In a bid to crush those typically high robot-making costs, DARPA and its business partners (including iRobot) reckon they can now build high-end robot hands for under $3,000, down from what was once a $10,000 premium. According to The New York Times, the government, specifically the Pentagon, is looking to craft robot mitts that are able to detect improvised explosive devices by touch alone -- something that DARPA's worked on before. To demonstrate the progress it's made so far, the department's released a clip of one of its robots stripping a car tire -- you'll find it after the break. Now it just needs to figure out how to get it back on to the wheel.

Athens university prints polymer circuits with lasers, speeds us towards low-cost electronics
The dream of ubiquitous technology revolves around cheaper materials, and polymer circuits could help make the dream a reality... if the solvents used to produce the circuits didn't cause more problems than they cured, that is. The National Technical University of Athens has developed a more exacting technique that, like most good things in science, solves the crisis with lasers. The approach fires a laser at a polymer layer (covered by quartz) to throw some of that polymer on to a receiving layer; by moving the two layers, the scientists can print virtually any 2D circuit without resorting to potentially damaging chemicals. Any leftover worries center mostly around risks of changing the chemical composition as well as the usual need to develop a reliable form of mass production. Any long-term success with laser-printed polymers, however, could lead to more affordable technology as well as more instances of flexible and wearable gear -- there might not be much of a downside to ditching the circuit status quo.
