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.
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.
Design Model
Survey of Literature, Market, and
Existing Solutions
• Many researches about odor tracking robot
• Spiral Surge Localization algorithm
• Conducting polymer-based odor sensor
• Odor-guided locomotion – Dr.Mark Willis
Originality and Creativity
• Interface requirements
– LabVIEW TM
– Other modules
– Dilution system (E-nose)
• Client needs
– Odor dispersion
– Odor source detection
Constraints and Feasibility
• Constraints
– Language
– Time table
– Ignorance
• Feasability
– Low cost
– Time?
– Sensor response
Alternative Solutions
• Webots robot simulation language from
Cyberbotics
• Java and Visual Basic languages
• Adding win sensor
• Coding just one model instead of two
Design Validation
• Module validation
– Accuracy & performance?
• Compatibility
– Interface with other modules?
• System testing
– Complete the project goal?
Economic Analysis
• Little or no costs
– Possible cost: $220 for robot simulator
• Whole project implemented in software
• Software and dilution system provided
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
Management, Scheduling,
