If the current research of Dr. Ashutosh Saxena of Cornell’s Personal Robotics Laboratory becomes successful then Robots of future will learn to manipulate objects and will develop the ability of generalization. This learning procedure will help Robots to adapt according to new environments.

The main theory behind this is the use of machine learning programming which leads to observation of events by Robots and find commonalities. For an example a robot will see different cups, learn the common characteristics of cups and will then identify cups in future no matter what size and shape they will have. This kind of process will also teach robots to handle cups correctly.

According to Saxsena, these new robots would be able to make decisions like how to place cups on different places. Like a cup will be placed upright on table while upside down in dishwasher. Robots will get training of placing strategies and will be able to apply then on other objects by the process of generalization.

In testing process scientists placed different things like a plate, mug, glass, bowl, spoon and some other objects at different surfaces like on flat surface, hook, stemware holder etc. Robots then tested the suitable locations for placement of these objects after studying the environment and gave priority to best locations to place an object.

After such training Robot placed objects 98% correct at previously seen environment and objects. This accuracy was 95% for new objects and environments and that can be improved further by longer periods of training.

The base of all this is the contextual relations in 3-Dimensions.

Although making a Robot that acts just like humans will take long time but by making Robots like these is a giant leap in Robotics.

The newly launched Russian satellite Express AM-4 which was known as the most powerful satellite ever built in Europe has lost track with Russian space agency. This satellite was launched recently from Kazakhstan where Russia has a leased launch pad.

According to space scientist related with this mission said that the cause of communication lost was the failure of Briz-M upper stage. Experts are trying to re-establish the connection with the craft, however according to officials there are only 75% chances of re-establishing the contact back with craft.

The spacecraft is insured for $264.5 million with premier insurance company of Russia, Ingosstrakh.

This failure is a hard blow on Russian space industry and can delay many important projects by 3 to 4 years. Earlier this year, Russia space agency have faced unsuccessful launch of three orbiters which resulted in a loss of $160 million after these orbiters crashed in Pacific Ocean.

quantum computers Scientist has got success in linking the quantum properties of two separated ions using microwaves to manipulate them. This is currently done with the help of laser beams and now this advancement can shrink the size of quantum computers. This research has been done at NIST (National Institute of Standards and Technology) which has been published in Nature.

Microwaves have been used previously in manipulating single ions, but this is the first time when scientist from NIST used this on two separated ions places just 30 micrometers away. This kind of process give rise to a quantum mechanism which is crucial for information transportation and error correction in Quantum computers.

The mentioned experiment use desktop scale table of lasers and very small mirrors and lenses that are around 1/10 th of the sizes that are actually used these days. Microwave components can be easily expanded to make a practical quantum computer system. Also by using microwaves they were able to reduce errors that are however caused by using laser beams due to incorrect pointing issues and power.

Scientist Dietrich Leibfried said that it may be possible to have a quantum computer of a size of smart phone in near future. More powerful quantum computer can be made up to a size of Desktop PC.

nanodiamond circuits Scientists at Vanderbilt University have developed computer chips and circuits made up of Diamond film to make them more venerable than their silicon counterparts. Transistors and Logic gates of Diamond have already been developed and they are now working to create complete microelectronic devices with diamond parts. Such devices can operate at higher speed and need less power than silicon made devices.

In journal Electronics Letters, the design of such diamond logic gates have been described. Research Professor and head of team, Jimmy Davidson said that devices using diamond parts will not be expensive as 1 carat of diamond can be fabricated to make around 1 billion such devices. Diamond films used to create these devices are made up chemical vapor deposition technique that uses hydrogen and methane. This form of diamond is much cheaper than conventional diamond used in jewelry. This makes them economical and a tough competitor to silicon parts.

Nanodiamond circuits use technologies of old fashioned vacuum tubes as well as solid state microelectronics. A thin film of diamond is laid down on silicon oxide layer. This facilitates movement of electrons through vacuum between nanodiamond components. This reduces the problem of heating up of normal microelectronics devices as in these types of devices a vacuum movement of electron occurs. Also diamond being the best electron emitter needs much less energy to produce electron beams, which in turn reduced the electricity consumption to operate these devices.

Another major advantage of nanodiamond devices is that such devices are immune to radiation damage which causes the tripping of circuits in normal electronics devices. As electrons moves in vacuum in nanodiamond devices, there are no energetic particles to disrupt.

So you can easily imagine the benefits of such nanodiamond devices.

Co-CEO of Motorola, Mr. Sanjay Jha announced this new mobile in San Francisco at Mobilize 09 conference. Motorola Cliq will be available with T-Mobile by the end of next month. Initially it will be launched by T-Mobiles in titanium and winter white colors. Motorola planned to sell it throughout the world from 2010 as “The Motorola Dext”.motorola-cliq

Price:

The price of Motorola Cliq has not been revealed till now, but it is rumored that it will be a budget phone. Motorola is also going to announce its second Android Phone soon as said by officials.

Specifications:

Measurements of Cliq mobile by Motorola are 4.49 inches tall, 2.28 inches wide and 0.62 inches thick. It weighs 5.6 ounces that is around 158 grams. It features a 3.1 inch HVGA touch screen with 320×480 pixel resolution. It has a slide-out QWERTY keyboard and a soft keyboard as well. It also has a 3.5 mm headphone jack.

Operating System and Features:

Motorola Cliq will run Android 1.5 cupcake and you can access to various services by Google which includes Google Maps with street view, voice search by Google, Picasa and Google Talk. This mobile phone supports various e-mail clients such as Windows Live, Yahoo and many other POP3 and IMAP services. You can also use Quick Office suite to view documents.

Motorola Google android Phone

Cliq is a 3-G phone which offers full HTML Google browser, Wi-Fi, Bluetooth and GPS facilities. With its 5-megapizxel camera you can capture images or can record videos. It is also equipped with built-in music and video player.

It will come preloaded with Amazon MP3 store, You Tube App, Shazam, Last.fm and Immem. Talk time is 6 hours while standby time is upto 13.5 days.

Motoblur User Interface:

Motorola Cliq will be equipped with Motoblur user interface which will differentiate it from other smartphones available these days. Motoblur interface will sync information from sources such as Facebook, Twitter, MySpace and Gmail accounts. This will save your time in opening and closing these applications.
