Problem Background

• E-nose came about from trying to mimic the sense
  of smell in robots or machines.
• E-nose beneficial because
• -Not fatigued
• -More sensitive
• Research now is focused on putting an E-nose on
  a mobile robot

Problem Statement

• Develop signal-processing procedures to
  reconstruct the changes in concentration of odor
  mixtures through the response of a gas sensor
  array.

6
Design Objective

• Create three modules
• -E-nose module
• -Diffusion module
• -Robot Simulator
• Replace E-nose module with provided dilution
  system to test with real sensor responses.

• -Odor source detection

11
Constraints and Feasibility

• Constraints
• -Language
• -Time table
• -Ignorance
• Feasability
• -Low cost
• -Time?
• -Sensor response

12
Alternative Solutions

• Webots robot simulation language from Cyberbotics
• Java and Visual Basic languages
• Adding win sensor
• Coding just one model instead of two

13
Design Validation

• Module validation
• -Accuracy performance?
• Compatibility
• -Interface with other modules?
• System testing
• -Complete the project goal?

14
Economic Analysis

• Little or no costs
• Possible cost 220 for robot simulator
• Whole project implemented in software
• Software and dilution system provided

15
Societal, Safety, and Environmental Analysis

• Many benefits
• -Locate harmful gases or leaks
• -Test air quality and monitor emissions
• -Help in space exploration
• Few risks
• -Slow response in dealing with harmful odors
• -Robot malfunction

16
Management, Scheduling,and Teamwork

• Four jobs
• -Head Manager Simon Saugier
• -Time Coordinator Ninh Dang
• - Documentation Coordinator Greg Allbee
• -Head Programmer Jason Hamor
