ECE 791/792 Project Proposal The Goddard Project

Team Goddard Advisor: Professor Miller Cassandra DeNunzio Robert Galli Kevin Tierney Andrew Felicetti Samuel Cordeiro Cameron Perl

Meet Goddard Goddard is the robotic dog from Nickelodeon’s popular 90’s TV Series, The Adventures of Jimmy Neutron Boy Genius.

Goddard Project Goals Goals have been divided into four tiers to distinguish between core and stretch goals. The purpose of dividing the project into tiers is to ensure the completion of basic functionality before stretch goals are attempted.

Tier One CAD Drawing of Body Completion of the Body Structure Controlled Movement (Wired) Basic Goddard Features Bark Lights

Tier Two Basic Actions Wireless Interface Basic Proximity Awareness General Acknowledgements Stay Come Bark Wireless Interface Basic Proximity Awareness

Tier Three NodeJS Server Voice Controls Autonomous Movement Speech to Text Software Text Parsing WolframAlpha Integration Text to Speech Autonomous Movement Tail Wag Jaw Movement

Tier Four Fetch Facial Recognition Projector
