Wireless Hummer ECE 791 – Oral Project Proposal ECE Faculty Advisor: Dr. Richard A. Messner November 1, 2010 Presented By: Justin Audley, Blake Brown, Christopher Dean, Andrew Russell, and Andrew Saunders

Contents What do we want to Accomplish? Problem Statement Background Design Specifications Goals Testing/Implementation Estimated Budget Project Timeline

What do we want to Accomplish? Use Kingsbury as a testing ground Remote control car into UGV Control UGV over WIFI UGV Sense Environment Video Streaming

Problem Statement First Response Personnel Safety Rescue attempts Enter and Exit Strategies

Background Remote Controlled Toy Hummer UGV – Unmanned Ground Vehicle – Military operations – Gather information about environment – User can control/observe situations from a distance – User can analyze the data from the UGV to create a well planned entry and exit strategy

Background Disable RF Connection Internet is Everywhere Why WiFi Connection? – More Accessible – Longer Range – Simpler implementation scheme for video transmission

Design Objectives Power Management Transmission and Receiving Migration Issues Bandwidth Usage Ideas to maintain throughout project Why won’t you connect?!

Goals There are two tiers of goals for this project: Deliverable Goals Reach Goals

Goals - Deliverables Control with WiFi Adding on-board sensors for obstacle and relative motion detection Implement video streaming capabilities

Goals - Reach Autonomous movement Elevator Accessibility Audio Streaming Laptop Power Storage (Client and On-Device)

Testing/Implementation Implementation Problems Control API Onboard PC containing software control interface (Control API) interfaced to a Microcontroller through RS-232. Microcontroller is interfaced to vehicle motors via an H- Bridge and to steering servo via microcontroller PWM output. Remote Control Onboard PC supporting WIFI. PC runs server software allowing client software on remote PCs to connect and access the features of the Control API.

Testing/Implementation Implementation Problems Odometry Optical Mouse Mapping Physical Environment Sonic Rangefinders Automation Onboard PC server software with added automation wrapper for the Control API with features accessible to connected client software. 10/25/10
