NEXI - Robot with facial expressions
A latest invention by MIT Media Lab is a new robot that is able to show various facial expressions such as 'slanting its eyebrows in anger', or 'raise them in surprise', and show a wide assortment of facial expressions while communicating with people.
This latest achievement in the field of Robotics is named NEXI as it is framed as the next generation robots which is aimed for a range of applications for personal robots and human-robot teamwork.
DESIGNING
The head and face of NEXI were designed by Xitome Design which is a innovative designing and development company that specializes in robotic design and development. The expressive robotics started with a neck mechanism sporting 4 degrees of freedom (DoF) at the base, plus pan-tilt-yaw of the head itself. The mechanism has been constructed to time the movements so they mimic human speed. The face of NEXI has been specially designed to use gaze, eyebrows, eyelids and an articulate mandible which helps in expressing a wide range of different emotions.
The chassis of NEXI is also advanced. It has been developed by the Laboratory for Perceptual Robotics UMASS (University of Massachusetts), Amherst. This chassis is based on the uBot5 mobile manipulator. The mobile base can balance dynamically on two wheels. The arms of NEXI can pick up a weight of up to 10 pounds and the plastic covering of the chassis can detect any kind of human touch.
CYNTHIA BREAZEAL: HEAD OF THE PROJECT
This project was headed by Media Lab's Cynthia Breazeal, a well known robotics expert famous for earlier expressive robots such as Kismet. She is an Associate Professor of Media Arts and Sciences at the MIT. She named her new product as an MDS (mobile, dextrous, social) robot.
FEATURES OF NEXI
Except a wide range of facial expressions, Nexi has many other features. It has self-balancing wheels like the Segway transporter, to ultimately ride on. Currently it uses an additional set of supportive wheels to operate as a statically stable platform in its early stage of development. It has hands which can be used to manipulate objects, eyes (video cameras), ears (an array of microphones), and a 3-D infrared camera and laser rangefinder which support real-time tracking of objects, people and voices as well as indoor navigation.
Forget Windows: Midori is coming
WINDOWS is a name that has ruled the whole computer world since its first launch in November 1985. Since then it is like a trademark ofMicrosoft Corporation.
With many advanced versions of Windows available today such as Windows XP, Windows Vista, it is the most used operating system in the world. In 2010, Microsoft is going to launch WINDOWS 2007, but now here is time to experience a yet another technology of operating systems.
Yes, MICROSOFT is working on a new generation of operating systems called Cloud-Based Operating System and rumors are there that MIDORI will be their first such operating system, which will replace Windows fully from computer map.
WHAT'S THE DIFFERENCE
MIDORI is an offshoot of Microsoft Research's Singularity operating system. In this the tools and libraries are completely managed code. MIDORI is designed to run directly on native hardware (x86, x64 and ARM), will be hosted on the Windows Hyper-V hypervisor, or even be hosted by a Windows process.
MIDORI can be also seen as MICROSOFT'S answer those competitors who are applying "Virtualization" as a mean to solving issues within contemporary computing.
The main idea behind MIDORI is to develop a lightweight portable OS which can be mated easily to lots of various applications.
IMPORTANCE OF MIDORI
For knowing the importance of MIDORI you have to think about, how an operating system is loaded on a computer. Actually operating system is loaded onto a hard disk physically located on that machine. In this way, the operating system is tied very tightly to that hardware. As Windows is dependent on hardware, it might face opposition from contemporary ways of working because people are extremely mobile in using different devices in order get diverse information.
Due to this trend installing different applications on a single computer may led to different compatibility issues whenever the machine require updating. The new operating system will solve these problems by the concept of Virtualizing. This will solve problems such as widespread security vulnerabilities, unexpected interactions among different applications, failures caused by errant extensions, plug-ins, and drivers and many more
Vulture - Unmanned Aircraft
Defense Advanced Research Projects Agency (DARPA) of United States is working to develop an unmanned aircraft that is able to stay in air for a period of 5 years at a time. It is one of the most recent inventions of world.
Officials of DARPA has revealed that this aircraft will be known as VULTURE due to itsPersistent Pseudo-Satellite Capability . It means that this aircraft will be able to fly over a single area, communicating or performing analysis for years at a time.
Major Obstacles in Project:
Even this project looks appealing to many of you, but there are some serious problems or you can say obstacles in achieving this project.
1) First challenge in front of designers is to figure out some Way to Supply Power to this aircraft during long missions.
2) Another problem is that this aircraft will carry a 1000 pound (450 kg) payload in winds at an altitude of 60,000 to 90,000 feet.
3) Designers have also to sort out the problems regarding Deterioration of Materialsduring their long-time exposure to stratospheric flight.
In addition to this there may be many challenges during designing of this aircraft.
