CLASSIFICATION AND ADVANTAGES/DISADVANTAGES OF ROBOTS

CLASSIFICATION AND ADVANTAGES/DISADVANTAGES OF ROBOTS
Classification of Robots:
The following is the classification of robots according to the Japanese Industrial Robot Association (JIRA):

Class 1: Manual handling device: A device with multiple degrees of freedom, actuate by the operator.
Class 2: Fixed Sequence Robot: A device that performs the next steps of a task according to a predetermined, immutable method, it is difficult to modify.
Class 3: Variable Sequence Robot: Same as in Class 2, but easy to modify.
Class 4: Playback Robot: The human operator performs the task manually by running the robot, which then records the moves for playback; The robot repeats the same movements as recorded.
 Class 5: Numerical Control Robot: The operator supplies the robot with a vibration program without manually teaching the work.
Class 6: Intelligent Robot: Robot to understand its environment and ability to successfully complete a task despite changes in the environment.
The Robotics Institute of America (RIA) only considers class 3-6 as Robots. The Association Francaise de Robotic (AFR) has the following classification:
Type A: Maintaining equipment with manual control for telerobotics.
Type B: Automatic handling equipment with predetermined wheels.
Type C: Programmable, servo-controlled robots with continuous or point-to-point Channels.
Type D: Same as C but with the ability to retrieve information from its environment.

Advantages of Robots:

·      Robotics and automation are, in many cases, increase productivity, security, products, quality and sustainability of products.
·      Robots can operate in hazardous environments such as radiation, darkness, heat and cold marine support, space and so on without the need for life support, comfort or concern for security.
·      Robots do not need an environment like lighting, air conditioning, ventilation and noise protection.
·      Robots work constantly without fatigue or fatigue or boredom. They don't get it there is no madness, no hangovers and no medical insurance or leave.
·      Robots have repeatable accuracy at all times, unless something happens unless they are worn.
·      Robots are far more accurate than humans. Some of the simplest linear accuracy one thousandth of an inch. The new layer-handling robots have micro-inch precision.
·      Robots and their tools and sensors have capabilities beyond humans
·      Robots can process multiple stimuli or tasks at once. Only humans can process it an active stimulus.
·      Workers robots replace human labour, causing economic hardship and worker dissatisfaction and resentment, and the need to regain a replacement workforce.

Disadvantages of Robots:
Robots are not capable of responding to emergencies unless the situation is  included in the response system. They need security measures to do so operators and other machines working with them should not be injured. These include
·      Inappropriate or incorrect responses.
·      Lack of decision-making power.
·      Loss of energy.
·      Damage to the robot and other equipment.
·      Injuries to humans.
Robots, although superior in some senses, have limited capabilities:
·      Knowledge, creativity, decision making and awareness.
·      Degrees of freedom and ability.
·      Sensors and vision systems.
·      Real-time response.
Robots are expensive because of:
·      Initial cost of equipment and installation.
·      Peripherals required.
·      Training is required.
·      Programming required.

HEALTH AND FITNESS

HEALTH AND FITNESS

‘Health is wealth’ and ‘fitness is the key’. What does the health means? Health means ‘being well’, we call a person healthy if he/she fit physically as well as mentally.


Factor affecting our health
Our health and fitness is not something which can achieve on our own. It depends on the physical environment and quality of food they take. Pollution free environment directly affect our fitness. Our habits also determine our fitness level. The quality of food, water and air we intake, all affects our fitness level.
Role of Diet on fitness
The first thing which affects our fitness is food. We must take food which is full of nutritious it means food rich in protein, vitamins, minerals, and carbohydrates. Protein is good for body growth; carbohydrates provide the energy for performing various tasks. Vitamins and minerals build bones and boost our immune system which helps us to fight diseases.
However, taking food in uneven quantity is not good for our health, Taking essential minerals in proper amount are good for health and it is called balanced diet. Balanced diet keeps us fit and healthy. Good food helps us in better sleep, proper functioning of brain, and proper healthy body weight.



Healthy food saves us from many diseases. Reducing the amount of fat in our food prevents us from cholesterol and heart diseases. Roughage helps in cleaning inner body organs.

Impact of Exercise on our health
Exercise is essential for our health, Routine exercise help us to improve muscle power. Exercise helps good oxygen supply and blood flow throughout the body. Heart Lungs and other parts of bodywork efficiently. Our bones get strong and have pain less movement in joint. Exercise also lower our blood sugar level and improve the insulin to work better. Exercise make easy to quit smoking. Exercise releases some chemicals in our body that can improve our mood and deal with stress so reduce the risk of depression.

We should spend at least thirty minutes in exercise. Daily morning walk improve our immune system. Exercise burns our fat and controls the cholesterol level in our body which prevents us from heart diseases. We should also play various outdoor games like cricket, football, volleyball etc to keep us fit. Regular exercise maintains our body fit.
Meditation and Yoga
From ancient time meditation and yoga are the part of our life. They make us physically as well as mentally strong. Meditation also improves our concentration level and our thinking become positive. Yoga makes us stress free it also control our blood pressure. Meditation is the best way to fight with depression.

 

Conclusion
A Person stays happy only when he/she is healthy, because healthy person is less prone to chronic diseases. The healthy mind reacts better in pressure situation and also the self-confidence of a person is increased. Cholesterol level is reduced so risk of heart failure is reduced. Increases the immunity power could fight with cancerous cells. The intensity of bone breakage and fracture is decreased with regular exercise.

CHOICE IS YOURS- GET INJURED OR GET VICTORY


A 5 years child is very excited today as he is about to cross thermal power station which is about 10 km away from his house. The thermal power station which he usually sees from his terrace will now in front of him.



As much as he is going closer to the power station excitement level goes higher and higher.
He is thinking… The thermal power station which is 10km away and still visible from his terrace…
How much bigger it will be…?
As he comes in front of thermal power station he fills with eager. He fills with that much eager as he couldn't forget that moment in the age of 20.


Now the question arises
Why he (not only him everyone) get filled with eager by seeing the object which is much higher?
Why there is record to climb over Mount Everest & have no record to cover a valley?
We are getting afraid to see the depth but filled with eager to see the height… though it is easier to cover kms of depth but takes too many efforts to climb few meters over heights…




Why this eager and fear comes!
Where will we see…?
We look at the output
If we fall in depths
we get injured and
if we climb over heights…
we get victory


If we look into its technical aspects
Gravity supports you when you fall… it opposes when we climb...
Gravity is like negativity /bad habits/bad company you would feel enjoying all but what will be the output you get injured but if we effort beyond all these distractions we will get victory.  





Now the choice is yours you want to get injured or get victory!

Victory
What is it you dream of?
How far will you go?
To show the world your greatness
So everyone will know

Will you go the distance?
Will you pay the price?
Learning all the lessons
And heeding good advice

There are no guarantees
No tricks and no sure thing
There’s  simply strength and passion
That define what hope may bring

It’s when it comes together
The perfect turn of fate
When strength pushes us forward
To enter Victory’s gate





A Change to fly

Silence does surround you
Just listen to the wind
Feel the changed direction
Of what will soon begin

The answers are around you
The path has been revealed
Where passion turns to motion
And wounds of old are healed

Do you have the courage?
To take the step upon the road
Freeing up your purpose
As you cast aside your load

Lightened of your burden
So many things you’ll try
Freed of chains and baggage
Give you a chance to fly




The Time is Now

Now’s the time to do those things
That lifts you and give you wings
To shed the smock of sullen days
And cast away the gloom and haze

Tap into the strength you know
And feel your power start and grow
Finish up those things undone
And start anew and have some fun

Prepare now for a new venue
With much to say and much to do
Put behind those things of waste
And set a course with all due haste

Worlds that beacon call you near
To offer things that holds you dear
Enter in with open hearts
                                            And join with those who you’re a part

DATABASE: SQL vs NoSQL


DATABASE: SQL vs NoSQL
With the advent of huge amount of data in technological era, SQL and NoSQL databases are majorly used. SQL stands for Structured Query Language which is used mainly for relational database management system and NoSQL refers to Not Only SQL which is a collection of non-relational data storage systems.
There are different types of RDBMS such as MS Access, Oracle, MySQL, Informix, SQL Server, Sybase which uses SQL as their standard database query language. Today SQL databases become an unavoidable part of IT department of any organization. MySQL is a Relational Database based SQL implementation for the web which is now being used in very large-scale websites such as Facebook etc.

There is relaxation of one or more of the ACID properties in NoSQL. Some of the NoSQL databases are Cassandra, CouchDB, Hadoop & Hbase, MongoDB, StupidDB. The aim of this blog is to compare these two SQL & NOSQL databases and tries to figure out which is better in terms of their performance & scalability.
It is a well known fact that SQL databases have taken over the world of data technologies and have been the primary source of data storage over decades. SQL databases are generally for accessing the relational databases.
Soon enough data started growing exponentially and scalability became a major issue, at that time NoSQL rolled in to save the day.NoSQL databases existed since 1960, but recently they have gained more popularity especially for providing the scaling feature.
The major difference between MongoDB and SQL Databases is the way of handling the data. In SQL databases, data is stored in tabular form of two-dimensional row-column structure while in MongoDB document model is followed, which allows storage of any type of data.


Following are the major differences between SQL and NoSQL databases :

SQL Database
NoSQL Database (MongoDB)
Purely relational database
Non-relational database
Supports SQL query language
Supports JSON query language
2-dimension Table based
Collection and key-value pair based
Row & Column based
Document & Field based
Data storage requires predefined structure
Stores data in flexible manner
Support triggers & foreign key
Doesn’t support triggers foreign key
Contains predefined schema
Contains dynamic schema
Not for hierarchical data storage
Best for hierarchical data storage
Vertically scalable (increasing RAM)
Horizontally scalable (add more servers)
Follows ACID properties (Atomicity, Consistency, Isolation and Durability)
Follows CAP theorem (Consistency, Availability and Partition tolerance)


MongoDB Documents makes it easy for developers to map the data used in the application to its associated document in the database. While in SQL Database, creating a table with columns mapped to the object’s attributes in programming language is a little tedious.
When it comes to choosing a database, one of the biggest decisions is selecting a relational (SQL) or non-relational (NoSQL) data type structure. While both options are viable, but still there are certain key differences between the two and user chooses the option according to his requirements.

Now and Then Corona- A fear or Blessing in Disguise

Few days of Lock down and look how fresh everything outside feels. Air feels like pure Oxygen coming all the way from Himalayas. 



When u hear Birds chirping it feels like you are in Jungles of Amazon. April 1st is feeling like its making fool of us with such a pleasant weather around. No more Danger zone alarms in Delhi or Even odd system news when it comes to Air Quality Index. No more Air Quality Index warning in cities of NCR. No more fear of wearing white shirt when you are on Scooty or Bike. No more suffocation in Traffic.

Dogs have started showing courage of Groaning looking at Humans like we are entering their territory. So quickly it’s forgotten that there use to be so many humans that these dogs never use to get place to walk. No more busting our ears with noise. No more burning of Life endangering fuel. No more fumes that choke your throat and fill your lungs with Darkest and deadly fumes.




No more factories exhausting dark cloud over the clear blue sky. No more running for work at 0830 AM. No more late night meetings. No more rushing around at 120 KMPL endangering your and other’s lives. No more synthetic food to eat. No more staying outside your home. No more traffic challans. No more road accidents. No more hatred gatherings of people spoiling the public harmony. No more burning of 500kms of fuel to see Taj Mahal which itself is getting spoiled by the fuel you burnt. No more waiting in queues for Railway tickets. No more overcrowded trains or buses. No more fight for land among countries.




Now comes time when you are with your family. When you can feel how easy or difficult it is to work in kitchen. Sky is now smiling with no dimples i.e. Ozone layer has now started recovery. Birds are not thirsty anymore. Sky is clean. Nature is now playing the smoothening music. Family started spending together now. Rivers are cleansing themselves. Roads are clean now without Swachh Bharat Abhiyaan. Yoga started at homes not willingly but out of boredom. Buildings looking clean now. You can feel the fragrance of mother earth and its creatures. You can now stand with trees and feel them actually talking to you when you close your eyes. Countries now want to look for their people rather than attacking others. Humans are now looking to gather food for them rather than racing to take other's share.

Race to be the best has come to halt and regime to survive has started now.

Finally everybody is striving for common cause to beat the demon and survive.

But question is who this demon is!!!

Is it Corona the Virus or Is it the Demon among ourselves because whatever was spoiled was not spoiled by Corona and whatever has restored back is not actually due to Corona. Reason for all this was Human and its mindset and is Human and its change in behaviour.
Corona is just an excuse to make us realise what we were, what we became and what we want to be in near future.


Corona is just helping us see our future options i.e. not just the worst one but glimpses of how better it can be.
It's upto you to decide what your and your future's future should look like.
Decide and act accordingly.
Although Human is the best creature of Mother earth but time has changed and Virus proved to be the bestie for earth now.
English may not be perfect but you will get what i meant and what our future should be like😊
With complement for present and Future.
