Removing the necessity of providing several different chemical fuels in a series of distinct steps, a novel chemically-fueled molecular motor autonomously produces movement as long as the fuel supply lasts.

Scaffolded DNA origami is combined with hinges of single- or double-stranded DNA to built simple machines parts that have been combined to program simple to complex motions.
Combinations of different types of DNA nanorobots, implementing different logic gates, work together to tag a specific type of cell in a living cockroach depending on the presence or absence of two protein signals.
Among the smallest molecular robots reported so far, a walker based on phenylarsonous acid with two organic thiol ligands as feet walks through a one-nanometer-diameter protein nanopore channel by taking 0.6 nanometer steps, by thiol exchange, from one cysteine residue to the next.
Nanotech promises more commonplace access to advanced technology as material and fabrication costs fall and traditional barriers to innovation are removed. Examples are already being seen globally: more access to laptops and cell phones in developing countries, desktop 3D printers, a surge in establishment of shared-use research facilities, etc. A couple recent cases getting attention [...]
With biotech fundamental to several paths to advanced nanotechnology, a way to do biotech experiments in the cloud offers small groups the chance to quickly test their ideas.
One research group working with rotaxanes and another group working with carbon nanotubes have provided two very different solutions to the problem of producing motion via artificial muscles at different scales from the nano to the macro.
A prototype humanoid robot being developed for the US military mimics a wide range of human movements while retaining its balance.
The Singularity University Executive Program recently took on the challenges of advanced nanotech: Nanotechnology: How should we evaluate the environmental impact of human-made machines that are too small to see? What limits should be placed on self-replicating nanodevices? What defenses should we institute against malevolent uses of such technology? These questions were asked by Marc [...]
In light of our continuing interest in the ways in which nanotechnology will interact with robotics and other emerging technologies, here is an update from IEEE Spectrum on the Boston Dynamics robot project. The earlier version called BigDog was cited here a few years ago, and was impressive enough. The update is a substantially improved [...]
Excellent lineup of speakers again this year for the Open Science Summit, Oct. 22-23, and you can get in for only $100 if you register by this Friday: http://opensciencesummit.com Hope to see you there! —Christine Peterson, President, Foresight Institute

Use code NANODOT for $50 off on: FORESIGHT@GOOGLE 25th Anniversary Conference Celebration & Reunion Weekend Google HQ in Mountain View, CA June 25-26, 2011 http://www.foresight.org/reunion Topics are emerging tech with special emphasis on transformative nanotech. A rockstar lineup of [...]
Willow Garage TurtleBot, an open source programmable robot with a 3D vision system, is available to preorder, starting at $500.
David Hanson of Hanson Robotics argues that building humanlike robots will push the boundaries of several scientific and technical disciplines and prevent intelligent machines from becoming dangerous as they achieve true general intelligence.
Robert A. Freitas Jr. has made available his chapter on nanorobotics from the book The Future of Aging.
Hogg and Freitas provide a theoretical analysis of the power constraints when nanorobots rely entirely on ambient bloodstream oxygen and glucose and identify aspects of nanorobot design that significantly affect available power.
The Space Studies Institute will hold Space Manufacturing 14 on Oct. 30-31, 2010 at NASA Ames here in Silicon Valley. Topics to be covered include: Session 1: Space Transportation Architecture Session 2: Closed Environment Life Support Systems Session 3: Robotics and Space Manufacturing Session 4: Extraterrestrial Prospecting Session 5: Engineering Materials from Non-Terrestrial Resources Session 6: Space [...]
Finishing off the week on a fun note, we see that robotic firm Willow Garage — of special interest to Foresight due to their emphasis on open source — has achieved an important milestone in robotics: namely, the ability for a robot to fetch a beer from the fridge and deliver it. It’s worth seeing [...]
If you can’t make it to Harvard this weekend, June 12-13, you’ll want to catch the live webcast of the H+ Summit: “Rise of the Citizen Scientist”. No link yet, but presumably they’ll be putting it on the event homepage before it starts. Also presumably they will post the videos somewhere for longer-term viewing. UPDATE: [...]
From Singularity Hub, 5 Axis Robot Carves Metal Like Butter: Industrial robots are getting precise enough that they’re less like dumb machines and more like automated sculptors producing artwork. Case in point: Daishin’s Seki5-axis mill. The Japanese company celebrated its 50th anniversary last year by using this machine to carve out a full scale motorcycle helmet [...]
