shop

2008-05-07T23:40:00.000-07:00

Everyone likes shopping. If there is dvd player in their own car. Then it is awesome. Entertainment is the best part in everyone's life. So, for that purpose everyone wants to do shopping and roaming in searching of what they want actually. As it is usual, if a person in need of something, he/she will crawl into the site. The site which i am going to tell will have lot of information on every product. This could be done by just watching that site.

The loud speakers, steroes and something else, if you want to buy those in your own budget, then buying from that site is the correct way. There are many dvd players offered from that site. Some of them like portable dvd players, ceiling mount dvd players and some of the cool gadgets some thing like In-Dash Receivers, Headrest Style Monitors and so many things. If you have any doubts, just contact them . They will reply you soon.

10,000BC

2008-03-14T01:16:00.000-07:00

As of now, i heard the newly released movie which is 10,000BC was a worst movie. My friends and the content on other blogs about this movie was quite bad. They don't want to rate this movie too high. Just an average movie because of little thrilling at later stages of a movie. There is no coherence with this movie and actual story which was written in books. It was highly animated movie and very less about the real shooted scenes. When compared to other movies like Jurassic park and tomorrow never dies, this was not that much good. Whatever it may be, i will go to one good theater and see this movie. After watching that, again i will be back and talk about this movie.

My interview

2008-03-08T21:47:00.000-08:00

Guys, my interview went well but i think results were sucks. Out of 13 , in a aptitude round they selected 4 for personal interview. In that 4 i am one among of them. For all of us interview went in a same wavelength, i mean same type of questions. From those questions, i don't know what they concluded from that. They tested my attitude and technical stuff. Almost i did well, may be for 1 or 2 questions i might committed mistakes. They are very jovial and cracking jokes along with me. It seems that interview was not so serious. They even ask about my blogging and my earnings. But i did not give relevant information about that. Just playing around that question, and at the end when i about to leave , my HR gave comments on my blogging. After finishing interview for 4 of us, they did not reveal the results. Instead, they told that it will reach to respective colleges. Let's hope for the best and pray to god for me.

Anna univ

2008-03-07T05:55:00.000-08:00

I wanna talk about anna university paper evaluation. Their evaluation is sucking. They will never look into the content as what the student has written. Even i am experienced their evaluation. It is a kind of irritating one. They make me to fail in two subjects because of that i lost distinction. Right now my aggregate is 76%... But what is the use of keeping that much percentage. I will never get distinction even after crossing that percentage at the end of my 4 years of engineering. Anywayz like me there are so many students who were depressed about anna university correction.

Cricket

2008-03-05T21:17:00.000-08:00

I am big fan about playing cricket. Because i know only that game to play well (lol). Though India national game is hockey, but everyone look only cricket in a positive look. It makes that india national game is cricket and not as hockey. It seems to be shame for indians because the sponsors for hockey also is very less. So, everyone should think about it, try to change that system and let us encourage our national game. Let's do it as soon as possible.

weird blogging

2008-03-05T21:09:00.000-08:00

hey, you know around millions of people were crazy about blogging. For some people, it became primary making money for them. All wives of different countries started this blogging for time pass. But right now it became primary source for them to earn lot of cash. For part time job holders, they will feel this is great opportunity for them to earn minimum amount of money. Daily, atleast you can earn about 5$, but you need to be before the system for long time. Only that, you can grab some task. And one more thing is, if your site has good page rank and alexa rank, you can earn millions within 6 months of time. It looks great know...yes, it may look great but once if you started that, you will feel it is true. So, all the best wishes to upcoming blog holders.

Mam class

2008-03-05T20:58:00.000-08:00

hmmm...now i am going to tell about the class, especially robotics class, where my mam has taken it. Oh.. my god i did not understood that class even a single concept. i got bored of that class completely, initially i am having lot of interest regarding robotics and robots. Even i did some case studies regarding that. I, myself did some self study and even took seminars on that topic. My friends know me very well that i had lot of interest on robotics. With my self study, i feel that robotics is a very good topic to specialize. But, then my mom took that class in an uninteresting way. I am hating that concept right now. Anyways, i will create again my interest on that and come back with good temptation.

Multi-tasking

2008-02-27T22:14:00.001-08:00

There is great news for lovers of robotics, multi-tasking robots are going to come to markets. These multi-tasking robots will all types of works at a time. In movies, we usually see such type of robots doing all kinds of works. These multi-tasking robots can clean our homes, cook the food, clean the utensils and lots more. So, now we need not worry about keeping servants for large salary in our houses. This is the best thing getting a multi-tasking robot. They are cost-effective ad easily re-configure if we face any problems with that. Generation to generation there is tremendous change in human working behavior. They are decreasing their physical work and increasing their mental work. If we have more mental work then there is chances of facing more number of diseases. So, think about it and start increasing your physical work.

Water

2008-02-27T22:06:00.000-08:00

Now i am going to tell about the importance of water. Water is a chief component on earth where everyone should depend on it. For cleaning our ass also sometimes water is needed. For examining whether life is existing on terrestrial planets also, scientists need water traces. Though our earth is covered 3/4th of water, most of the water is not useful for humans. Only the water from polar ice caps is consumable and good for humans. So, humans are doing experiments on non-usable water resources and trying to convert that into good water. Most of their experiments are quite successful and they are looking for cost effective. Because treatment of such water is a difficult process and needs great amount to set-up such treatment plants. So, here also cost is playing major role. Let us hope for the good and cheap price of those plants.

Robomation

2008-02-27T21:59:00.000-08:00

Hi, confuse on seeing my post heading..? it is simple, combination of robot by the automation work is called as Robomation. Recently, scientists are working with the robots to do automation work. They were almost succeeded in doing that. It has shown better results and soon they are going to introduce those things into the market. There are so many great advantages by this Robomation, generally humans should be there at control center to see automation process, right now we can replace humans with the robots. They will see the automation work and if we need any changes to make it then robots will change it. It a new era in this latest technology. Coming to cost, it may be more than what industrialist are expecting. The cost is quite high because of highly intelligent robots.

Gonna hit bull's eye

2008-02-16T04:19:00.000-08:00

Buddies, i think in this i am going to get page rank for my awarenessforu blog, because i did lot of link exchanges and submission of my blog to many directories. Actually its my target to get page rank after three months of blog started date. Soon i am gonna reach that. When it get's page rank, again i will write special post regarding that. First i thought that it will be very easy to get higher page rank but indeed it's not the actual fact. It will be very difficult to get indexed in the top rank search engines. For that you need to have quality blog and the content should not copied from external source, if you do that then it will be very difficult for you to get indexed in search engines. They will be having one special software where they will check your content whether it was copied or not. Initially when i started this blogging, i dont know properly about html language also. Some of my widgets were not get correctly attached to my site, and some widgets will be in disorder. But soon i realize the power of html language and i started taking care about my site design.......

Robotics

2008-01-26T05:31:00.000-08:00

Robotics is the science and technology of robots, their design, manufacture, and application. Robotics requires a working knowledge of electronics, mechanics and software, and is usually accompanied by a large working knowledge of many subjects. A person working in the field is a roboticist.

Although the appearance and capabilities of robots vary vastly, all robots share the features of a mechanical, movable structure under some form of autonomous control. The structure of a robot is usually mostly mechanical and can be called a kinematic chain (its functionality being akin to the skeleton of the human body). The chain is formed of links (its bones), actuators (its muscles) and joints which can allow one or more degrees of freedom. Most contemporary robots use open serial chains in which each link connects the one before to the one after it. These robots are called serial robots and often resemble the human arm. Some robots, such as the Stewart platform, use closed parallel kinematic chains. Other structures, such as those that mimic the mechanical structure of humans, various animals and insects, are comparatively rare. However, the development and use of such structures in robots is an active area of research (e.g. biomechanics). Robots used as manipulators have an end effector mounted on the last link. This end effector can be anything from a welding device to a mechanical hand used to manipulate the environment.

Stepper motor

2008-01-20T05:28:00.000-08:00

Stepper motors operate much differently from normal DC motors, which rotate when voltage is applied to their terminals. Stepper motors, on the other hand, effectively have multiple "toothed" electromagnets arranged around a central gear-shaped piece of iron. The electromagnets are energized by an external control circuit, such as a microcontroller. To make the motor shaft turn, first one electromagnet is given power, which makes the gear's teeth magnetically attracted to the electromagnet's teeth. When the gear's teeth are thus aligned to the first electromagnet, they are slightly offset from the next electromagnet. So when the next electromagnet is turned on and the first is turned off, the gear rotates slightly to align with the next one, and from there the process is repeated. Each of those slight rotations is called a "step." In that way, the motor can be turned a precise angle. There are two basic arrangements for the electromagnetic coils: bipolar and unipolar.

Stepper motors are constant-power devices (power = angular velocity x torque). As motor speed increases, torque decreases. The torque curve may be extended by using current limiting drivers and increasing the driving voltage.

Steppers exhibit more vibration than other motor types, as the discrete step tends to snap the rotor from one position to another. This vibration can become very bad at some speeds and can cause the motor to lose torque. The effect can be mitigated by accelerating quickly through the problem speed range, physically dampening the system, or using a micro-stepping driver. Motors with greater number of phases also exhibit smoother operation than those with fewer phases.

India roars

2008-01-18T06:15:00.001-08:00

The third test match which is going between India and Australia ,shows some better performance from Indian side. Though the couple of wickets have fallen early in the morning, they keep total to be running for their target total. Sehwag turned into this 3rd test match and his performance was quite satisfactory. First innings he scored 29 runs and second innings score 43 runs. It's a good come back after long time. Then irfan pathan who came as night watchman has stood long innnings and able to score 46 runs which aremore important runs.Now laxman and dhoni were batting beautifully and laxman had magnificiant 50 in this innings.

Anywayz letz see who will win the match ............hope for the best.....

sensors

2008-01-15T05:27:00.000-08:00

A sensor is a type of transducer which uses one type of energy, a signal of some sort, and converts it into a reading for the purpose of information transfer. A mercury thermometer is an example of a sensor that converts the expansion and contraction of a volume of mercury in response to change in temperature (the signal), to a reading on a calibrated glass tube giving information about ambient temperature. Other sensors, such as a thermocouple, produce an output voltage or other electrical output which may be attached to a meter for reading a change or interpreted by another device (such as a computer). For accuracy in the application a calibration of the sensor and its output information is necessary.

Sensors are used in everyday objects such as touch-sensitive elevator buttons and lamps which dim or brighten by touching the base. There are also innumerable applications for sensors of which most people are never aware. Applications include automobiles, machines, aerospace, medicine, industry, and robotics.

A sensor's sensitivity indicates how much the sensor's output changes when the measured quantity changes. For instance, if the mercury in a thermometer moves 1cm when the temperature changes by 1°, the sensitivity is 1cm/1°. Sensors that measure very small changes must have very high sensitivities.

India at dawn side

2008-01-14T05:07:00.000-08:00

Recently india had lost in cricket match with srilanka which was held at Australia. It looks so gloomy on that day for me beacause of their performance. Actually there is a tri-series between India, Australia, Srilanka. For the first two matches especially to India, were ended with draw due to climate problem over there.Because of that India got initially two points. Later it played with Australia and showed great performance with Australia by winning against them. Because of that win, India has stood up in first place in the comparison scoreboard. But the bad thing is, it has been lost in srilanka hands. Atcually it was a easy win for Indians but due poor bowling sreesanth india has lost it's game. Anywayz let us see who will win this series. Letz hope for the best.

mobile robots

2008-01-01T07:37:00.000-08:00

NASA's Frogbot uses springs, linkages and motors to hop from place to place.

NASA's FIDO Rover is designed for exploration on Mars

Urbie can explore areas that are dangerous to humans

Mobile robots stand in for people in a number of ways. Some explore other planets or inhospitable areas on Earth, collecting geological samples. Others seek out landmines in former battlefields. The police sometimes use mobile robots to search for a bomb, or even to apprehend a suspect.

Mobile robots also work in homes and businesses. Hospitals may use robots to transport medications. Some museums use robots to patrol their galleries at night, monitoring air quality and humidity levels. Several companies have developed robotic vacuum.

For a mobile robot ,robotic arm plays major role in it's whole process,Robotic arms are relatively easy to build and program because they only operate within a confined area. Things get a bit trickier when you send a robot out into the world.The first obstacle is to give the robot a working locomotion system. If the robot will only need to move over smooth ground, wheels or tracks are the best option. Wheels and tracks can also work on rougher terrain if they are big enough. But robot designers often look to legs instead, because they are more adaptable. Building legged robots also helps researchers understand natural locomotion -- it's a useful exercise in biological research.Typically, hydraulic or pneumatic pistons move robot legs back and forth. The pistons attach to different leg segments just like muscles attach to different bones. It's a real trick getting all these pistons to work together properly. As a baby, your brain had to figure out exactly the right combination of muscle contractions to walk upright without falling over. Similarly, a robot designer has to figure out the right combination of piston movements involved in walking and program this information into the robot's computer. Many mobile robots have a built-in balance system (a collection of gyroscopes, for example) that tells the computer when it needs to correct its movements.

Bipedal locomotion (walking on two legs) is inherently unstable, which makes it very difficult to implement in robots. To create more stable robot walkers, designers commonly look to the animal world, specifically insects. Six-legged insects have exceptionally good balance, and they adapt well to a wide variety of terrain.

Some mobile robots are controlled by remote -- a human tells them what to do and when to do it. The remote control might communicate with the robot through an attached wire, or using radio or infrared signals. Remote robots, often called puppet robots, are useful for exploring dangerous or inaccessible environments, such as the deep sea or inside a volcano. Some robots are only partially controlled by remote. For example, the operator might direct the robot to go to a certain spot, but not steer it there -- the robot
