Liquid Robotics' new Wave Glider robot, the SV3 (right, in red) is bigger than its predecessor, SV2 (left, in yellow), shown during sea trials in Hawaii. The SV3 uses stored solar energy for part of its propulsion system, combined with the Wave Glider's unique, wave-powered energy harvesting system. (Source: Liquid Robotics)
Ann, this is a remarkable integration of a number of technologies -- solar, battery, energy storage, conversion of ocean movement. If you gather a number of technologies together no sngle technology has to be perfect. This is a good example.
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
A tiny humanoid robot has safely piloted a small plane all the way from cold start to takeoff, landing and coming to a full stop on the plane's designated runway. Yes, it happened in a pilot training simulation -- but the research team isn't far away from doing it in the real world.
Some in the US have welcomed 3D printing for boosting local economies and bringing some offshored manufacturing back onshore. Meanwhile, China is wielding its power of numbers, and its very different relationships between government, education, and industry, to kickstart a homegrown industry.
You can find out practically everything you need to know about engineering plastics as alternatives to other materials at the 2014 IAPD Plastics Expo. Admission is free for engineers, designers, specifiers, and OEMs, as well as students and faculty.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
