The branch of technology that deals with the design, construction, operation, and application of robots.

A Short History of Robots

Robot Timeline:

  • ~270BC an ancient Greek engineer named Ctesibus made organs and water clocks with movable figures.
  • 1818 – Mary Shelley wrote “Frankenstein” which was about a frightening artificial life form created by Dr. Frankenstein.
  • 1921 – The term “robot” was first used in a play called “R.U.R.” or “Rossum’s Universal Robots” by the Czech writer Karel Capek. The plot was simple: man makes robot then robot kills man!
  • 1941 – Science fiction writer Isaac Asimov first used the word “robotics” to describe the technology of robots and predicted the rise of a powerful robot industry.
  • 1942 – Asimov wrote “Runaround”, a story about robots which contained the “Three Laws of Robotics”:
    • A robot may not injure a human, or, through inaction, allow a human being to come to harm.
    • A robot must obey the orders 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 within the First or Second Law.
  • 1948 – “Cybernetics”, an influence on artificial intelligence research was published by Norbert Wiener
  • 1956 – George Devol and Joseph Engel berger formed the world’s first robot company.
  • 1959 – Computer-assisted manufacturing was demonstrated at the Servomechanisms Lab at MIT.
  • 1961 – The first industrial robot was online in a General Motors automobile factory in New Jersey. It was called UNIMATE.
  • 1963 – The first artificial robotic arm to be controlled by a computer was designed. The Rancho Arm was designed as a tool for the handicapped and it’s six joints gave it the flexibility of a human arm.
  • 1965 – DENDRAL was the first expert system or program designed to execute the accumulated knowledge of subject experts.
  • 1968 – The octopus-like Tentacle Arm was developed by Marvin Minsky.
  • 1969 – The Stanford Arm was the first electrically powered, computer-controlled robot arm.
  • 1970 – Shakey was introduced as the first mobile robot controlled by artificial intellence. It was produced by SRI International.
  • 1974 – A robotic arm (the Silver Arm) that performed small-parts assembly using feedback from touch and pressure sensors was designed.
  • 1979 – The Standford Cart crossed a chair-filled room without human assistance. The cart had a tv camera mounted on a rail which took pictures from multiple angles and relayed them to a computer. The computer analyzed the distance between the cart and the obstacles.

Advantages and disadvantages of robotics


  • You can send them to very dangerous places
  • You can make them do you’re job for you
  • They are more accurate than humans Eg no shaking when in a very important surgery, puts every screw in fabricating a car etc.
  • Can do jobs 24/7
  • Can guard without being tired just keep doing the same thing 24/7
  • No need of nutrients
  • You can programme them to make them do exactly what you want them to do
  • They cannot harm you unless they are programmed to
  • Can work without doubts Eg when you think “what do i do now”?
  • They can lift very heavy things


  • You need to get people trained to fix them if anything wrong happens
  • Need a very intelligent crew
  • They can ruin people lives Eg Take their job away from them
  • They are very expensive to make
  • You need the right materials to make them, that could be very rare
  • If you make a very amazing robot with amazing quality and it brakes, it might be very hard to fix
  • They can be very hard to program.
  • They can reproduce but it could cost money for the materials
  • You need highly trained people to make them
  • They cannot recharge themselves
