Access to the robots

E-Pucks

Bluetooth is the preferred access method for the e-pucks.

Bluetooth

(to be added)

S-Bots

Wifi is the preferred access method for the sbots.

Wifi/WLAN

In short: How to access?

Drop the following aliases into ~/.ssh/config. Afterwards you are able to connect to the desired sbot simply by using 'ssh sbot8' for example, whereas the number is the same as on the sbots.

#
# SSH config for the IRIDIA sbots.
# In order to connect to the ssh daemon on the sbots, you have to connect
# to the sbot access point 'iridia-bots.ulb.ac.be' using a specific port.
# The connection is then forwarded to port 22 on the requested sbot.
# This definitions are aliases for easier access. The numbers are the
# same as on the sbots.

Technical Details

The robots connect to a dedicated wireless network upon boot. They receive static private IP addresses from the access point. An individual robot can be accessed from the outside by accessing a special port on the access point. For example, the following can be used for accessing sbot8 using ssh:

$ ssh -p 20822 root@iridia-bots.ulb.ac.be
Wireless link

Access point: iridia-bots.ulb.ac.be

  • SSID: sbot
  • WEP-104 key
    • ASCII: swarm-bots-ch

Ports

Access to Ports < 100: port=[prefix][robotnum][port]

  • sbots: port prefix 2
    • port 20622: ssh access to sbot6
    • port 20822: ssh access to sbot8
    • port 20922: ssh access to sbot9

Serial Console

I (Arne) made two serial console access cables. They are marked with sbot serial console access and should be flying around in the arena. Connect the small red plug to the sbot connector on the left of the power-on switch. It's slightly under the microphone board, so you might want to remove it (but you can do without). The program of choice for connect to the robot is minicom. Use

$ minicom -s

for setting it up. The connection details are: 115kbaud, 8N1, no flow control. Your port should be /dev/ttyS0 if you have a real serial port, or /dev/ttyUSB0 if you're using the USB-to-serial adapter (should be flying around in the arena as well). Then, use

$ minicom -o

to connect to the robot. Upon bootup, you should see the kernel messages. If you connected after booting, you might have to press <ENTER> one time to get a prompt. Please note that you might have to be root to use minicom.
