Year end review of “neuromorphic” chip prototypes

http://www.technologyreview.com/featuredstory/522476/thinking-in-silicon/ MIT Technology Review today features an overview of processors that they claim are “about to narrow the gulf between artificial and natural computation—between circuits that crunch through logical operations at blistering speed and a mechanism honed by evolution to process and act on sensory input from the real world.” Caltech’s Carver Mead pioneered “brain […]

Nerve interface simulates touch in prosthetic hand

http://www.technologyreview.com/news/522086/an-artificial-hand-with-real-feelings/ Cleveland Veterans Affairs Medical Center and Case Western Reserve University researchers have developed an interface that can convey a sense of touch from 20 spots on a prosthetic hand. It directly stimulates nerve bundles, known as peripheral nerves, in the arms of patients.   Two people have been fitted with the interface to date. […]

IBM unveils prototype of “brain-inspired” computer

http://www.bbc.co.uk/news/science-environment-24571219 The human brain is 10,000 times more dense and efficient than any computer today. IBM is using the brain as a design template, including using fluids to cool the machine and distribute electrical power. This could enable processing power that is densely packed into 3D volumes rather than spread out across flat 2D circuit boards […]

Crowdfunded, tendon driven robot mimics human movement

http://www.roboy.org/about.html Univerity of Zurich’s AI Lab has crowdfunded its first version of an open source, flexible robot. Roboy, developed by Professor Rolf Pfeifer, has a four foot tall human shape and a set of “muscles” inspired by the human musculoskeletal system. The plastic muscles work together via electrical motors and artificial tendons. Its tendon-driven systems mimic […]

Personalized robot companion for seniors

http://cordis.europa.eu/fetch?CALLER=OFFR_TM_EN&ACTION=D&RCN=11525 A European consortium of research institutes, universities and technology companies has developed a highly customizable robot companion to help seniors to maintain their quality of life, stay healthy and avoid social exclusion. The robot, a mobile wheeled semi-humanoid figure equipped with cameras, sensors, audio, and a touch screen interface, can remind users to take their […]

Neuromorphic chip mimics human brain in real time

http://www.mediadesk.uzh.ch/articles/2013/chips-die-das-gehirn-imitieren_en.html University of Zurich and ETH Zurich scientists have created a two by two millimeter microchip with 11,011 electrodes that mimics the brain’s processing power.   The brain-like microchips are not sentient beings, but can carry out complex sensorimoter tasks in real time.  Previous brain-like computer systems have been slower and larger.  This system, developed by Professor […]

Algorithm analyzes head movements to measure heart rate

http://web.mit.edu/newsoffice/2013/seeing-the-human-pulse-0620.html MIT researchers have developed an algorithm that gauges heart rate by measuring tiny head movements in video data.  A subject’s heart rate was consistently measured within a few beats per minute when compared to results from electrocardiograms. The algorithm was also able to provide estimates of time intervals between beats, which can be used to identify […]

Low cost GPU based neural network simulates the brain

http://stanford.edu/~acoates/papers/CoatesHuvalWangWuNgCatanzaro_icml2013.pdf In a new paper, Stanford’s Andrew Ng describes how to use graphics microprocessors to build a $20,000 computerized brain that is similar to the cat-detector he developed with Google last year for $1M. To test his hypothesis about GPU-driven Deep Learning, he also built a larger version of the platform for $100,000.  It utilized […]

Nerve and muscle interfaces for prosthetic control

http://www.darpa.mil/NewsEvents/Releases/2013/05/30.aspx DARPA continues to build technology with academic partners to enable amputees to control prosthetic limbs with their minds.  Examples follow: Researchers at the Rehabilitation Institute of Chicago demonstrated a type of peripheral interface called targeted muscle re-innervation (TMR). By rewiring nerves from amputated limbs, new interfaces allow for prosthetic control with existing muscles. Researchers […]

Cornell robots anticipate human actions

http://news.cornell.edu/stories/2013/04/think-ahead-robots-anticipate-human-actions Cornell University researchers have programmed a PR-2 robot to not only carry out everyday tasks, but to anticipate human behavior and adjust its actions. From a database of 120 3-D videos of people performing common household activities, the robot has been trained to identify human activities by tracking the movements of the body – reduced […]
