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.
NASA's MAVEN spacecraft has entered Mars' atmosphere, carrying instruments to help Earthlings figure out what happened to it. Launched last November, the spacecraft arrived at the red planet right on time after a journey of 442 million miles.
Airbus Defence and Space has 3D printed titanium brackets for communications satellites. The redesigned, one-piece 3D-printed brackets have better thermal resistance than conventionally manufactured parts, can be produced faster, cost 20% less, and save about 1 kg of weight per satellite.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
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.
