What used to be sci fi is now all around us. It's been decades since this revolution has happened, just without the self-aware robots taking over the world and becoming overlords making us work in mines. On the contrary, they are being deployed in spacecrafts to have them dock, but some of them are even vacuuming our kitchen. Spotless technology is and always will be a catalyst for change, just not as violent as movies make us think it would be. But that's still a whole lot of history that went into these robots that we used to do.

And some problems that the engineers struggle with three or four decades ago still remain unsolved. All the convenience we already enjoy, thanks to these robots, took decades of work by engineers and scientists. So it might just help people like you. And I understand why do we not have these super intelligent robots taking over the Earth or even taking care of all our daily needs? But if we are going to talk about the evolution of robots, we might as well just go ahead and talk about what a robot is.

It's a quite simple idea. So a robot is a machine designed to accomplish a particular task. That's it. No more. No less. The robots have sensors for inputs, control systems for decision making and effectors for output. Sounds simple enough, doesn't it? But it has taken decades of work to get right. It might come as a surprise to a lot of you that the laws of robotics have not found their inception through a physicist or an engineer.

Rather, an author called Isaac Asimov has made these laws and coined the term robotics in the process. The modern day laws are also loosely based on this. Now the concepts of artificial servants or soldiers dead, at least as far back as the ancient legends and mythologies. And if I talked about every little step or advancement of these robots, you'd probably have to sit here all day. So I'll try to put it as simple as possible. So what I've done here is I've segregated this into various generations.

So I think the industry is a good place to start because that's where robots originally started to add purpose, since factory work can be repetitive and requires quite heavy lifting. It's ideal to employ robots in this domain.

The world's first industrial robot, UNAMID, was installed in a General Motors production line in New Jersey 1961. The original UNAMID consisted of a large computer like Box, joined with another box which was connected to an arm. It had systematic tasks stored in a huge magnetic drum. The machine undertook the job of transporting dye castings from an assembly line and welding these parts into auto bodies, a dangerous task for workers who might be poisoned by the toxic fumes or lose a limb if they were not careful enough.

From then on, Japanese robots have led the field, Waseda University initiated the robot project in 1967 and in 72 completed the robot won the world's first full scale humanoid intelligent robot. Its LEMP control system allowed it to walk with lower limbs and to grip and transport objects with hands using tactile sensors. Its vision system allowed to measure distances and directions to objects using external Receptos artificial eyes and yours. It was the best of its time, and it could also converse in Japanese with people using a conversation system and an artificial mouth.

This was truly the world's first Android Android being manlike and a truly lived up to its meaning. Another boat from this generation is the FC are on the scarer, this acronym stands for Selective Compliance Assembly Robot arm by what you it's only an arm which was rigid in the Z axis and pliable in the X and Y.

The joint of Dooling arm layout is the closest we could get that time to our human arms. It was quite beneficial in the transferring domain where it could transfer parts from one cell to another or for loading and unloading processes. To be honest, really, it's a beautiful invention for lazy people like me else I wouldn't even get up for the TV remote myself.

Moving on, we have the third generation now.

The third generation did not have much of a leap, but boy, your boy, did it take the world by storm when it did presenting to you were born to the musical robot. This bot could not only read musical score, but also play thanks to its inbuilt motors in the arms with its visual and vocal subsystems. It could successfully hold conversation as well.

With that, we move to Gen four and the first of its kind, artificial intelligent robots are the EIB All, which is a part of a series of robotic pets designed and manufactured by Sony, having actuators for lifelike movements in its legs, neck and tail. Imagine having a pet, but none of the dirty work. Isn't it a dream with sensors to enable touch sight range, finding an actual dog like speed? This one's a keeper. In November 2017, Sony announced a new generation of eyeballs.

After almost 11 years, they promise that this one is going to be more doglike than ever. I can't really wait for its reveal, can you? So with that said, let's move to another board in this generation where the artificial intelligence really shines through. Originally designed to test how machines work in microgravity, this one outshone its predecessors with a wider range of sensing reduced flammability and reduced electromagnetic interference. It is the perfect space help for the International Space Station, according to experts.

Any robot of a sort yet to be seriously put into operation is a fourth generation robot. Examples of these might include robots that reproduce and evolve or those that incorporate biological as well as mechanical components.

That we might say that a fifth generation robot is something that nobody has designed, but they're still a robot I would like to talk about that brings the world's tomorrow to its today. This is Sophia, the robot celebrity mostly known for her human like appearance and behavior compared to its previous robotic variants. Sophia uses artificial intelligence, visual data processing and facial recognition. Sophia also imitate human gestures and facial expressions. She herself is capable of more than 200 different facial expressions.

She can even answer certain questions and make simple conversation on predefined topics. Sophia use a speech to text technology and is designed to get smarter over time. The information is shared in a cloud network, which allows input and responses to be analyzed in a block chain technology. She was designed predominantly to help the elderly in nursing homes. So with that I conclude my list of generations of robots.
