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… Continue reading Feynman’s Path to Nanotech (part 9)

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… Continue reading Feynman's Path to Nanotech (part 7)

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… Continue reading Feynman’s Path to Nanotech (part 6)

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… Continue reading Feynman’s Path to Nanotech (part 4)

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… Continue reading Feynman’s Path to Nanotech (part 3)
