![Introduction
• Timely response of first responders is crucial in rescue
operations.
• First responders inundated with streams of data from
sensors (machine + citizen).
– “Emergency responders have to assimilate large amounts
of information in very short periods of time” [Cowlard et.
al].
• Streams of data when interpreted with domain
knowledge, results in abstractions.
• Abstractions (intuitive to humans) makes first
responders respond quickly in rescue environments.

- 3. Motivation – Environment ignorant • Machines without any sensors http://www.familycourtchronicles.com/philosophy/dissonance/remote-control-car.jpg
- 4. Motivation – Environment sensing • Machines with sensors Photo courtesy NASA The autonomous Urbie is designed for various urban operations, including military reconnaissanceand rescue operations.
- 5. Motivation – Environment comprehending • Machine with sensors + perceiving background knowledge + comprehending background knowledge Traffic signals Google’s car that won the DARPA challenge. pedestrians Stimuli and others on roads.

- 6. Project Focus • Building a rescue robot (mobile-platform) with many sensors. • Data Collection and annotation using SSN ontology. • Analysis to be carried out for situational awareness using perception ontology [2]. • Visualization of the emergency situation in terms of abstractions.

- 8. Data Collection + Annotation • Collection of data from sensors on the robot. – Position data: Observation form position sensors. – Sensor data: Observation from environment sensors. • Annotation of raw sensor data. – Use of SSN ontology which has concepts to describe sensors and their observations. Raw Sensor Data Robot (Mobile Platform) With Sensors Position data Position Data Stream Sensor Data (CO2, Temperature, IR, CO data.) Annotated Annotated Paper on Fire Data (triple Data Stream store)
- 9. Perceptual Analysis • Perceptual ontology used to derive abstractions from annotated sensor data. • Domain knowledge is used to derive these abstractions. Annotated Sensor Data Abstraction Stream Perceptual Reasoning Domain Knowledge Images: http://static3.depositphotos.com/1001416/130/i/950/depositphotos_1304999-Sheet-of-the-old-scorched-paper-and-fire.jpg http://www.firesystems.net/images/portable-fire-extinguishers/types-1.jpg http://www.blogcdn.com/www.engadget.com/media/2007/02/irobot-packbot-510.jp
- 10. Visualization • Visualization serves as a dashboard for presenting real-time: – Raw sensor data – Position Data – Derived abstractions – Video of the robot

- 12. Conclusions • Robot with perceptual abilities give out abstractions that are intuitive to humans. • Demonstrated a real-time physical system that uses domain knowledge to process heterogeneous sensor data. • Demonstrated visualization of events (as abstractions) in an emergency situation in real-time.

Hinweis der Redaktion
- Machines interpreting the sensor data and sending only abstractions to the humans would be ideal. Else, the human has to interpret the sensor data which is not intuitive for humans.
- Note: No free food! Someone has to do the processing!Machines/HumansIf traffic signal is red, then stop.If there are pedestrians crossing the road, then stop.If the speed limit is less than the current speed, slowdown.
