Three Respirocytes. As originally envisioned and designed by Robert Freitas, the Three Respirocytes of approximately standard design tumble in a clear suspension fluid prior to injection into the human body. Surface features are elevated to false height in order to emphasize the station layout and the dense-packing of molecular sorting rotors and molecular sensors on the respirocyte surface. | ||

Linked Vasculocytes. As originally envisioned and designed by Robert Freitas, the Two hexagonal vasculocytes, each measuring 2.7 microns in diameter, float in a clear suspension fluid. The two nanorobots are linked via docking ports in their adjacent metamorphic bumpers. Expansion or contraction of the bumpers allows the docked pair to vary their separation distance and thus to stationkeep over a periodically-stretching tissue surface such as an arterial vessel wall. Numerous mechanical legs providing locomotion, surface sensing, and other manipulation capabilities are visible beneath both units. | ||

Cell Rover. Just microns in length, the bio-engineered cell rover swims through the
human body performing useful medical tasks such as drug delivery, waste
product or toxin removal, cell targeting, intracellular transport and
cellular repair. This de novo protein device has a modular design
with an internal frame of keratin, chitin or calcium carbonate. Skin
panels are made of lipid bilayers to permit biomolecular inclusions such
as "self" molecules. There are one or more internal organelles for
mission-specific applications. Various propulsion schemes are possible,
including bacterial cilia, bacterial flagella, systolic means, pilin
harpoons and a novel external traction system utilizing kinesin or its
analogs, with power derived from natural in vivo resources. One method
of communicating (perhaps also supplying electric power) with its
onboard control system might utilize a deployable, submillimeter band
single-molecule radio antenna. The above device can be built without the
use of atomic assemblers. Biocompatibility requires engineering the
machine to appear as a native cell. |

Rotary Assembler. ""Rotary
Assembler" is on of my several robotic architectures,"
says Bishop. One of the machines
that will be possible using the new-found ability to manipulate single
molecules and atoms is illustrated here. This vaguely CD-ROM-like
machine assembles other nanomechanical systems by means of 5
degrees-of-freedom tips that pick molecules off the upper platter,
rotate down and deposit them on the product arrays of the lower platter.
