Overview

We have a Tikitag RFID reader, embedded in the door, which we use to automatically open the door when authenticated.

The software runs on Flowers, and its code is on Github.

The access list is currently a text file, copied via a script from Flowers. The text file simlpy consists of card ID and name.

Adding a card

On Babbage:

babbage:~$ cd /usr/local/share/Doorbot
babbage:/usr/local/bin/Doorbot$ sudo git pull
babbage:/usr/local/bin/Doorbot$ sudo ./addid.sh

Then touch the card to the reader next to the Makerbot.

Alternatively, connect to Bell:

root@bell:~$ sudo screen -dr doorbot

You will see the log of attempted access. Press Ctrl+A Ctrl+D to disconnect and add the card manually to cardtable.dat.

The door opener connects to robonaut on Babbage to announce whenever the door is opened, and also flashes the lights on using Lighted, also on Babbage.

Override

ssh root@bell
sudo Doorbot/openDoor.py

The password is hackspace. If the arduino has somehow changed port, you might need to edit that in openDoor.py

  • If this ambiguity becomes a problem (eg if another serial port is added), update the udev rules : debian distributions create /dev/serial/by-id where the links in that directory include in their names the unique serial number assigned to the FTDI chip on the arduino board.
    • This will happen when I/someone gets around to it :D Ms7821 08:38, 27 August 2010 (UTC)

Please use this with caution. Once unlocked, the door must be physically opened and closed again to relock.

If you unlock the door remotely, use the webcam to check someone has entered the space.
