Summary
We demonstrate the interoperability and the dynamism capabilities in SCA-based systems in the context of robotic for smart habitats. These capabilities are due to two developed tools: a Python-based OSGi runtime and service-oriented component model (Pelix and iPOPO, respectively) and a tool to publish SCA services as OSGi services (NaSCAr). By this, we have developed a robot service and a pilot' user-agent, which can dynamically add and remove sensors and widgets. This use case follows and responds to the ubiquitous computing trend and the runtime adaptivity needed in such systems.

Robot
RobAIR (Robot for Ambient Intelligent Room) is based on the Wifibot robot. The Wifibot had a chassis with 4 wheels geared by 4 DC motors with hall encoders. The Wifibot is controlled by an Atom D510 main board running under Linux (Kubuntu 10.04) or under Windows CE.

Wifibot' nuiltin sensors are
 * PTZ webcamLogitech QuickCam® Orbit AF ou Logitech Quickcam Sphere AF
 * Hokuyo Lidar (URG-04LX-UG01 communication protocol spec.)
 * Infrared sensors (left and right)
 * Battery level sensors
 * Odometer

For the demonstration, we have plugged several additionnal sensors on the available USB ports (remark: USB hubs are not correctly managed by the current OS distribution). Several analog and digital sensors are soldered on an Arduino shield piggybacked on an Arduino UNO board.
 * Geiger counter Sensor
 * Arduino board with:
 * LPG gas sensor (MQ-6)
 * Methane gas sensor (MQ-4)
 * Carbon monoxyde gas sensor (MQ-7)
 * Flame Detection Sensor for flame detection
 * Ultrasonic Distance Sensor
 * Wii Motion Plus I2C Gyroscope
 * Inforad K1 NMEA 0183 GPS Receiver

Extra sensors are
 * XBox Kinect for depth images and webcam
 * 139741 Arduino Infrared Obstacle Avoidance Detection Photoelectric Sensor for stair/hall detection (Arduino board)

Extra actuators are
 * scream out loud - 110dBA fixed tone Siren (controlled by a relay on the Arduino board)

Pilot's Console

 * PC with USB game controller ou Nunchuck+Arduino UNO
 * Android phone or tablet

Component architecture
The robot's embedded software and the pilot's console are developed using 2 SCA composites. Inner components are developped in Python and in Java/OSGi. Components and Composites are bound using four types of SCA bindings : direct reference, local socket, UPnP, XMPP/Jingle (and SIP/Simple but not in this demonstration). The SCA containers are : NaSCAr/iPOJO for Java/OSGi and iPOPO/Pelix for Python. iPOPO components wraps C/C++ native libraries (ROS) and scripts (Urbiscript).

XMPP/JINGLE
We have modified a GTalk-compliant user-agent (JISI) according to the robot and the pilot requirements.

UPnP Profiles
The Robot publishes 1 UPnP device profile and 6 UPnP service types. Remark: The Robot1.xml device profile embeds optionally a device with the standardized Digital Security Camera Profile (DCP) for each on-board webcam (or Kinect).
 * Robot1.xml (file)
 * Chassis1.xml (file) for driving the chassis
 * Sensor1.xml (file) for analog sensors
 * CompositeSensor1.xml (file) for multiple value analog sensors
 * DistanceSensor1.xml(file) for Lidar, IR and Ultrasonic distance sensors
 * PositionSensor1.xml (file) for GPS
 * IM1.xml (file) for Instant Message and Visioconferencing

SCA Binding
OASIS had already specified SCA bindings for main stream protocols used in B2B and EAI. Our goal is to defined SCA bindings for protocols widely accepted in SOHO (Small Office Home Office) networks (ie UPnP) and in videoconferencing (ie XMPP/Jingle and SIP/SIMPLE).

UPnP SCA Binding
The UPnP SCA Binding implements 1 UPnP device profile and 6 UPnP service types.

IM Binding
The IM SCA Binding implements the session establishment for XMPP/Jingle.
