Journey of robotics from Da Vinci to the latest models

Did you know Leonardo da Vinci , artist of the famous Monalisa, also had a sketch of a robot in his notebook?

Let us take you through an impeccable journey of robotics from Da Vinci to the latest models. The Italian artist, who lived from 1452 to 1519, had a sketched out plan for building a robot. This robot, according to the analysis of its sketch, was able to perform the basic human movements. A few examples of the movements would be sitting up, moving its head and jaw and waving its arm. It was known as “Robotic Knight”.

But this was not the first instance of robotics in the history. Around 350 BC, the great Greek mathematician, Archytas of Tarentum built the first model airplane which was

nothing but a mechanical bird propelled by steam.

I know, many of you would be saying that airplane does not fall under robotics. So to clear it up, a robot is nothing but a mechanical device that is able to make “smart” decisions. This “smart” decision can be made either by a electronic circuit present in the machine, or a computer program that controls movements. In the above airplane’s case the movement was done with the help of steam. Now that is simply smart!

Since then, Robotics has grown leaps and bounds as an independent stream of studies. We are at the brink of developing even artificial emotive intelligence.  But did you know that most simple and everyday utility robots could be broadly classified on the basis of either application or their movement?

Medical robots:

These are used in the hospitals and medicine industry. To state the advancement in robotics, some of these robots assist the doctors in surgery while many of them help for lifting different kinds of heavy material. Don’t believe me? Have a look at the below picture:

Military and Space robots:

Robotics has found its applications in critical fields like military also. In order to reduce human causality, robots are used for bomb disposals. Many of us hear about “drones” these days. Drones are nothing but robots that provide our soldiers with the aerial surveillance and data.

For collecting the data from Mars for research purposes, NASA had used a robot named as “Mars Rovers”.

Hobby and competition robots:

In order to generate interest in kids for robotics, many nations have started holding competitions of different levels. At early stages, these were just line following robots. Great way to learn, have fun and develop a healthy competitive spirit.

After looking at the classification of robots on the basis of the purpose they serve, let’s also look at some categories of robots based on their movement.

  1. Polar robot: It is used for many purposes, one of them being machine handling. It has a base that can rotate, and mounted on the base at certain height is the arm.
  2. Cylindrical robot: Designed for spot welding and assembling purpose. Arms are form a cylindrical co-ordinate system.
  3. Cartesian robot: It is built for pick and put work and helps in assembly of different heavy machinery parts. Its arms are designed to similar to Cartesian co-ordinate system and hence the name.
  4. Jointed arm: Two armed robot whose joints are free to rotate.
  5. SCARA robot: Its full form is Selective Compliance Assembly Robot Arm. As we can see in the picture, it is a four axis material handling robot.

A few of the top notch robots currently present in the world:

The current trend in robotics favors humanoid robots that is, robots that are able to perform and behave s closely as possible to humans. Now to make things a lot interesting, let us look at the top five humanoid robots present in the world:

  1. ASIMO:  It would be injustice to this terrific robot, ASIMO (Advanced Step in Innovative Mobility ), if we do not include him. It is three foot tall robot that can walk up and down the stairs, has the ability to run or walk on a plain surface and also pick up objects. It can also respond to voice commands and turn its head to the direction of any noise.


  1. PETMAN: Protection Ensemble Test MANnequin (PETMAN) walks in a very human like manner across the uneven terrains too.


  1. NAO: It is more precise and advanced than ASIMO. Used in teaching social skills to autistic children. I am sure you would find it absolutely adorable.


  1. Atlas: This can move in any kind of terrain. It does not have that much human like feature but its performance is quite good.


I don’t know about you, but after learning so much about this amazing piece of machinery, I wonder if I could build one of my own. Oh wait! I can and so can my kid. With “Bristle Bot Simple Robot” kit present on it becomes fairly easy to get

things going. And of course, I can brag my knowledge about robotics to my colleagues too. Well I am going to order one right away. You can too. Help yourself at Bristle Bot Simple Robot.

5 interesting STEM careers

Think of a coder in his habitat. I’m sure you pictured a grimy teenager hunched over a laptop in a dark, dank cubicle. But that was the stereotype of yesteryear. Today, STEM careers have taken on a wildly different perception. Some of the coolest jobs ever require a background in Science, Technology, Engineering and Math. STEM careers are far from the public perception of robotic employees and sterile, tiny cubicles in a corner. Let’s have a look at the 5 interesting STEM careers below:-

5 STEM careers you’ll sure covet!!

  1. NASA Rover Drive

Curiosity, the Mars rover touched down on the Red Planet in August and has beamed back photos, news of the weather and other data that’ll help us understand the planet better. (We have to. We might be living there soon!) While we’re all in the awe of this piece of machinery, we forget that there’s a human at the helm, navigating Curiosity over Martian terrain. It is one of the coolest jobs on (and beyond) earth. Becoming an astronomer is cool, but if you want to see some real action a rover driver is the best job for you.

  1. Statistician – The Numbers People

Statisticians are not poor souls struggling with a fat book covered with numbers. Everyone who’s seen “Moneyball” knows that sports are games of data. Many sports teams have statisticians on board who analyze data, do the number crunching so that players can decide their moves in the game. ESPN has an entire analyst group.  If you’ve ever wondered how announcers come up with those totally obscure stats right after a game, the answer is that it’s someone’s job to research that data. It’s also someone’s job to figure out how to optimize the game by studying them.

Electric Bulb

Electric Bulb

Thomas Edison, after failing at making the electric bulb famously said, “I

haven’t failed. I’ve just found 10,000 ways that won’t work.” In the end, he did

indeed invent the electric bulb and is counted among the most brilliant scientists. It’s great advice for when you hit a low in your life.  Let’s know more about this amazing invention.

Electric Bulb

Electric Bulb

An electric bulb is a device that produces visible light when electric current flows through its filaments. It is the most common form of artificial lighting and is essential to modern society. Just think! If there were no bulbs, we would spend our nights huddled near a candle desperately trying to finish our assignments in the dim light.

 Types of electric bulbs

  • Incandescent bulbs

Incandescent bulbs produce light using a filament heated white-hot by electric current. A bulb is made up of a positive and a negative terminal embedded with a tungsten filament that joins the two. The filament is encased inside transparent glass. The air inside the glass is an inert gas that helps prevent the filament from becoming too hot and breaking. It turns electricity into light when electric current passes through a thin wire i.e. a filament. Filament is made up of tungsten. The resistance of the filament produces heat. Eventually the filament gets so hot that it glows. These bulbs are good for household applications. A standard incandescent bulb can last for 700-1000 hours.

Incandescent Light Bulb

Incandescent Light Bulb

  • Fluorescent bulb

These bulbs work by passing current through a tube filled with argon and mercury. This produces ultraviolet radiation that bombards the phosphorous coating causing it to emit light. Its life is about 10,000 to 20,000 hours. It’s very efficient and produces very little heat. These bulbs are ideal for lighting large areas like basements, storage lockers etc.

Fluoroscent Bulb

Fluoroscent Bulb

Approximate Equivalents to Incandescent Bulbs
CFL Incandescent
7–10 Watts 40 Watts
15-18 Watts 60 Watts
20 Watts 75 Watts
20-25 Watts 100 Watts
32 Watts 150 Watts


Compact Fluorescent Lamps (CFL)

CFLs produce little heat and are very efficient. They fit screw type and pin type base fittings. They normally last up to 10,000 hours.

  • Low Pressure Sodium Lamps

Low pressure sodium lamps have high efficiency. They operate much like a fluorescent lamp. There is a brief warm-up period for the lamp to reach full brightness.

  • Light Emitting Diode (LED)

LED lamps produce light by flow of electrons across a band gap in a semiconductor. LEDs are bulbs without a filament. They have low power consumption and a long life span.  This technology is advancing everyday and soon LED bulb will be the bulb of choice for most applications at homes.

Make your child sympathetic towards the Environment

Sympathetic for the environment?

Let’s evolve some ideas to preserve it

Environment, a word that can simply be defined as anything that surrounds us. It includes all living and non-living things that occurs on the earth or thereof and hence is responsible for affecting an individual’s body, mind and heart. In terms of biology and somewhat ecology, all natural materials along with living things, even sunlight, constitute natural environment. So people who remain concerned about the environment are said to be environmentalists. They focus on protecting the environment, most probably by checking the pollution, greenery, population and many more. Now let us make a list of all the problems regarding the environment, along with the ideas to reduce their adverse effects.

  • POLLUTION: Environment is basically polluted when substances with harmful or toxic effects are introduced in it. There are different kinds of pollution like air pollution, water pollution and soil pollution which requires a lot of years to recoup. Everyone might know the consequences of these types of pollution. First of all, air pollution occurs due to increase in the amount of undesirable chemicals in the atmosphere. Effluents from the industries and vehicles are the major source of this. Water pollution is caused due to the deposition of waste materials from the refineries, industries. Some people also have a habit to complete the domestic chores on the bank of river, ultimately polluting it. Soil is also polluted with the industrial substances that reduce the nutrient quantity in soil.

Environmental Deforestation


  • Proper Plantation. Trees not only purify the atmosphere but also beautify the surrounding.
  • Prohibition on Smoking. The part of cigarettes thrown after smoking

    is not degradable and contains toxic substances, which are further improper for the society.

  • Proper checking on car emissions.
  • Start an anti-litter campaign in surrounding.
  • In case you are a pet lover and you have a pet, then be careful while disposing it’s waste.

If you are eager to design your own pollution model or water purification plant, you can have it from .

  • GLOBAL WARMING: The average surface temperature of the earth has increased due to the effect of greenhouse gases, like carbon dioxide and chlorofluorocarbons (CFC’s). Furthermore, these gases are responsible for trapping heat from the sun and retain it within the earth’s atmosphere which is now resulting in climate change. The temperature all over the earth is increasing due to which glaciers has started melting, raising the water level throughout the globe. Excessive snow, flood and desertification are also a result of this.
Environmental Pollution

Environmental Pollution


  • Reduction on usage of refrigerators and air conditioners, since they are the biggest source of CFC’s.
  • Hinder on use of private vehicles. Basically, mandation on usage of public transport.
  • Enhancing plantation.
  • Proper usage of Electricity.
  • Idea of 3R’s should be used: REDUCE, REUSE, RECYCLE – For more knowledge, you must try a DIY model for the same at
  • NATURAL RESOURCE  DEPLETION: With the consumption of fossil fuels like coal, concentration of greenhouse gases increases in atmosphere, leading to global warming.


  • Promotion of usage of renewable resources.
  • Daily life usage of Equipment working on the basis of solar energy like solar heater, solar cooker, solar traffic light, solar lamps etc.
  • Reduction of plastic bags.
  • OZONE LAYER DEPLETION: there is a protective layer around our mother earth whose job is to provide protection against the harmful radiations from the sun. Depletion of the Ozone layer especially relevant with the enhancement in the rate of global warming and greenhouse gases. This can result into various skin diseases, respiratory problems and maybe much more.



  • Elimination of devices probably generating greenhouse gases.
  • Controlled Pollution .
  • Checking of effluents from vehicles.
  • DEFORESTATION: This term denotes the process of cutting trees ruthlessly. It simply means clearing the greenery in order to have industrialization or residential area. In addition to it has contributed in climate change but also proved to be a reason for loss of wildlife heritage.


  • Plantation of more and more trees. Most noteworthy, many schools have almost inculcated the habit of planting samplings on the eve of birthdays of students.
  • Acid Rain: Acid rain occurs due to the presence of certain pollutants in the atmosphere. This acidic fall is a known environmental problem that can have serious effect on human health, wildlife and aquatic species.
  • Waste disposal : The over consumption of resources and creation of plastics are creating a global crisis of waste disposal.Since plastics are non biodegradable, hence it rather gets basically stuck on the earth’s surface. Developed countries are notorious for producing an excessive amount of waste or garbage and dumping their waste in the oceans than less developed countries. Nuclear waste disposal most of all has tremendous health hazards associated with it. Plastic, fast food, packaging and cheap electronic wastes threaten the well-being of humans. Waste disposal is one of urgent current environmental problem.
Environmental Pollution

Environmental Pollution

  • Loss of Biodiversity:Human activities are leading to many unexpected results like extinction of species and habitats and loss of bio-diversity. Eco systems, which took millions of years to be perfect, is now in danger when a species population is decimating. Balance of natural processes like pollination is crucial for the survival of the Eco-system and human activity threatens the same. Furthermore, I remember of an example here. It is the destruction of coral reefs in the various oceans, which is vital for the rich marine life.

Garbage Pollution


  • Prohibition of Animal hunting or poaching.
  • Legally prohibiting the Use of animal skin for production of leather items or bags.
  • Reduction of Deforestation.
  • Better living environment to the wildlife either by continuously checking Water pollution.
  • If you love biodiversity and want to make everyone aware of it, then most importantly have a project on this topic and present it in your school.
