Researchers invented a welding tool that also functions as a temperature sensor. The temperature is measured continuously and, if it becomes too hot, the heat is regulated by controlling the force and tool rotation. The researchers have also made use of an industrial robot to perform the welds and achieve a constant welding quality.
While civil aviation is on the threshold of potentially revolutionary changes with the emergence of increasingly autonomous unmanned aircraft, these new systems pose serious questions about how they will be safely and efficiently integrated into the existing civil aviation structure, says a new report from the National Research Council.
Engineers developed a simulation model that calculates the best trajectories for robots from the standpoint of energy efficiency. Tests have shown that this approach can reduce energy consumption by up to half.
Teamwork between humans and robots will be the motto of the future. But robots may not injure humans at all. When does contact cause an injury, though? Researchers are exploring this for the first time in a study.
With the increasing use of drones in military operations, it is perhaps only a matter of time before robots replace soldiers. Whether fully automated war is on the immediate horizon, one researcher says it's not too early to start examining the ethical issues that robot armies raise.
A recent study into the biomechanics of the necks of ants - a common insect that can amazingly lift objects many times heavier than its own body - might unlock one of nature?s little mysteries and, quite possibly, open the door to advancements in robotic engineering.
By designing assembly-line machines so they can perform on command - not unlike robots that can follow verbal instructions - factories can meet the rapidly changing needs of consumers and industrial customers, while developing high-quality products at lower costs.
Constructions that use not only digital but also analog compact and imprecise circuits are more suitable for building artificial nervous systems, rather than arrangements with only digital or precise but power-demanding analog electronic circuits.
