Guided Electric Rover
OBJECTIVE Design and build a rover that can be
driven remotely around a building using a
wireless internet connection.
APPLICATIONS Tour guide, portable video
conference, inspection, retrieval, security, etc.
  • RESOURCES
  • Designed and built in one semester by a senior
    design class composed of 12 students from the
    Electrical Engineering, Computer Engineering, and
    Wireless Engineering programs.
  • Self-funded approximately 50 per student
    (total of 600).
  • Minimizing cost required significant effort -
    salvage parts from defunct projects, build
    instead of buy, etc.

H-bridge Motor Driver
  • SPECIFICATIONS
  • Capable of being operated either remotely via
    internet connection or by a wireless controller
    in close proximity. Proximity operation
    supersedes internet link.
  • Continuous two-way video/audio accessible through
    any internet connected PC. Video quality must be
    sufficient to readily identify room numbers and
    names on hallway nameplates when passing.
  • Onboard video camera has 360 degree field of view
    capability, camera can be rotated remotely.
  • Vehicle must have user-friendly, adult human-like
    form factor suitable for use as a tour guide.
  • Must have fail-safe or backup in case of any
    foreseeable hazard such as loss of internet
    connection, driver error, rapid appearance of an
    obstacle, etc
  • Must use zero or low emission rechargeable power
    supply suitable for indoor operation.

  • RELATED RESEARCH THEMES
  • Effects of variable internet time delay
  • Cooperative robotics
  • Human-machine interaction
  • Autonomous guidance and control

ONBOARD USER INTERFACE
  • CONCLUSIONS
  • Design was successful, but only due to highly
    self-motivated students.
  • Program affiliation (ELEC, CPE, WIRE) quickly
    gave way to collaboration and teamwork.
  • Difficult to operate with bandwidth afforded by
    802.11b.
