An Introduction to Robotics and Automation
So, ever wondered what is this ‘Robotics and Automation’? Okay, let’s break it down to ‘Robotics’ and ‘Automation’.
What on earth is Robotics?
‘Robotics’, cool word, eh? Well, yeah, it’s quite cool… not because of its name, but because you make and work with cool stuffs here, like robots. Okay, let me ask you one question. What is it that comes to your mind immediately after hearing the word ‘robot’?
Is it something…
- that does your task
- that obeys you (and sometimes disobeys) :)
- that can perform stuffs that we humans cannot
Or, is it something like this…
So, many of you have a misconception that robots are big machines like those shown in movies like Transformers, etc. (now don’t say that you haven’t seen the movie ;)). Sorry to disappoint you all, but I would like to clarify that no such robot has ever been made practically. Robots which have a shape like humans are called humanoids. Research and Development is being carried out in this field. Till now, not even a single perfect humanoid has been made (so forget about Rajnikanth’s movie Robot).
Now, in the pictures shown above, you can see a few cars, tanks and moving vehicles. Yes, they are robots. You can also see a fish. For your information, it’s a mechanical (artificial) fish that has been developed by engineers. Yes, it is a robot. You can also see a few humanoids (one of them is ASIMO).
But what about the pictures of a gorilla, mosquito, bacteria, humans, etc.? Well, even they are robot, biological robots!
Okay, so now, can you define a robot? Think hard and try to come up with your own unique answers. By the way, there are many definitions of a robot, the simplest one as follows:
“Any matter which has at least one degree of freedom is called a robot”.
Confused regarding degree of freedom? Well, you should be ;-). Degree Of Freedom (DOF) represents the direction in which a robot can make movements. Say, one DOF means that the robot has only one moveable part and can move only in one direction. Two DOF means that the robot is free to move its parts in any two different directions. For example, the following robotic arm has 3 DOF as marked. Please note that all the three degrees of freedom are rotatory, not translatory.
So, this proves that each and every pic that is shown above is a robot! Convinced? If not, please comment below so that I can convince you. ;-)
And to your surprise, there are also laws governing robotics! The Three Laws of Robotics :
- A robot may not injure a human being or, through inaction, allow a human being to come to harm.
- A robot must obey any orders given to it by human beings, except where such orders would conflict with the First Law.
- A robot must protect its own existence as long as such protection does not conflict with the First or Second Law
So, by now, you can easily say what on earth is Robotics? What do you think? Well, it’s all upto you the way you want to define robotics. It can be
- study of robots
- making of robots
- playing with robots :)
- practical use of robots
- artificial intelligence (AI)
So, any idea what is this “AI”, or Artificial Intelligence? Well, I ain’t gonna tell ya, google it out yourself… ;)
What on earth is Automation?
You must have heard the word Automatic. What does it mean? In simple words, an automatic device means that it can work with minimum or no human intervention. Similarly, Automation means the act of implementing the control of equipment with advanced technology; usually involving electronic hardware and robotic equipment. The main motto of automation is to reduce human work. It is an outcome of the varied application of robotics.
Applications of Robotics and Automation
Whether it is outer space, home, farms, industries, hospitals, defense etc, robotics and automation plays a major role. Be it for research and exploration purpose, education, entertainment or disaster mitigation, automation is very essential. The following examples will clarify a bit more:
- intelligent home i.e. house automation systems are becoming popular day by day
- manipulative arms controlled by humans
- unmanned vehicles for defense and exploration
- automated harvesters and automated dairies
- car manufacturing process
- food processing industry and packaging industry
- robotic suit for nurses
- surgery-assisting robots
- interactive robots that exhibit behaviours and learning ability
- education is integrating technologies in a creative format and robotics involves all key learning areas such as maths, arts (i.e. materials and design), English, sciences (i.e. chemistry, physics, mechanics, electronics) and social skills
So, I guess you have got a good idea of what robotics and automation is! We will start with robotics and then move towards automation.

Thank you, these articles are really very easy to follow and understand. I have been hanging around this website only for a one day, and I have already learned much more than spending week using google.. Keep up the good work!
Thanks TMS! :)
i disagree !
for me: robot = a machine that do stuff (self or man controlled).
very nice blog dude.
Yeah.. the definition that I gave above is a bit technical though :P
Dude (essam gndelee) But all machines are not robots…
Reblogged this on roboVITics.
What a motivating start!!Great!!
As a person who decided to go Computer Engineering I really need to know more about electronics, computer components and other staff related to this field. I like the blog and this is the first time I enjoy and love to read a blog written in English because it’s a second language and still feel uncomfortable reading in it, so thx.
All the best for your endeavors! :)
Thank Alot for these posts… now i dnt hav to google much for robotics because of your posts… THNX.. ;)
Thanks for the compliment Nabil! This is why I created this website! :)
This is THE BEST intro to Robotics I have ever come across! My college doesn’t have a good robotics club and now I have a ready reference to help me with my hobby projects!
Great work guys!
Thanks for the feedback ;) and if you are willing to have workshop by in your college from us, please go to http://www.maxembedded.com/workshops and fill the form. We will get back to you shortly.
Keep Reading, Keep Sharing :D
honestly was searcing for a robotics informing and learning website which also informs me about how to write a programm to burning and running the same. And i am too happy to anounce that i have finally got my search ( I think so after felling in “love at first sight” with this site)
Thanks Himanshu for the feedback.
Keep Reading, Keep Sharing :D
Thanks Himanshu! It’s a two-sided love.. maxEmbedded loves you too! Haha.
