Cybert is a mood-driven autonomous robot pet with an unlimited vocabulary! In addition to exploring, playing
games, and getting into mischief, Cybert will soon be able
to tell jokes, report current news, weather, and
stock market information, and find humans and read them
their e-mail messages! When his battery runs low he
can navigate to his charger from anywhere in the house.
Cybert is based around the Cye-sr robot from Probotics,
Inc. A friend helped me add an FRS receiver, a
range-finding sensor, and a light sensor. The robot
communicates with my PC via wireless modems; speech is
broadcast using a pair of 500mW radios (Cybert's mouth
is a small speaker). My Visual Basic program will
eventually be able to parse text from websites, e-mail,
etc. and convert this to speech using Microsoft's
powerful Speech SDK.
TIME TO BUILD: The hardware additions took less than a
day

and "dialogue" every day)

BEHAVIORAL PROGRAMMING:
Cybert chooses most of his behaviors based on his mood.
If he hasn't sensed a human for awhile (and it isn't
night time) he will become uncomfortable. This will
cause him to choose behaviors that are known to make him
feel better, such as moving into a well lit room.
His mood also determin
