I have been building hobby robots for quite a while now, and have
discovered in the last couple of years that the way the robot looks
has a major impact not only on how others see the robot, but how I
feel about it and how much I enjoy working on it. The more I can
personify the robot, the more I "like" it. My early robots were very
utilitarian:

They were interesting to build and program, but not very engaging.
Later I started making them "cuter":
http://www.robotguy.net/front.jpg
http://www.robotguy.net/ralph5.jpg
Originally this was by accident. The placement of the sensors looked
like eyes, etc, but after I realized the effect this had on people's
reactions to the robot I started purposely designing for this kind of
look.
Even more recently I have been attracted to the idea of adding emotion/
personality to a robot to further the anthropomorphizing that seems to
be taking place. I have done some studying of how to use the limited
resources available to a hobby robot to express emotion and
personality:

http://robotguy.net/notebook30-31.html
My ultimate goal is a Deskpet. A small robot that lives on your desk
and invites interaction and emotional attachment. It would play games,
react to its surroundings, and interact with the user, but not require
the kind of care and support needed by, say, a Tamagotchi.
My whole point behind that extended introduction was to foster some
discussion of robot aesthetics and personality. What have you done to
make your robots more attractive? Is anyone in the group doing any
research/building along these lines? Any ideas or comments to share?

Excellent observations, and right on.
While I do feel that the utilitarian style is perfectly good for us
experimenters, to entice those outside our craft it's often necessary to
endow the robot with some kind of emotional pull. I saw that very
recently when I showed a video of the Big Dog robot to friends and
family. They all felt "sorry" for it when the person tried to kick it to
make it fall down (it didn't, which was the purpose of the
demonstration).
Along similar lines, Scott Savage (OOPic guy) and robot designer Ted
Macy have been working on an interesting project they are just about
ready to ship, the ooBug. I haven't seen one yet personally, but it
looks like its feature set is in line with your thinking. Perhaps close
to your Deskpet maybe. It has enough processing power and sensors
already on board to do things like exploring and interaction. (Doesn't
have a camera, but I wonder how hard it would be to add a small one.)
Here's a video I just found of it doing a light-following behavior. It's
all software:
http://www.youtube.com/watch?v=-TWJnbYZYtI
It has a bio-look to it, as your ralph5.jpg, which I've found to be
particularly important for the young ones. REALLY gets them interested.
I think also that sound feedback is very important. Not so much talking
to the robot (though it helps) but music, sounds, and even voice
responses. I know this is one of the first thing people comment on with
the Robosapien, for example.
As for your question regarding what I've done to give my robots more
personality and aesthetics, I have to admit it's basically nada!
However, I think we're at a cross-roads where this has come important to
the ongoing acceptance of robotic creatures in home, office, and school.

I think the aesthetics aspect is easier to approach and can be solved
quicker.
To me, the aesthetics factor strikes first and most.
Maybe due to great movies like Short-Circuit and upcoming Wall-e.
I realized the importance of aesthetic feel by chance- when on one of
my mobile robots i mounted the ultrasonic sensor as a "head" which was
rotated by a stepper "the neck".
I didnt do that for aesthetics, but save on sensors and use only one
sensor pair to take distance measurements around the robot. (without
rotating the full bulky robot)
The metallic transducers, when rotated appeared as if the robot is
turning his head and looking around for best path to take.
That was function anyway, but the aesthetics made it all more
realistic, and beautiful to look at.
For personality - i don't know how far we can go presently.
- the ideas in your notebook are great, but these effects shall be
generated by some stimuli,
which are either -
pre-programmed
random
random based on time. (like if the robot doesnt get touched
for a while, he gets sad.)
im trying to think/experiment how else we can make it more realistic,
given the current state of hobby processors and size limitations, (and
not attempt to open a University AI lab, - read MI media lab.).
i found more the sensors the better.
(for example using the info from just 1 IR distance sensor, we could
make it smile when distance reduces suddenly.
- the distance could reduce suddenly, in general, when a human
approaches, or a ball approaches...no one is going to throw a chair at
a robot..)
-so smiling seems a nice response.
some thoughts..
Best Regards

Please log in for more thread options Yay! A response! I was starting to think that comp.robotics.misc was
dead.

Agreed. However all effects,even in humans are generated by stimuli,
whether internal or external.
My current thought is to make sure the robot has a form of internal
feedback (food=good, bump_sensor=bad, etc) and goals (increase overall
happiness or get as much attention from its owner as possible), and
then add a learning algorithm that finds a way to attain these goals,
including using expressions of personality. Initially the actions
would be somewhat random, but could be weighted by "reflexive"
behaviors or by some sort of "personality wieghting" (moody, happy,
morose, levelheaded, etc). As the algorithm got feedback it could
control for instance, what the robot does when he doesn't get touched
for a while, by choosing from a list of actions that have been shown
to lead from his current state toward the current goal state (get
attention). Obviously this would require loads of memory, but
shouldn't be too tough to program for a decently small set of states
and goals.
Did that make any sense?

Please log in for more thread options yes it all makes sense.
it also sounds practical for a tiny microcontroller (say 16bit, with
few hundred kB flash, and some data eeprom to save "learned goals" or
part of flash used as data-flash if the chip allows.) iff the set of
inputs, actions and goals is limited to small sets.
i think this has been implemented to some extent on Abio etc.
