• Components
• LEGO MINDSTORMS NXT (computer-controlled brick
  that acts as the brain of the iBot)
• LEGO MINDSTORMS Ultrasonic Sensors (enables
  the iBot to see, measure distance to an object,
  and react to movement)
• LEGO MINDSTORMS Vex Parts (basic building
  materials)

Abstract iBot is essentially a replacement for
the everyday seeing eye dog used by the visually
impaired. iBot was designed to be a more
efficient set of eyes for the blind, as it does
not need to be fed, groomed, trained, or taken
care of after its creation, unlike a live dog.
The implications of using this robot do not
include putting humans out of work, an important
idea behind the design of iBot. Our hope is that
iBot will change the lives of millions of
impaired people around the world.
Conclusion As challenging as this project was, it
was very successful. iBot guided its impaired
owner down a city street, across a street with
cars and other moving objects, around a
stationary object, and to its destination. We
had many setbacks in our development, including
changing the components and even the software.
Nonetheless, the iBot successfully acted as a
robot seeing eye dog, guiding our blind
individual down the model city street unscathed.
Additional Benefits Guide dogs around the world
are often mistreated, neglected, and
underappreciated. Also, in many countries
regulations or rules deny access to animals such
as guide dogs in restaurants and other public
places. Without dogs being used as guides both
of these problems will be solved. The iBot was
designed to solve more problems than just guiding
the blind.
