  1. Radiation Level Mapping Using An Unmanned Aerial Vehicle Reducing Human Exposure in Dangerous Environments

  2. System Block Diagram

  3. UAV Platform • GauiQuadrocoptor • High lift capacity • Large battery for extended range • Can carry Geiger counter • Uses Ardupilot • Open source • Easy to integrate custom sensors

  4. Ardupilot • Wireless Telemetry using Xbee • Serial Communication with Geiger counter circuit • Gain tuning for project specific airframes

  5. Geiger Counter • Geiger-Muller tube to detect radiation • Analog circuitry to filter signal • Single pole low pass filter

  6. Cortex-M0 • Precise time base for Geiger counts • Offload some of the responsibility from the Ardupilot • Fully interrupt driven • Buffered counter • Reduce spikes • Ability to measure background radiation levels

  7. KML Writer • Record data from Quadrocopter GPS and Geiger counter while in flight • Generate map of flight path and Radiation levels

  8. Problems and Deviations from Original Plan • No obstacle avoidance • Reduced the scope of project in order to complete other goals • Crashes • Airframe breakage & rebuild • Circuitry damage & replacement

  9. Special Thanks • Andrew Karpenko • Loaned Xbee Modules • Tom • Installaed necessary software on lab computers
