mode. Various WLAN USB adapters are supported. The following list shows the USB sticks tested to work in both client and master mode:
- AVM Fritz!WLAN USB Stick N (support for a/b/g/n)
The following adapters are known to work at least in client mode:
- Alfa AWUS036EW USB WLAN Stick (support for b/g)
- Alfa AWUS036H USB WLAN (support for b/g)
WLAN master
The WLAN master on Robotino is run by hostapd. A german how-to on setting up a WLAN router using hostapd can be found here. Additionally a DHCP server is running assigning IP addresses to clients connecting to Robotino's access point.
When running as WLAN master Robotino has the fixed IP address 172.26.1.1 with netmask 255.255.0.0. The DHCP server assigns addresses in the range 172.27.1.100 to 172.26.1.200.
Configuration:
- /etc/hostapd.conf
- /etc/default/isc-dhcp-server
- /etc/dhcp/dhcpd.conf
- /etc/network/interfaces
- /etc/udev/rules.d/99-wlan.rules
- usr/local/bin/start-wlan0-master.sh
- usr/local/bin/stop-wlan0-master.sh
WLAN client
In client mode the WLAN interface of Robotino connects to an external accesspoint. Robotino can be assigned a fixed IP address or can obtain an address from an external DHCP server.
Configuration:
- /etc/wpa_supplicant/wpa_supplicant.conf
- /etc/network/interfaces will contain the line wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
