There are many different types of nanorobots .
Smallest engine ever created: “A group of physicists from the University of Mainz in Germany recently built the smallest engine ever created from just a single atom. Like any other engine, it converts heat energy into movement — but it does so on a smaller scale than ever seen before. The atom is trapped in a cone of electromagnetic energy and lasers are used to heat it up and cool it down, which causes the atom to move back and forth in the cone like an engine piston.”
3D-motion nanomachines from DNA: “Mechanical engineers at Ohio State University have designed and constructed complex nanoscale mechanical parts using ‘DNA origami’ — proving that the same basic design principles that apply to typical full-size machine parts can now also be applied to DNA — and can produce complex, controllable components for future nanorobots.
Nanoswimmers: “ETH Zurich and Technion researchers have developed an elastic “nanoswimmer” polypyrrole (Ppy) nanowire about 15 micrometers (millionths of a meter) long and 200 nanometers thick that can move through biological fluid environments at almost 15 micrometers per second…The nanoswimmers could be functionalized to deliver drugs and magnetically controlled to swim through the bloodstream to target cancer cells, for example.”
Ant-like nanoengine with 100x force per unit weight: “University of Cambridge researchers have developed a tiny engine capable of a force per unit-weight nearly 100 times higher than any motor or muscle. The new nano-engines could lead to nanorobots small enough to enter living cells to fight disease, the researchers say. Professor Jeremy Baumberg from the Cavendish Laboratory, who led the research, has named the devices ‘actuating nanotransducers’ (ANTs). ‘Like real ants, they produce large forces for their weight…’ ”
Sperm-inspired microrobots: “A team of researchers at the University of Twente (Netherlands) and German University in Cairo (Egypt) has developed sperm-inspired microrobots, which can be controlled by oscillating weak magnetic fields.” They will be used in complex micro-manipulation and targeted therapy tasks.
Bacteria-powered robots: “Drexel University engineers have developed a method for using electric fields to help microscopic bacteria-powered robots detect obstacles in their environment and navigate around them. Uses include delivering medication, manipulating stem cells to direct their growth, or building a microstructure, for example.”
Nanorockets: “Several groups of researchers have recently constructed a high-speed, remote-controlled nanoscale version of a rocket by combining nanoparticles with biological molecules…The researchers hope to develop the rocket so it can be used in any environment; for example, to deliver drugs to a target area of the body.”
