Robotics or artificial intelligence (AI) are used in manufacturing, in search, in rescue missions & in the military.

They are used in factories all over the world and many people recently have lost their jobs as Robots have become more efficient and precise than the humans.

Advantages of robots

The people should know the importance of robots to help them to determine when to use and when to not use robots.

Robots can go to the planets. They can be used to explore the space.

They can spy on the people in ways the people can’t move and from views the humans can’t reach.

Robots can go far down into the unknown places where humans would be crushed.

They can give us the information that humans can’t get.

They can work at places 24/7 without any salary and food. Plus they don’t get bored.

Robots can perform the tasks faster than humans and much more consistently and accurately.

They become more common each and every day.

The robotic pets can help the patients with depression and they keep them active.

Most of the robots are automatic so, they can move without any human interference.

They can entertain us and they can help us in certain tasks.

You can send them to a dangerous environment such as the deep sea or the war-zones.

You can use robots to produce the products in the factories such as assembling cars.

They can also be used to build parts for many products such as plane parts, car parts & construction supplies.

Robots do anything which we need to be precise & accurate.

New jobs are created because people have to fix and design robots.

Robots can work without sleep. So, they can work 24/7/365.

The overall cost of the product reduces as the work is done by robotic machines. The product is made through machines, assembled, packaged and distributed from one department to another.

So, this way the overhead cost, including the maintenance cost, is reduced to a lesser level.

Robots can endure a hostile environment of interplanetary space.They are made that the planetary atmospheres do not affect their physical state & performance.

They can replace the human beings in many areas of work.

They can shoulder greater responsibilities and they can be programmed to manage themselves.

Robots can be programmed to reach the Earth’s nadir. They can be used to dig for the fuels. They can be used for mining purposes.

They can be harnessed for exploring the depths of oceans. They can be used to overcome the limitations that humans have.

Robots can be used in carrying out repetitive & time-consuming tasks efficiently. They are used to do dangerous tasks.

They can adjust their parameters like their speed & time. They can act quickly, unaffected by the factors that affect the humans.

Robots do not require sleep or take breaks. They are able to function without stopping.

When employed to carry out dangerous tasks, the risk to the human health & safety is reduced.

They can work a long time without service or maintenance and they can be more productive than people.

Robots cannot tremble or shake as human hands do. They can have much smaller & versatile moving parts than the people.

They have performed medical surgeries because they can be faster and more precise than people.

Robots are designed to work in harsh environments like in space, without air, underwater & in the fire.

They can be used instead of people when human safety is a concern.

They can come in any size. Whatever size needed for any task can be created.

Robots can do jobs that people are unwilling to do. Many robotic probes have been sent throughout the solar system to never return back to Earth.

They can be stronger than people. Robots in warfare eliminate putting more people at risk.

Disadvantages of robots

Robots need a supply of power.

People can lose jobs in factories.

They need maintenance to keep them running.

It costs a lot of money to make or buy robots. The software and the equipment that you need to use with the robot cost much money.

Robots cost much money in maintenance & repair. Programs need to be updated to suit the changing requirements. The machines need to be made smarter.

In case of breakdown, the cost of repair may be very high. The procedures to restore lost code or data may be time-consuming & costly.

Robots can store large amounts of data but the storage, access, retrieval is not as effective as the human brain.

They can perform repetitive tasks for a long time but they do not get better with experience such as humans do.

Robots are not able to act any different from what they are programmed to do.

With the heavy application of robots, humans may become overly dependent on the machines, losing their mental capacities.

If control of robots goes in the wrong hands, robots may cause destruction.

Robots are not intelligent or sentient. They can never improve the results of their jobs outside of their predefined programming.

They do not think. They do not have emotions or conscience. This limits how the robots can help & interact with people.

Robots can take the place of many humans in factories. So, people have to find new jobs or be retrained.

They can take the place of the humans in several situations. If robots begin to replace the humans in every field, they will lead to unemployment.

Humans fear robots. Robots inspire two types of fear: firstly, that they might take over our jobs, and secondly, that they could take over the world.

Robots will steal our jobs. Robots have the effect of increasing productivity rather than eliminating jobs.

Robotics become increasingly present in our everyday life, with household robots, medical, industrial, on production lines, not to mention airports, banks, and hotels.

So, robots may dominate the human species.

Robots can operate on the basis of information fed to them through a chip, when one thing goes wrong the entire company bears a loss.

Robot can save times, but can also result in a lag.

It is a machine so you can’t expect too much from them. If the robot has malfunctioned, you need extra time to fix it, which would require reprogramming.

If robots would do all the work, and humans will just sit and monitor them, health hazards will increase rapidly. Obesity will be on top of the list and less labour at workplaces.

THE DEFINITION OF A ROBOT - Science fiction has become science fact with robots and robotics - A robot can be defined as a programmable, self-controlled device consisting of electronic, electrical, or mechanical units. It is a machine that functions in place of a living agent. Robots are especially desirable for certain work functions because, unlike humans, they never get tired; they can endure physical conditions that are uncomfortable or even dangerous; they can operate in airless conditions; they do not get bored by repetition, and they cannot be distracted from the task at hand. The concept of robots is a very old one yet the actual word robot was invented in the 20th century from the Czechoslovakian word robota or robotnik meaning slave, servant, or forced labor. Robots don't have to look or act like humans but they do need to be flexible so they can perform different tasks. Early industrial robots handled radioactive material in atomic labs and were called master/slave manipulators. They were connected together with mechanical linkages and steel cables. Remote arm manipulators can now be moved by push buttons, switches or joysticks. Current robots have advanced sensory systems that process information and appear to function as if they have brains. Their "brain" is actually a form of computerized artificial intelligence to perceive conditions and decide upon a course of action based on those conditions. Common industrial robots are generally heavy rigid devices limited to manufacturing. They operate in precisely structured environments and perform single highly repetitive tasks under pre-programmed control.

The Definition of a Robot

Science fiction has become science fact with robots and robotics

A robot can be defined as a programmable, self-controlled device consisting of electronic, electrical, or mechanical units.

More generally, it is a machine that functions in place of a living agent.

Robots are especially desirable for certain work functions because, unlike humans, they never get tired; they can endure physical conditions that are uncomfortable or even dangerous; they can operate in airless conditions; they do not get bored by repetition, and they cannot be distracted from the task at hand.

The concept of robots is a very old one yet the actual word robot was invented in the 20th century from the Czechoslovakian word robota or robotnik meaning slave, servant, or forced labor.

Robots don't have to look or act like humans but they do need to be flexible so they can perform different tasks.

Early industrial robots handled radioactive material in atomic labs and were called master/slave manipulators.

They were connected together with mechanical linkages and steel cables. Remote arm manipulators can now be moved by push buttons, switches or joysticks.

Current robots have advanced sensory systems that process information and appear to function as if they have brains.

Their "brain" is actually a form of computerized artificial intelligence (AI).

AI allows a robot to perceive conditions and decide upon a course of action based on those conditions.

Components of Robots

·       Effectors — "arms", "legs", "hands", "feet"

·       Sensors — parts that act like senses and can detect objects or things like heat and light and convert the object information into symbols that computers understand

·       Computer — the brain that contains instructions called algorithms to control the robot

·       Equipment — this includes tools and mechanical fixtures

Characteristics that make robots different from regular machinery are that robots usually function by themselves, are sensitive to their environment, adapt to variations in the environment or to errors in prior performance, are task oriented and often have the ability to try different methods to accomplish a task.

Common industrial robots are generally heavy rigid devices limited to manufacturing.

They operate in precisely structured environments and perform single highly repetitive tasks under pre-programmed control.

There were an estimated 720,000 industrial robots in 1998.

Tele-operated robots are used in semi-structured environments such as undersea and nuclear facilities.

They perform non-repetitive tasks and have limited real-time control.

ROBOTIC BUILDING CONSTRUCTION - Robotic building construction has the following advantages: Robots can be extraordinarily precise in construction. Robots can work 24 x 7 in a wide range of conditions. They eliminate human problems in construction: not showing up for work, showing up drunk, mistakes, laziness, injury, the need for safety, the need for health insurance, fights with co-workers. Specialized robots could work in small, dark, airless spaces that are unsafe for humans, or on the facades of tall buildings without facing vertigo. All these factors make them much cheaper and more reliable than conventional construction in the long run. They eliminate the potential risks from accidents and lawsuits, assuming there are no humans on site. Robots will need enough situational awareness to be able to move around a construction site, and enough multi-tasking ability to work with a range of materials and techniques. The current crop of robots represents the industry taking its 'baby steps' towards solving the problem. Until then, one is more likely to see architects using robots in novel ways, to fabricate interesting shapes and forms that cannot be done in the traditional way. It’s possible that robotic construction will enable an entirely new approach. Rather than trying to make a robot emulate a human, what if swarms of robots were each given a task, and limited intelligence, to build structures, just like ants build anthills?

These construction robots never need a lunch break
Robotic Building Construction
understandconstruction.com



A number of individuals and companies across the world are developing robotic construction systems.
While these usually grab a lot of headlines, the reality of the situation needs closer study.
Lets' begin by understanding why people are interested in robotic construction:
ADVANTAGES OF CONSTRUCTION BY ROBOTS
Robotic building construction has the following advantages:
Robots can be extraordinarily precise in construction
Robots can work 24 x 7 in a wide range of conditions
They eliminate human problems in construction: not showing up for work, showing up drunk, mistakes, laziness, injury, the need for safety, the need for health insurance, fights with co-workers
Specialized robots could work in small, dark, airless spaces that are unsafe for humans, or on the facades of tall buildings without facing vertigo
They tend not to form unions.
All these factors make them much cheaper and more reliable than conventional construction in the long run.
They eliminate the potential risks from accidents and lawsuits, assuming there are no humans on site.
SO, DO THEY ACTUALLY WORK?
Let’s look at a few building robots:
Construction Robotics is a US based company that has developed 
a bricklaying robot. Called SAM, or semi-autonomous mason, 
the robot has been used to lay bricks on a number of projects.
Another bricklaying robot from Aussie company Fastbrick Robotics
MIT Robot that 3D print or build foam structures that can in turn be used to make concrete walls.
As you can see, most robots consist of long arms that can place brick, foam, or other materials accurately.
While this is no doubt impressive, there is a long way to go before robots will completely replace construction by humans.
Let's now talk about at some of the problems faced by robots at construction sites:
o  Robots were originally developed for use in factories.
They operate in highly controlled, clean, clutter-free environments, most often without humans in close proximity.
A building site is another matter altogether.
First of all, each site is laid out differently, so a robot would have to be intelligent enough to recognize where it is on the site and then move to the right location.
Secondly, building sites are often chaotic, disorganised spaces with materials, tools, debris, and wires spread about.
Many areas of the site will have unpaved soft soil, into which a robot will sink if it steps off the beaten path.
There will be dust, rain, ice, and storms. There will be humans walking around. Getting a robot to work in these conditions is very difficult.
o  Buildings nowadays are complex entities, and construction entails many different trades coming together to work in perfect sync with each other.
The robots that you see now each perform one specialised task. It is impossible for a bricklaying robot to perform delicate tasks such as installing electrical cabling.
Human dexterity, intelligence and situational awareness, developed over hundreds of millions of years, is currently far superior.
Services like power cables, data and information cables of many kinds (voice, security, fire alarm, BMS) have to be woven through the fabric of the building.
So, a robo-mason must also be able to lay conduits for electrical wires, plumbing pipes, and must be able to perform waterproofing tasks.
SO, WHEN WILL I MOVE IN TO A BUILDING MADE BY ROBOTS?
In our (sometimes humble) opinion, this will not happen before 2040 or so, when robots become a lot more street-smart, and develop some kind of 'general intelligence'.
Robots will need enough situational awareness to be able to move around a construction site, and enough multi-tasking ability to work with a range of materials and techniques as described above.
The current crop of robots represents the industry taking its 'baby steps' towards solving the problem.
Until then, one is more likely to see architects using robots in novel ways, to fabricate interesting shapes and forms that cannot be done in the traditional way.
Enjoy the examples below:
ETH University Zurich develops robot construction
SELF ASSEMBLING BUILDINGS?
Its possible that robotic construction will enable an entirely new approach.
Rather than trying to make a robot emulate a human, what if swarms of robots were each given a repititive task, and limited intelligence, to build structures, just like ants build anthills?
There is no "master architect" or "project manager" in anthills.
Each ant repeatedly adds material, following a very clear set of rules, and the anthill emerges from the collective efforts of the entire swarm of ants.
If we look at human cells, the information or blueprint to construct the cell is embedded within the structure of the cell, in the DNA.
This enables the cells to make copies of themselves.
It may be possible to develop building components that have some built-in geometry that allows them to link together to form buildings in a number of different ways, and perhaps allow humans to program them to link together two or three different ways, thereby allowing a variety of structures from the same module.
In this approach, the robot does not build the structure, but is the structure, as the building is built of thousands of identical mini-robots.
Watch MIT professor and head of MIT's self-assembly lab Skylar Tibbits explain his work in the following TED talk:
This is a site that explains the art and science of building construction in great clarity and detail.  Our goal is to make you understand concepts in building construction.
Written by architects and engineers, the content on the site is actually a result of accumulated years of work experience at building construction sites and design offices.  This expert knowledge of building construction is not available in textbooks!
We also take great pains to ensure that our quality of writing is of a high standard.  We aim to take complicated situations and make them simple and clear, as well as to provide content that is interesting to industry experts and newcomers alike.  Do let us know where we succeed - and where we fail - in this task.
