The CSA's Rex rover has a robotic arm that simulates collecting Martian rock and soil samples. It travels at 4cm/sec (1.57inch/sec). On its six aluminum or rubber wheels, the rover can navigate over obstacles up to 15cm (5.9 inches) high and climb slopes of up to 10 degrees. Rex weighs 140kg (308.64 pounds) and measures 152 x 142 x 76cm (59.84 x 55.9 x 29.92 inches). It can carry up to 30kg (66.13 pounds) of science payloads. In 2010, the CSA jointly field tested the rover with NASA at the Flagstaff Meteor Crater in Arizona. (Source: Canadian Space Agency)
These CSA rovers are a long way past "proof of concept." The concept(s) has(have) already been proven by Curiosity. These are correctly named prototypes, but they're not production prototypes, the type ervin007 apparently is thinking of; they're R&D/engineering prototypes, to test different designs and paths to achieving the same goals. CSA joint tests them with NASA, just like they did the Canadarms, and NASA has the means to put these on the moon, on Mars or in space.
The Dutch are known for their love of bicycling, and they’ve also long been early adopters of green-energy and smart-city technologies. So it seems fitting that a town in which painter Vincent van Gogh once lived has given him a very Dutch-like tribute -- a bike path lit by a special smart paint in the style of the artist's “Starry Night” painting.
For decades, engineers have worked to combat erosion by developing high-strength alloys, composites, and surface coatings. However, in a new paper, a team at Jilin University in China turned to one of the most deadly animals in the world for inspiration -- the yellow fat-backed scorpion.
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.
