Agenda Project Overview Needs Assessment Concept Development Analysis & Synthesis Detailed Design Attributes/Requirements map Challenges / Risks Senior Design II

Overview - Objective Design a physical scale model of a generic landscape with vehicles and human robotic structures to simulate human and vehicular motion across varying terrains and realistic scenes.

Overview - Background Video processing research in object tracking and recognition Used in surveillance applications Testing algorithms analyze video captures Current videos capture real life and synthetic scenes

Overview Current algorithm testing methods Problems –Object positioning –Object motion –Light intensity Solution –Moving vehicles / people –User controllable speed –User controllable lights

Needs - Key Requirements Low cost – less than $1000 Light control Portability Roads, alleys, buildings, trees, hills User controllable vehicles User controllable human robotic structures Build to scale

Needs - Subsystems Physical stationary scale model User controllable vehicles User controllable robotic structures

Needs - Timeline Fall Quarter –Design Model and Vehicles Winter Quarter –Design Human Robotic Structures Spring Quarter –Fabricate entire model
