Stevan Harnad gave an
interesting keynote talk at the recent Julian Jaynes
Conference on Consciousness that both reminisces about Julian Jaynes
and addresses the question of whether consciousness depends more on
language or feeling. Harnad updates the classic question asked of Julian
Jaynes about whether or not is was alright to kick a dog if dogs were
not conscious. And what can we learn about consciousness from
speculating on the likelihood of Jaynes kicking dogs and robots? More
than you might think. Harnad's talk can be found in a newly released
paper titled, "What it Feels
Like to Hear Voices: Fond Memories of Julian Jaynes" (PDF format).

An
article
in Aviation Week states that last week, a MQ-9 Reaper UAV destroyed
a "vehicle carrying a remotely controlled explosive device in southeast
Iraq". Gizmodo
claims that this is "the first time in history" that two unmanned
systems "engaged and destroyed" each other. Other articles do not
go that far; they only state that this is the first combat engagement
for this particular UAV. The Reapers have reportedly have been in combat
in Iraq since
July 18 of this year, and in Afghanistan since last year. One
source says that "the Reaper costs about 80 percent less than a
manned fighter-bomber," "uses more than 90 percent less fuel, and can
stay in the air over a target three or four times longer than a jet
fighter". The smaller and less powerful MQ-1
Predator UAV is also being used in combat missions.

Traditional robotics applications such as CNC and welding have relied on
the idea that robots should be extremely rigid, with very precise
mechanics and encoders. This leads to robots that are very bad at
interacting with the real world. Animals, which are very good at
interacting with the real world, are full of wiggly, springy, imprecise
actuators. A new
paper (PDF format) from the CMU Robotics Institute looks at the
benefits of adopting this principle in robot leg design. Using
compliant, spring-like mechanisms, the robot can recycle energy and
exert higher mechanical power when walking or running. The researchers
examine a range of compliance using a variable stiffness leg, called the
Electric Cable Differential
(ECD) Leg.

With the goal of inspiring and educating young robot builders everywhere,
kidbots.com's mission is to show
how millions
of old, obsolete computers can be turned into
programmable robots. Included is a brief introduction to
electronic components, PC components, CPU operation, and programming.
Special attention is paid to use of the PC's parallel printer port as
general
purpose I/O to control actuators and read digital sensors,
along with simple code examples in BASIC.
The site is summed up with a fun animated gif
showing a tin-can robot
walking across a pile of old motherboards.

Using micro-claws or sticky material (depending on the task at hand),
RiSE can climb up trees, fences and vertical walls with help from his
surface-conforming body and rigid tail.
Video of RiSE at Boston
Dynamics' website shows off his capabities.
RiSE is 25cm long, weighs to 2 kg and uses 2 motors per leg.
Sensors include inertial measuring, joint positions,
strain and foot contact. Boston Dynamics is working
on future versions using dry adhesion to tackle vertical
climbing on glass and other slick surfaces.

Howard Gordon writes, "Robot remote control via Internet is not a new
concept, but this demo,
created by Ogilvy New Zealand for BP Australia takes things to a new
level." You can find more info about the project in the Surveyor
news blog. Another reader pointed us to an interesting PLoS
Biology paper that discusses some interesting parallels between
language evolution and biological evolution including evidence of
punctuated (no pun intended) equilibrium. The Swirling Brain pointed out
a Technology
review story on a new MRI technique called Diffusion spectrum
imaging (DSI) which is revealing new information about the organization of
brain cells. He also noticed stories on an artificially
intelligent glider, a Scientific
American report about a clever psychological experiment on free
will, new
spoilers about Terminator Salvation revealing a religious "building
robots is a sin" theme, and an article on
the winners of the UK
MoD Grand Challenge. Roland Piquepaille's latest blog post is about
an AUV being used to explore the world's deepest underwater volcanoes in
the Caribbean. Know any other robot news, gossip, or amazing facts we
should report? Send 'em our way

Without soldering, welding or gluing, Jeremy Mayer re-invents
mechanical typewriters into fantastic works of
living-system-inspired art.
The result is a mechanotronic style distinct from the iron-oxide-encrusted
SteamPunk genera, sporting cleaner lines and a more natural look.
Jeremy's creations include full-scale, anatomically correct humanoid
figures as well as 4-legged beasts.

In the latest episode of the Robots podcast we talk about two
major events in aerial robotics this summer. First, Christophe
de Wagter, who is one of the main developers of the DelFly flapping
wing robots, gives us an insight into the latest and smallest member of
the DelFly family: The DelFly Micro, a
3-gram robotic dragonfly announced a couple of weeks ago. In a second
interview Peter
Vörsmann, the chair of this year's European Micro Air Vehicle
Competition (EMAV'08), takes us
through the latest advances in autonomous flying vehicles. More infos,
including recent videos, on the Robots
page.

It's been a while since we've seen a Rodney Brooks interview,
so we thought you'd enjoy reading Newsweek's recent
interview. He talks about the importance of gaze direction in making
robots socially interact with humans. He answers the question of what
the most interesting robots are that he's seen lately. He talks about the
Uncanny Valley and human-looking robots. He says that the popular
conception of robots as different from humans is an artificial
distinction since we're both machines, just of different types. But he
notes, "Whether we humans are smart enough to build such machines is
a different question. Maybe we're just not smart enough. That pisses off
the scientists when I say that.".

Photos are popping
up
in blogs
all
over
the
net of a
shiny, silver Cyberdyne Systems Terminator skull. It has a white teeth,
glowing red eyes, and a DVD player that's revealed by opening up the top
of the skull. Yes, that's right, the endoskeletal skull of a killer
robot that plays DVDs in its head. These things appear to originate in
Asia but no one has been able to identify the manufacturer or exact cost
yet. There are more
angles
and close up photos
around if you look for 'em.

Via
Craftzine, we noticed a B-Side blog report on the most
amazing R2-D2 cake ever (actually, it's red so I don't think it's an
R2-D2, maybe an R2-D1 or something?). Anyway, as edible astromechs go,
this one is pretty cool. The body is made of many levels of red velvet
cake while the legs were cut from giant Rice Krispy treat blocks. Once
assembled, the whole thing is coated with white, red, and silver icing
and all the expected details are added. There's a nice photo sequence of
the R2
cake being assembled and of the actual presentation
at a kiddo's birthday party. The cake was made by Mark Joesph Cakes in
Brooklyn, New York.

Ed Okerson was the
first of many robots.net readers who sent links
to a NewScientist story about the rat-brained robot from the
Univserity of Reading. Instead of the usual silicon-based embedded
controller, this robot sports a carbon-based unit made up of 300,000 rat
brain neurons. The mini-brain lives in a jar of nutrients and
antibiotics. A multi-electrode array (MEA) feeds sensor information into
the brain and
transports control signals out of the brain to the motors. Unfortunately,
the brain is growing so bored that it's exhibiting bursts of
seizure-like activity. "Like a creature with no limbs or senses, the
cut-down brain is simply bursting out of boredom". While the rat
brain may not be enjoying life much, the scientists are having a blast
and suggest the research may help them understand Alzheimer's,
Parkinson's, epilepsy,
and other diseases caused by malfunctioning neurons. For more, see the
BBC story
and video, the Slashdot
discussion, or original University
of Reading press release. Update: Roland Piquepaille just posted about this robot as well.

According to a new Telegraph
UK article, "a deep mathematical analysis of living things has
come up with an insight into why they are special". The research was
done by a researchers at Edinburgh University and the Max Planck
Institute for Mathematics in the Sciences. What they've discovered is a
way to make the behavior of artificial and virtual creatures self
organizing and self regulating, allowing them to learn through trial and
error without explicit instructions. The idea is not new and
follows similar research going back to 1990. The article includes
video of virtual dogs learning to jump and virtual humanoid learning to
stand. Previous systems had explicitly encoded goals in the programs as
well as basic instruction on how to move. The new algorithm, called
homeokinesis, has no
predefined goals, and provides no initial information about the virtual
environment, making it more like the natural world. The researchers are
also beginning to experiment with the algorithm in real
robots. For more videos and papers on the new system, see Terra
autonomica - The world of self-organized creatures.

We're all familiar with personal space; the invisible bubble that
encompasses our mental image of our body. Personal space expands to
encompass tools (even cars) that we mentally incorporate as part of our
body and may also change size according to our mood. We're less
conscious of Peripersonal space; an invisible bubble that represents
localized reaching distance. Any object in our peripersonal space can be
reached or
manipulated directly. Objects outside our peripersonal space require us
to move toward them before they can be manipulated. There has been some
debate as to how our brains determine the boundry of peripersonal space.
A new
paper (PDF format) suggests the brain doesn't determine the
peripersonal space boundry purely by vision but with the help of
feedback from the motor representation areas of the brain. Robots must
solve these same problems and understanding how the human brain does it
should give roboticists something new to think about.

Time for another weekly dump of stories from the editor mailbox. This week
Davide Faconti of
Pal Technology Robotics
writes, "You have already written a story about us. Our
team needs to grow in the next month: we need about 8 people joining
forces with us to develop the best possible humanoid robot (better than
Asimo, hopefully!!!)." So if you've been looking for a chance to
work on one of the most advanced humanoid robot projects in the world, here it is. Davide
also sent us a YouTube video of
REEM-B appearing in front of the crown prince in Abu Dhabi. Mark
Miller, aka the Android Man, sent a photo
of his latest robot art creation. VIA announced
the appointment of Harald Welte as their
Open Source liaison. This is good news as it means VIA will be freeing
more of their driver code and hardware specs, making life easier for
hardware hackers like us. The Swirling
Brain wants us to know about The
Death of HAL. Roschler sent us links to
his Femisapien
review and a YouTube Wall-E
video. Roland Piquepaille posted in his blog
about a project to teach language to robots. And, finally, Trossen
Robotics announced
their new Robobuilder robot kits.

It's New Year's eve 2026.
Will the robot overlords even notice you're missing?
Or will they simply clean around your decayed remains following
a preprogrammed script of daily duties?
Will swallows penetrate the faux window?
Will Jesus get revenge for unnecessary impalation?
These questions and more are asked by
the animated Soviet version of Ray Bradbury's short story
"There Will Come Soft Rains".

A Telegraph.co.uk article, Can
we make software that comes to life? covers the debate among
biologists, computer scientists, physicists, mathematicians,
philosophers and social scientists who have gathered in Winchester
to discuss artificial life. After more than a decade of work,
researchers think they've hit a barrier with what can be done with
evolution within a software environment. The scientists think the
problem is the lack the self-organizing principles in software that are
part of the physical and chemical world where biological evolution
occurs. The article
notes that this self organization can be seen in something as simple as
a saucer of oil that's heated. What's needed is a better understanding how
self organization integrates with natural selection. The article also
covers other aspects of artificial life research including both "wet"
ALife (artificial biological life) and "in silico" ALife (software based
life).

Emanuel Diamant has written a paper that will be published as a chapter
in a forthcoming book, "Frontiers in Brain, Vision and AI". His paper
has the provocative title, "I'm sorry to say, but your
understanding of image processing fundamentals is absolutely wrong"
(PDF format). Diamant observes that the biggest argument about machine
vision is whether we should be working on visually-enabled cognitive
systems or cognitively-enabled vision systems. He says this argument is
groundless because "perceptual and cognitive faculties of vision are
separate components of human (and consequently, artificial) information
processing systems". Whether you're interest in robot vision or
human vision, this is an interesting read. For more of Diamant's idea on
vision, see the list of previous
papers available on his website.

Here's another load of interesting robot stories from the editor's
mailbox. Tom Benson of Readybots writes, "Just wanted to send you our
latest announcement
(and video) of
Readybot". Readybot is a kitchen cleaning bot that we've mention
before. Robosoft sent us this news, "ROBOSOFT announces the delivery
of three VolcanBuls to Vulcania. These vehicles, without a driver
and guided exclusively by GPS, take visitors on a 1km tour through the
park to observe the Puy volcanic mountains and to learn about their
history." Robots and volcanoes in one places. What more could you
want? Michael Somby writes, "I wrote an article
discussing software packages available for service robotics
applications". The Swirling Brain sent links to a story about robot
snowmobiles that help scientists study the melting ice in the
Antarctic, a list of the 7
creepiest robots ever, a GEARlog
story about Care-O-Bot 3, an io9 report
(with photos) on the Pittsburgh Robot 250
Festival that we reported on a while back. He also noticed a cool Wired photo
gallery of wooden steampunk robot art by Michael T. Rea, and another of the Vstone
Blackbox robot. Oh, and for Battlestar Galactica fans, he spotted a
trailer
for the new Caprica series. The latest from Roland Piquepaille
includes a story on the DelFly autonomous air
vehicle, a wire-bending dental
robot that will make you smile, and a robot buoy to track oil
spills. Know any other robot news, gossip, or amazing facts we
should report? Send 'em our way please.
