Using proprietary block co-polymer technology, directed self-assembly allows adding block co-polymers that assemble themselves into regular arrays on the surface of a silicon wafer that had been patterned using lithography.

Researchers in the UK and Japan use atomic force microscopy to visualize a DNA molecular robot moving along a 100-nm DNA track.
Here we present a special report from Dave Conz of ASU on Josh Hall’s talk and subsequent panel discussion at the SME nanotech conference. An excerpt: Technoscientific development is difficult to direct and nearly impossible to predict. Because of this – not in spite of it – panel discussions like “How Do We Get There [...]
PhysOrg.com brings news and a video of a new 3D patterning technique from IBM that reaches down to 15 nm resolution which “could go even smaller”: IBM Research in Zurich has demonstrated a new nanoscale patterning technique that could replace electron beam lithography (EBL). The demonstration carved a 1:5 billion scale three-dimensional model of the [...]
One of the species of early hominids is named Homo habilis, meaning “handy man,” after their significant advancement in tool use over previous hominids. One of the goals of the AGI Roadmap is to chart paths to full human intelligence, and one of the paths might follow the one that evolution took. The Wozniak Test, [...]
Foresight’s mission is essentially an educational one. In simplest terms we are here to point out foreseeable technological developments that not only will make the future different from the past, but make it different in ways that aren’t obvious and which everyone isn’t already planning for. Nanotechnology — true nanotech in Drexler’s original sense of [...]
Accelerating Future » RepRap “Mendel” to be Released Soon!. Nicw round-up with videos of the latest in the Rep-Rap world.
There’s an excellent round-up over at Next Big Future on the Roadmap for Additive Manufacturing. This is solid freeform fabrication, 3-D printing, stereolithography, rapid prototyping, and so forth. In the long run, 3-D printing is one of the more straightforward paths to full-fledged nanotech with mechanosynthesis. Mechanosynthesis might be seen simply as the ultimate in [...]
One of the major problems for micromachines, much less nanomachines, is wear. The phenomenon of stiction combines the two worst aspects of surface-to-surface interaction — a high coefficient of friction and a locally-generated high applied force — to cause enormous problems. At the very smallest scale, once we gain complete control over atomic configuration, superlubricity [...]
There’s a nice article over at the Singularity Hub that’s a round-up of currently-available haptics devices. They seem primarily excited over the prospects of haptics in gaming, but there are two reasons we’re interested in developments. First is simply telerobotics, as in Feynman Path manipulation. We want the feedback to help develop an intuitive feel [...]
Engineering and analysis in the field of SRMs is unusual in many ways. Eric Drexler has posted a paper about differences in evolutionary capacity in mechanical and biological systems that’s worth a look. Purely coincidentally, we at Foresight have been discussing self-replication in the context of the Feynman Path and I came up with an [...]
The CCC/CRA, a consortium of academic computer science departments (essentially), has a roadmap to future robotics that has some implications for the Feynman Path. Some highlights (from the chapter on manufacturing): Vignette 2: One-of-a-kind, discrete-part manufacture and assembly A small job shop with 5 employees primarily catering to orders from medical devices companies is approached [...]
Just Do It It’s the 20th anniversary of the first Foresight Conference this year. Over the intervening two decades, one of the most common questions of Foresight members and supporters has been, “What can I do to help with the development of nanotech?” Foresight has had many useful programs, and encouraged development in many ways [...]
Scaling KSRM Design Considerations There hasn’t been a lot of work on self-replicating workcells. There’s been plenty on robotic workcells that don’t replicate, but almost all of this falls into the “more complex than what it makes” category. The basic idea goes back to Waldo: imitate a machine shop and the person servicing the machines [...]
Where to Start? In the last post we suggested that finding the appropriate starting point was one of the critical items to address in forming a Feynman Path roadmap, and that is true. A thorough survey of available techniques should be made, and recent advances in machining, nanomanipulation, and so forth taken advantage of. However, [...]
Plan of Attack The difficult we do immediately. The impossible takes a little longer. (Seabees motto) There are at least two major parts to a project to implement the Feynman Path. The first is essentially to work out a roadmap for the second. In particular, Design a scalable, remotely-operated manufacturing and manipulation workstation capable of [...]
Open Questions Taking Feynman’s Path to nanotech, or even studying it seriously, would require finding answers to a number of open questions. These questions, however, are quite important and knowing the answers will be invaluable in understanding the envelope of possibilities for future manufacturing technology. Is it in fact possible to build a compact self-replicating [...]
Is it Worth Starting Now? Surely, you will say, it would have been wonderful if back in 1959 people had taken Feynman seriously and really tried the Feynman path: we’d have the full-fledged paraphernalia of real, live molecular machinery now, with everything ranging from nanofactories to cell-repair machines. After all, it’s been 50 years. The [...]
MEMS Another reason the Feynman Path may not have been tried is the perception that a machine-based approach has been tried in the form of MEMS, and that standard machine designs do not work at this scale and below due to stiction. MEMS are in fact crippled by this phenomenon, which is a essentially an [...]
Self-replicating Machines So why hasn’t the Feynman Path been attempted, or at least studied and analyzed? One possible reason is that there still seems to be a “giggle factor” associated with the notion of a compact, macroscale, self-replicating machine using standard fabrication and assembly techniques. Although studied in the abstract since von Neumann, and in [...]
