Anitha meets her friends and shares her experience of a robot expo.

அனிதா தன் நண்பர்களை சந்தித்து, ஒரு ரோபோ கண்காட்சி அனுபவத்தைப் பகிர்ந்து கொள்கிறாள்.

Friends : Hi, you look excited. Anything special?

நண்பர்கள் : ஹாய்! நீ உற்சாகத்துடன் காட்சியளிக்கிறாய். ஏதேனும் விசேஷமா?

Anitha : Yes! I went to the ‘ROBOT EXPO’ yesterday. I was so excited seeing all the robots.

அனிதா : ஆம்! நேற்று நான் ரோபோ கண்காட்சிக்குச் சென்றிருந்தேன். எல்லா ரோபோக்களையும் பார்த்து நான் உற்சாகமாகிவிட்டேன்.

Friends : Tell us more!

நண்பர்கள் : அதைப் பற்றி மேலும் சொல்!

Anitha : A humanoid welcomed me into the hall.

அனிதா : ஒரு மனித உருவ ரோபோ என்னை ஹாலுக்குள் வரவேற்றது

Friends : What is that?

நண்பர்கள் : என்ன அது?

Anitha : A robot that looks like a human. It even knew my name, I was so surprised and shocked that I stood there frozen.

அனிதா : மனிதனைப் போல காட்சிதரும் ரோபோ. அது என் பெயரைக்கூட அறிந்திருக்கிறது.அதிக ஆச்சர்யத்தாலும் அதிர்ச்சியாலும்நான் அங்கேய உறைந்து
நின்றுவிட்டேன்.

Friends : Wow!

நண்பர்கள் : வாவ்!

Anitha : I am just getting started. A robot just looked at me and named the things I had with me.

அனிதா : நான் இப்போதுதான் சொல்ல ஆரம்பித்திருக்கிறேன். ஒரு ரோபோ என்னைப் பார்த்துவிட்டு, நான் வைத்திருந்த பொருட்களின் பெயர்களைச்
சொல்ல ஆரம்பித்துவிட்டது.

Friends : Amazing, it must have scanned you with its eyes!

நண்பர்கள் : அற்புதம்! அதன் கண்க ளால் உன்னை நுட்பமாக அது சோதித்திருக்க வேண்டும்.

Anitha : The next robot danced for the songs played by the visitors. I suddenly found a butterfly sitting on my shoulder.To my surprise,it was a robot. There were robots of ants and fish too.

அனிதா : பார்வையாளர்கள் இசைத்த பாடல்களுக்கு ஏற்றபடி அடுத்த ரோபோ நடனமாடியது. ஒரு வண்ணத்துப்பூச்சி என் தோள்பட்டையில் வந்து அமர்ந்ததை நான் திடீரென கண்டேன். அது ஒரு ரோபோ என்பதுதான் ஒரு ஆச்சர்யம். எறும்புகளின் மற்றும் மீன்களின் ரோபோக்களும் அங்கு
இருந்தன.

Friends : An ant robot? Wow!

நண்பர்கள் : எறும்பு ரோபோவா? வாவ்!

Anitha : I saw a robot cooking dishes and serving all. It served me an omelette.

அனிதா : ஒரு ரோபோ உணவு வகைகளை சமைத்து பரிமாறியது. ஒரு ஆம்லேட்டை அது எனக்குப் பரிமாறயது.

Friends : Don’t we all wish for a ‘COOK ROBOT at home!

நண்பர்கள் : வீட்டில் சமையல்கார ரோபோ வேண்டுமென்று நாம் எல்லோரும் விரும்ப மாட்டோமா?

Anitha : Adding to my excitement, a robot collected and dropped an empty water bottle into the dustbin. Then, it advised all of us to use dustbin.

அனிதா : என் உற்சாகத்தை மேலும்அதிகரிக்கும்படியாக, ஒரு ரோபோ காலியான ஒரு தண்ணீர் பாட்டிலை எடுத்துச் சென்று, குப்பைத்தொட்டியில் போட்டது. பிறகு அது எங்கள் எல்லோரையும் பார்த்து குப்பைத் தொட்டியைபயன்படுத்தும்படி அறிவுரை தந்தது.

Anitha : Then there was a robot that asked me “Do you want to make a robot?” I eagerly nodded my head and said “Yes! But, I don’t know how to make it.” It replied, “Don’t worry. I will help you.”

அனிதா : பிறகு, ஒரு ரோபோஎன்னைப்பார்த்து,”நீ ஒரு ரோபோவை செய்ய விரும்புகிறாயா?” என கேட்டது. நான் ஆர்வத்துடன் தலையசைத்து, “ஆம்! ஆனால், அதை எப்படிச் – செய்வது என எனக்குத் தெரியாது”, என்றேன். “கவலைப்படாதே, நான் உனக்கு உதவுகிறேன்”, என்று அது பதில் கூறியது.
ரோபோ கண்காட்சி

Anitha : Then, it said “Let us make a robot that can run. There are three main parts in this robot. First is the controller it acts as the brain. Second is the mechanical parts that will help the robot move. Third is the sensors that will help the robot sense walls and other things on its way so that it does not crash into these objects. All these parts work together to make the robot run.”

அனிதா : பிறகு அது சொன்னது “ஓடக்கூடிய ஒரு ரோபோவை நாம் செய்யலாம்.ரோபோவில் மூன்று முக்கிய பாகங்கள் உள்ளன. முதலாவது
கன்ட்ரோலர். இது மூளைபோலசெயல்படும். இரண்டாவது மெக்கானிக்கல் பாகங்கள். இவை ரோபோ நகர்வதற்கு உதவும். மூன்றாவது சென்சார்கள். வழியில் உள்ள சுவர்கள், பொருட்களை உணர்ந்து, அவற்றின் மீது மோதிக் கொள்ளாமல் செல்ல உதவும். இம்மூன்று பாகங்களும் ஒன்றிணைந்து ஒரு ரோபோவைஓடச் செய்யும்.”

Anitha : Then, I put these 3 parts together with the robot and made a robot myself.This expo has made me really interested in robots.I am planning to make more robots. Will you all join me?

அனிதா : பிறகு, அதன் உதவியுடன் 3 பாகங்களையும் இணைத்து நானே ஒரு ரோபோவைச் செய்தேன். இந்த கண்காட்சி உண்மையில் எனக்கு ரோபோ மீதான ஆர்வத்தை ஏற்படுத்தியது. இன்னும் அதிக ரோபோக்களை செய்ய நான் ப திட்டமிட்டிருக்கிறேன். நீங்கள் என்னோடு சேர்ந்து கொள்வீர்களா?

Friends : We would love to!

நண்பர்கள் : நாங்கள் அதை விரும்புகிறோம்.

Voyage Summary in English and Tamil

The Horse and the Tiger, The Ape and the Goat, Decided one morning,To hire a boat.

குதிரையும் புலியும் குரங்கும் ஆடும் ஒருநாள் காலையில் தீர்மானித்தன, ஒரு படகை வாடகைக்கு எடுக்க.

To leave their own country, And find a new one, Very much in the manner, Columbus had done.

அவர்களின் சொந்த நாட்டை விட்டுச் சென்று ஒரு புதிய நாட்டை கண்டறிய,கொலம்பஸ் கண்டுபிடித்த அதே மாதிரி தாங்களும் கண்டுபிடிக்க.

The boat went a-sailing, Away and away, It sailed and they sailed, For a night and a day.

படகு பயணித்தது தொலைவான தொலை தூரத்திற்கு அது பயணித்தது, அவர்களும் பயணித்தனர்,இரவு பகலாக பயணம்.

When all of a sudden, There blew a great gale, The Horse was a-tremble,The Tiger grew pale.

அப்போது திடீரென்று ஒரு பயங்கர காற்று வீசியது குதிரை பயத்தால் நடுங்கியது புலியின் முகமும் வெளிறிப்போனது

The Ape and the Goat, Nearly fainted together, But the boat went a-sailing, In spite of bad weather.

அந்தக் குரங்கும் ஆடும் ஏறக்குறைய மயக்கம் போட்ட நிலைக்கு போயின | ஆனால் அந்தப்படகு பயணித்துக்கொண்டே இருந்தது,மோசமான வானிலை இருந்தபோதிலும்.

A-sailing, a-sailing, A-sailing it goes, To a wonderful country, Which nobody knows.

பயணித்து, பயணித்து பயணித்துக்கொண்டே அது சென்றது,ஒரு அழகான நாட்டிற்கு , யாருக்கும் தெரிந்திராத நாட்டிற்கு சென்றது.

The Horse and the Tiger, The Ape and the Goat, Has found a new one, As Columbus had done.

குதிரையும் புலியும்குரங்கும் ஆடும் ஒரு புதிய நாட்டைக் கண்டுபிடித்தன, கொலம்பஸ் செய்ததைப்போலவே.

Robinson Crusoe Summary in English and Tamil

Robinson Crusoe was a brave young man. He loved adventures. When he was nineteen years old, he left his home and took travel in the sea. One day, his ship started to sink because of a great storm. Robinson managed to swim to an island. When he reached the island, he was so tired that he just slept on the sand. When he woke up, he found a little dog next to him. They both were all alone in that place.

ராபின்சன் குருசோ ராபின்சன் குருசோ ஒரு தைரியமான இளைஞர். அவர் சாகசங்களைச் செய்வதில் விருப்பம் கொண்டார். அவருக்கு வயதான போது, அவர் வீட்டை விட்டுக் கிளம்பி, கடற்பயணம் மேற்கொண்டார். ஒருநாள் ஒரு பெரிய புயல் காரணமாக அவரது கப்பல் மூழ்கத் தொடங்கியது. ராபின்சன் நீந்திச் சென்று ஒரு தீவை அடைந்தார்.

இதனால் மிகவும் களைப்படைந்து அங்கு மணலின் மேலேயே படுத்து உறங்கிவிட்டார். அவர் விழித்து எழுந்தபோது, ஒரு நாய்க்குட்டி அவரது அருகில் இருப்பதைக் கண்டார். அந்த இடத்தில் அவர்கள் இருவரும் தனியாக இருந்தனர்.

Robinson explored the island, and he found the broken ship. He took some food, guns, clothing and tools from it. He made a tent and lived in it. He counted days on a wooden cross. From then on, he was able to keep a calendar. On the island, he found many kinds of goats and hares which he shot and ate.

ராபின்சன் அந்த தீவை ஆய்வு செய்து, அங்கு ஒரு உடைந்த கப்பலைக் கண்டார். அதிலிருந்து கொஞ்சம் உணவு, துப்பாக்கிகள், உடைகள் மற்றும் சில கருவிகளை எடுத்துக் கொண்டார். ஒரு கூடாரம் உண்டாக்கி அதில் வாழ்ந்தார். ஒரு மரச்சிலுவையில் அவர் நாட்களை குறித்துவைத்து வந்தார். அதன் பிறகு, ஒரு நாட்காட்டியை அவரால் பராமரிக்க முடிந்தது. அந்த தீவில் பலவகை ஆடுகளையும் முயல்களையும் அவர் கண்டு அவற்றை சுட்டு, சாப்பிட்டு வந்தார்.

Then, he made a small boat.

பிறகு, ஒரு சிறிய படகை அவர் தயாரித்தார்.

One day, Robinson found a footprint of a human, on the other side of the island. He was frightened. For two years he lived in fear. Then, one day he saw some tribal men chasing a young fellow. Robinson took out his gun and shot twice. The tribal men got scared and ran away. He named him Friday as he met him on Friday. At last, he had a human friend in the island. Robinson taught Friday to speak in English, to shoot and eat like a human.

ஒருநாள், தீவின் மற்றொருபக்கம் ஒரு மனிதனின் காலடிச்சுவட்டைக் கண்டார். அவர் பயந்துபோனார். இரண்டு ஆண்டுகள் பயத்துடன் வாழ்ந்தார். பிறகு, ஒருநாள் ஒரு இளைஞனை சில பழங்குடி மக்கள் துரத்திச் செல்வதை அவர் கண்டார். ராபின்சன் தன் துப்பாக்கியை எடுத்து இருமுறை சுட்டார்.

அந்த பழங்குடி மக்கள் பயந்து ஓடிவிட்டனர். அந்த இளைஞனை அவர் வெள்ளிக்கிழமை சந்தித்ததால், அவனுக்கு ஃப்ரை டே என பெயரிட்டார். கடைசியில், அந்தத் தீவில் மனித இனத்தைச் சேர்ந்த நண்பன் ஒருவன் அவருக்கு கிடைத்துவிட்டான். ஆங்கிலத்தில் பேசவும், துப்பாக்கியால் சுடவும், மனிதனைப்போல சாப்பிடவும், ஃப்ரைடேவுக்கு ராபின்சன் சொல்லிக்கொடுத்தார்.

One day, they both saved some people from the cannibals. Among them, they found Friday’s father and his friends. They stayed with Robinson and Friday for a few days and left the island. Another day, Friday informed Robinson about a ship. They both hid and watched the ship. Robinson learnt that the ship’s men had rebelled against the captain. After killing some of the rebels, Robinson, Friday and the captain retook the ship. At last, Robinson sailed from the island to England with Friday, after twenty-eight years, two months and nineteen days.

ஒருநாள், இருவரும் சேர்ந்து, நரமாமிசம் சாப்பிடும் ஆட்களிடமிருந்து சிலரைக் காப்பாற்றினார்கள். அவர்களிடையே ஃப்ரைடேவின் அப்பாவையும், அவரது நண்பர்களையும் அவர்கள் கண்டனர். அவர்கள் ராபின்சன் மற்றும் ஃப்ரைடே ஆகியோருடன் சில நாட்கள் தங்கிவிட்டு, தீவை விட்டு வெளியேறினர். மற்றொரு நாள், ஒரு கப்பலைப் பற்றி ஃப்ரைடே ராபின்சனுக்குத் தெரிவித்தான்.

அவர்கள் இருவரும் மறைந்திருந்து, அந்தக் கப்பலை கவனித்தார்கள். கப்பலின் கேப்டனை எதிர்த்து கப்பலின் ஆட்கள் கலவரம் செய்ததை ராபின்சன் அறிந்தார். கலகம் செய்த சிலரைக் கொன்றுவிட்டு, ராபின்சனும், ஃப்ரைடேவும், கேப்டனும் அந்தக் கப்பலை தங்களது கட்டுப்பாட்டுக்குள் கொண்டு வந்தனர். கடைசியில், 28 ஆண்டுகள் 2 மாதங்கள் 19 நாட்களுக்குப் பிறகு, ஃப்ரைடேவுடன் ராபின்சன் அந்தத் தீவிலிருந்து இங்கிலாந்துக்குப் பயணித்தார்.

The Trick Robot Summary in English and Tamil

Vicky was a lazy boy. He never did his homework on time. He never kept his things back in the right place. He pleaded to his father to buy him a robot to do his work. Vicky’s father wanted him to become an active boy. So, he bought him a trick robot. Vicky did not know that it was a trick robot. He was glad to have a robot to do all his work.

தந்திரசாலி ரோபோ  விக்கி ஒரு சோம்பேறி. ஒருபோதும் அவன் தன் வீட்டுப்பாடத்தை சரியான நேரத்திற்கு  செய்ததில்லை. எடுத்த பொருளை சரியான இடத்தில் அவன் திரும்ப வைத்தில்லை. தன்னுடைய வேலைகளையெல்லாம் செய்துதர ஒரு ரோபோவை வாங்கித்தரும்படி அவன் தன் அப்பாவிடம் கெஞ்சினான்.

அவன் ஒரு சுறுசுறுப்பான பையனாக வர வேண்டுமென அவனது அப்பா விரும்பினார். ஆகவே அவர் தந்திரசாலியான ஒரு ரோபோவை அவனுக்காக வாங்கினார். அது ஒரு தந்திரசாலி ரோபோ என்பது விக்கிக்கு தெரியாது. தன் வேலைகளை எல்லாம் செய்ய ஒரு ரோபோ கிடைத்ததை எண்ணி அவன் மகிழ்ச்சியடைந்தான்.

Father: Vicky, I have bought you a robot. This intelligent robot will do all your work. Enjoy!

தந்தை: விக்கி, நான் உனக்கு ஒரு ரோபோ வாங்கியிருக்கிறேன். இந்த புத்திசாலி ரோபோ உன் எல்லா வேலைகளையும் செய்யும்.

Vicky is excited to test his new robot.

அனுபவி! விக்கி தன் புதிய ரோபோவை சோதித்துப்பார்க்க ஆர்வப்பட்டான்.

Vicky: I am hungry. Cook some salad for me.

விக்கி: நான் பசியாக இருக்கிறேன். எனக்கு ஏதாவது கொஞ்சம் சாலட் செய்து கொடு.

Robot: I do not eat salad. So, I cannot make the salad.

ரோபோ: நான் சாலட் சாப்பிடுவதில்லை. ஆகவே என்னால் சாலட் செய்ய முடியாது.

Vicky: What? You are a robot. You cannot refuse me. Clean my room now!

விக்கி: என்ன? நீ ஒரு ரோபோ! நான் சொல்வதை நீ நிராகரிக்க முடியாது. இப்போது என் அறையை சுத்தம் செய்.

Robot: Do you want me to strain my back? I cannot do that.

  Changes in the physical features of the animal are called structural adaptations.
  Example: Polar bears Jiving in cold climate have physical adaptations, such as thick fur and short ears to reduce heat loss.
• Physiological adaptations:
  Changes in the functions of the animal’s body are called physiological adaptations.
  Example: Dog shivers to generate more heat when it is cold and pants when it is hot.
• Behavioural adaptations:
  Changes in the activities of the animal are behavioural adaptations.
  Example: Birds migrate to avoid adverse conditions.
