The infrastructure of our living labs is modular and can be reconfigured to meet different experimentation requirements and scenarios, thanks to the use of a variety of wireless and mobile furniture and equipment that can be found in the market. The latter range from wireless sensor networks and actuators to smart devices such as smartphones, tablets and a mobile robot. The hardware infrastructure is described in the following.

Indoor Detection and Location Tracking Systems:

  1. Cricket: It is indoor location tracking system that is used by any agent to track humans or objects position accurately. A socket server provides fine-grained location information of Cricket beacons : space region identifiers, position coordinates X,Y and Z, and orientation. The Cricket native location computing system have been improved to correct deployment and measurement drawbacks. The Cricket beacons are installed on the mobile robot and Raspberry Pi to track respectively the robot and human positions in the ambient space.
  2. Active RFID: The RX202 from Wavetrend provides instant reporting of all detected Wavetrend active RFID tags. It allows user configurable tag data and read range filters. It is installed on the Kompai Mobile Robot and on Rasberry Pi modules through USB connection. The latter can be deployed in any location in the living space.
  3. Passive RFID: The RoboticsConnection RedBeeTM RFID Reader is a sophisticated reader that can work in standalone, or Networked BPAN (Broadcast Personal Area Network) mode. The reader is designed to work with all EM41xx family 125 kHz RFID tags including cards, buttons, capsules, disks, key fobs, and others. A wireless connexion can established between the The RedBeeTM reader and Robot or Mobile Raspberry Pi module by using XBee Zigbee wireless module, which acts as a wireless serial interface.

Energy and Light Management:

  1. ZPlug Boost is a wireless Power Outlet which can be switched On/Off by Zigbee™ protocol. It can commute 16A devices on 220V/230V. It measures the instantaneous power and cumulated consumption of the connected device.
  2. Zlum is very low power Zigbee™ wireless actuator that is used to control lighting system.

Environment sensing:

  1. Doors opening and closing detection: The ZDoor is very low power Zigbee™ wireless sensor. It detects opening and closing of doors or windows with a magnet and reed-switch mechanism. ZDoor is compliant with Zigbee Pro 2007 stack and can be easily add in an existing network. This sensor is installed on cupboards doors, fridge as well as doors and windows of the living environment.
  2. Measuring ambient temperature, humidity and luminosity : The TelosB mote platform is an open source, low-power wireless sensor module that allows measuring RSSI, temperature, temperature, humidity and luminosity. The TelosB is compliant with IEEE 802.15.4. TelosB runs a Contiki embedded operating system.
  3. Motion detection: ZMove is a Zigbee™ passive infrared sensor (PIR sensor) that measures infrared (IR) light radiating from objects in its field of view in the ambient space. Motion detection events are send as alarms to the central node by the Zigbee™ wireless network.
