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
