Wow! Cool! I'm excited! In that case, I should mention a few things:
* Most of the Sophia code is in the opencog github repos.
* For trademark reasons, the open-source code should be called "Eva" not
"Sophia", we decided that was the proper way to avoid trademark issues.
* Anyway, the code is now many years out of date; Hanson Robotics has moved
to a proprietary code base, which is not available.
* The code "used to work"; there are docker containers that pull in
opencog, blender, the Eva blender head model with all of its animations,
USB-video for vision, microphone+text-to-speech for sound. The problem is
that the code in the opencog repos was moved around, changed, renamed, so
the docker containers are surely broken. I could show you (or anyone else
who is interested) in how to get that working again.
* There is little/no actual "AGI" in that code base. What it does do is to
hook up blender and opencog (and video, etc.) to ROS, so that the Atomspace
contains a description of what the camera sees (faces, via face detection),
and so that the AtomSpace can control robot movements (smile, blink, turn
left, ...). The actual animation is done with Atomese scripts ("behavior
trees") that encode things like "when a new person becomes visible, turn to
face them (coordinates x,y,z) and smile". She's actually calibrated, so
that it looks like she is really looking at you (the blender model turns to
face you) based on the USB camera coordinates; she'll track both with eyes
and with head.
* There was some prototype code so that you could verbally command her
("Eva please smile" and she would, "Could you turn left?" and she would)
and some code to ask her what her current state is ("Eva, what are you
doing?" "I'm looking left") But that prototype code is not "AGI" -- it is
scaffolding to hook up vision and motor control to a "model of the world"
and a "self-model", in such a form that natural language could access that
model ("Eva what are you doing?") and to change that model ("Eva, blink
three times"). The model, the representation of the world, needs to be in
a form where both the language subsystem, and the other subsystems (vision,
motors) could work with it.
* The plan was then to grow that model using automated learning techniques;
this would be the actual AGI. However, that is still a long ways off. I'm
working on learning right now, but it is not yet in a form where it could
be hooked up to a robot (and is surely many years away; it's a big task,
and I can only work part-time on it, and I've been unable to find funding
for it, or to recruit any significant amount of help.)
Anyway, that's the status. I'd be thrilled to talk more! I hope your
master's proposal gets accepted!
