swarms

Robot swarms could someday hover, spin, and attack in response to a simple gesture or graceful pirouette from a human operator. And yes, Boeing has filed a patent on that future vision.

"The method may involve defining a plurality of body movements of an operator that correspond to a plurality of operating commands for the unmanned object," Boeing notes in its patent filing. "Body movements of the operator may be sensed to generate the operating commands."

Hoping that many hands will make lighter work, German energy company Lichtblick has teamed up with Volkswagen on a project to install 100,000 miniature gas power plants in people's homes over the next year.

According to the companies, using more, smaller plants, instead of fewer, larger plants, will allow Germany to move away from nuclear power, and reduce carbon emissions by 60 percent. Together, the 100,000 mini-plants would produce 2,000 megawatts, or as much as two nuclear power plants.

While Hollywood focuses on robots several times taller than humans, some researchers are building tiny robots that could fit on your fingernail. These microbots would work in swarms to collect data for a variety of applications, such as surveillance, micromanufacturing, and medicine.

The researchers, from institutes in Sweden, Spain, Germany, Italy, and Switzerland, use a novel approach to allow robots to be built cheaply and in large quantities. Working on a limited budget, they built an entire robot on a single circuit board.
