Indoor Localization Systems

  1. 1. CSCI 7000: Advanced Robotics<br />By: Niket Shah<br />Indoor Positioning SystemDesign Review<br />
  2. 2. Agenda<br />Current Localization System<br />Goal<br />Survey of different technologies<br />Possible Solution: RSSI based Position Estimation<br />Possible Solution: Details<br />Implementation Issues<br />
  3. 3. Current System<br />PDP uses StarGazer Modules<br />Output: [X,Y] Co-ordinates along with orientation<br />Problems:<br />Very Costly<br />Power Consumption<br />Form Factor<br />
  4. 4. Goal<br />Alternative solution to StarGazer<br />Cost Effective<br />Rapid Prototype<br />Acceptable Accuracy<br />Scalable<br />Integrate with existing Localization Framework<br />
  5. 5. Survey: Technologies<br />Wireless<br />Wi-Fi based Indoor Localization<br />RSSI based Triangulation: Zigbee/ISM band SoCTranscievers<br />CSS (Chirp Spread Spectrum): NanoTron’snanLOCtransciver<br />Scene Analysis: StarGazer, Kinect/OpenSLAM<br />Ultrasonic: Cricket, ActiveBat<br />Proximity: IR, RFID<br />
  6. 6. Possible Solution: Triangulation<br />
  7. 7. Possible Solution: TI’s CC2431 SoC<br />2.4 GhzZigbee, Low-Power Transceiver<br />In-built Hardware Localization Engine<br />
  8. 8. Issues<br />RSSI vs Distance: Non-Linearity<br />Additional algorithms required<br />Survey of location to create RSSI Map<br />Orientation detection (Digital Compass?)<br />Multi Level positioning (MEMS Pressure Sensor?)<br />Budget, Logistics<br />
