Eddie: RDS4 Meets Kinect Meets Parallax

under $15,000 just two years ago, yet these machines
cost a fraction of that and are absolutely amazing. Eddie
almost feels alive to me as does TurtleBot. They both have
the capacity to speak and to understand speech which is
now so easily accomplished with today’s robots.
What’s next? Covering these robots with artificial
skin, giving them a face, and sending them out on the

Should you buy one or build your own? Is Eddie the
best choice or should it be the TurtleBot? I personally like
Eddie — mainly for its size and payload capacity, but that is
my choice. Everyone has their own requirements and needs.
Since both machines have the Kinect sensor system, the
main difference is really the software: ROS or RDS4. Again,
I feel more comfortable with RDS4, but again, that is my
Both platforms have certain superior qualities over the
other as well as inferior points. Eddie is more expensive
but seems to be worth it for its quality and robust
construction. TurtleBot is not nearly as upgradeable for
heavier add-ons since it is quite a bit smaller. TurtleBot
comes with the Kinect and a netbook whereas you must
furnish your own for Eddie — which could actually be a
plus for many experimenters. Do take the time to look
at these machines if you are at least a tiny bit
interested in expanding your personal robotics
knowledge and capabilities by a large magnitude. These
machines add a new chapter to personal robotics
