Creative Brains for Robots
Summary - IEI
builds unique neuro-control systems that enable robots to ad lib tactics and
strategies that exceed their original programming. Fully capable of autonomously
learning from its own mistakes and successes, our revolutionary neural network
paradigms allow complex robots to learn completely from scratch. In a matter of
minutes, the equivalent of 'cybernetic road kill' can learn to walk, recover
from various mishaps, or accomplish some broadly defined mission. While such
creative robots are strictly experimental at this stage and under development
for the Air Force Research Laboratory, we can tailor similar systems for
commercial and private application.
Details -
For the most part, modern robots
designed for industry and the military are termed reactive. They
simply sense various scenarios within their environment and then recruit the
necessary behaviors, in the form of computer code or a deterministic
neural network, to react to such situations. However, the kinds of robots that
we frequently see portrayed in science fiction are called deliberative,
since they appear to accumulate world models and ponder such models when
deciding what to do next. Creativity Machines are the
natural way to implement such contemplative control systems aboard robots, since
the imagination engine may review a wide variety of action plans, while critic
networks may select the strategy most likely to meet the broad objectives of
the system. Furthermore, if the Creativity Machine is STANNO
based, it can learn to perform various feats from scratch, using totally untrained
artificial neural networks.
In the figure to right, for instance, a complex
hexapod robot uses its onboard sonar to judge its forward progress as its
Creativity Machine based control system experiments and cumulatively learns how
to walk. Later, this very same Creativity Machine can enter into a cycle of
experimentation and learning to perfect other types of motion strategies (i.e.,
backward, right turn, and left shuffling motion). In effect, this neuro-control
system emulates the thalamo-cortical loop of the brain, wherein the
cortex imagines various courses of action through noise stimulation, while the
thalamus narrows down the range of possible scenarios prior to motor cortex
implementing the most appropriate of these plans. ...In IEI terms, the
noise-activated imagination engine corresponds to cortex, the critic net to the
thalamus, and the feedback loop to the reentrant connections connecting the two
brain centers.
Taking full advantage of IEI's SuperNets™,
robotic brains may autonomously knit themselves together to accomplish even more
complex tasks, such as navigating buildings or terrain, or how best to outsmart
an opponent system. Such self-organizing brains may effectively go to sleep and
rehearse their mission objectives within robotic
virtual reality simulations. To see a robot, starting from a state of no
learning whatsoever, and learning to walk, see IEI's tabula
rasa learning in robots.
