ROBOTICS
When you think about the word robotics, the first words that probably come to mind are robots (duh), computers, science, design, operating, and programing. All of these answers are correct. The more specific term would be, “A branch of mechanical , electrical engineering that deals with the design, construction, operation, and application of robots, as well as computer systems for their control, sensory feedback, and information processing.” The word robotics was first used by Isaac Asimov, a famous sci-fi writer in 1941. A robot is considered any programmable device that performs certain tasks that we program it to do. In his story, Asimov describes three laws of robotics, that are still strongly taken into consideration today. These laws are:
1. A robot may not injure a human being or, allow a human being to come to harm.
2. A robot must obey the orders given to it by human beings, except orders that conflict with the First Law.
3. A robot must protect its own existence as long the method of protection does not conflict with the First or Second Law
Overall, robotics is basically the field of study pertaining to robots. When thinking of different examples of robots many people are probably thinking about R2D2 in Star Wars, the Terminator, or taking over the world. What is surprising is that robots are not only found in Hollywood movies, but also in our every day lives.
History of Robotics
The first description of a robot dates back all the way to the 3rd Century B.C in the Lie Zi text of mechanical engineer named Yan Shi. While not much is known about this robot, the description of his prototype was a life size human shaped figure. In 1495 Leonardo da Vinci designed a mechanical knight, humanoid robot. A more important break through was in 1898 Nikola Tesla demonstrated the first radio-controlled vessel, for the navy. In 1961 the first industrial robot was created by George Devol. From the turn of the century during the Industrial Revolution, the field of robotics exploded and rapidly advanced into what it is today.
Robots in the world:
Robots are used in jobs that are dangerous, boring, or inaccessible to humans. One of the main fields that robots are used in is in space exploration. NASA uses robots to navigate planets that humans can’t access easily. One of the most famous robots is called Curiosity. Curiosity was a rover designed and created by NASA to spend 2 years on Mars looking for signs of life. This rover is the size of a small car equipped with camera systems, and a radioisotope power generator. The rover has the ability to send back and analyze samples of materials collected to earth. Another example is Robonaut, a joint DARPA-NASA project. Robonaut is designed to function as a human would during space exploration.
Another huge area in which robots are used ins in industrial jobs. These robots are programed to quickly assemble things. Many of the robots in this field have the capability to operate alone or with some help to perform services useful to humans. Industries like Car production, packaging, and electronics. These jobs are repetitive an monotonous, that robots can complete without changing the quality of product, and getting bored or tired. Robots are also starting to be used to help educate us. I read an article called, Robots in the Classroom help Autistic Children Learn,” and it was about how humanoid robots were able to help autistic children in school. This is because robots have no emotion so autistic children find the robots less threatening and easier to communicate to them. Robots also teach us more about new possible scientific discoveries, like on other planets. Today, robots are being transformed into bionic prosthetics that are more advanced and human like. Robotic limbs have the capability to move in sync to the user’s movements. These prosthetics are connected to the persons central nervous system and as a result it is has the capability to recognize and coordinate the users intentions in different activities, and adjust. You will also find in dangerous war zones, robots like tele robots are used to help disable bombs and locate explosives.
Finally, Robots are being created to do fun, cool stuff. From breakdancing robots to robots that can perform laser point surgery there is a huge diversity. In todays society, people are working on new robots that would help us with our daily chores. Some example of those types of robots are the lawnbott (mows lawns for us), Stair a robot that can help with washing dishes and cooking meals. there are even robots that can be programed to be you’re own table tennis partner, and robots as simple as a golf bag that follows you. After researching all of these inventions, I couldn’t believe how many things that I thought were a fantasy were actually a reality!
Essential Characteristics of a Robot:
There are many types of robots, that are used to do different things. However, all robots share some basic similarities in construction:
1. Mechanical Construction: All robots have a frame, form, or shape designed for specific tasks. This construction determines the movement and sensing that the robot can do.
2. Electrical Components: Robots need a way to gain power and use the power to control the machinery. Electricity usually originates in a battery, or gas, then travels through wires to a circuit that sends electrical signals to operate the robot.
3. Computer Programing: The programming code determines when, how and what the robot should do. The program is the core essence of a robot, and is what makes the entire mechanism work. There are three main types of robotic programs:
Importance of Robotics:
Robotics have really helped benefit industries because they are able to achieve more profits, and less losses because products come out cleaner. Along with that, robots have created safer conditions in work places. Robots have also shaped our society in the entertainment industry. Also, as said above robots have helped us made huge discoveries that would have never been possible. Robots also have helped speed up medical treatments and more accurate surgeries.
Limitations and Negative Effects:
While robots are a positive thing in the world, they also can be a negative. The idea of artificial intelligence brings up a concern in many people, “What if robots become smarter and better than humans?” There is a possibility that these machines can become intelligent enough to operate independently and over throw the human race. Another down side is that robots are replacing humans in jobs, therefore increasing unemployment. The overall success and wealth due to robots is reaching a minority of people.
