A prototype of a spacecraft planned as a 'lifeboat' for crews on the International Space Station passed a major milestone. The wingless X-38, the first new U.S. spacecraft developed in more than 20 years, successfully made its maiden unpiloted flight test. The nine-minute flight of the atmospheric test vehicle took place at NASA's Dryden Flight Research Center in California. The vehicle dove from the wing of a B-52 bomber at 23,000 ft. A series of parachutes slowed its descent. Then a 5,500-sq-ft parafoil--a steerable parachute--billowed out. The X-38 floated to a touchdown on its skids. The craft is the first of several increasingly detailed X-38s being built to test technology for a six-person "crew return vehicle." The X-38 has no engines. It uses the aerodynamic shape of the vehicle to provide the lift that airplanes get from their wings. In 2000, a space shuttle will carry a larger version of the X-38 into orbit. From there it is to plunge back to Earth for a practice landing.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
