Problem statement
Problem Statement

  • We wish to reduce injury and death to pedestrians and bikers caused by lack of visibility.


System overview
System Overview

  • Users of the road wear GPS devices transmitting their location

  • Motor vehicles have receivers and transmitters

  • Displays the location of received GPS information on the windshield (Heads Up Display)

Mdr goals progress
MDR Goals/Progress

  • I. Learning Phase

    • GPS, XBee, ATTiny, BeagleBoard

  • II. Communication Phase

    • Getting all the components talking to one another

      • Make connections, send and receive data

  • III. Software Phase

    • Write the basic transmit/receive software for each part of the system

      • ATTiny, XBee, BeagleBoard

  • IV. Prototype

    • Get the transmit/receive system working in the proposed fashion


Mdr goals progress1
