Definition of a Robot
A Robot is a reprogramable, multi-functional manipulator designed to move material, parts, tools, or a specialized devices through variable programmed motions for the performance of variety of tasks. In order to make a robot do anything it has to have a program or a set of programs that tell it to do certain tasks. Robots come in all different shapes and sizes. Some robots have been used to try and look and behave physically like a human being. Other robots are used for home entertainments. For example there is a robotic dog that now for sale that can behave and act like a dog. The nice thing about having a robotic dog is a person could shut it off when they get tired of it.
Different Kinds of Robots
Some robots have arms, legs, heads, wheels, and etc. There are robots that are used in big industrial factories. General Electric uses robotic arms to weld. The robotic arms can weld with such great precision that it looks perfect. There are also robots that have been used in movies such as Mighty Joe Young, Star Wars, and Jurrasic Park. Then there are also miniture robots that are designed like small insects such as horseflys and ladybugs. You can read about the insect robots in the National Geographics Magazine.
The Structure of the Robotic Hand
A robotic hand can be designed in different ways. The most important is that there is a wrist, fingers, and a way to move an object. The wrist will give the twisting motion. The fingers will be able to grab an object. Some people use grippers. The grippers work like sicorrs. There are also devices that act like sensory nerves. These devices are either light sensitive or switch activated. That way a robot would be able to tell where a light source is coming from or when it was running into a wall. The hardest part about making a robotic hand do something is to make the open and closing motion with the fingers. Humans have nerves and muscels that alow them to retract and contract their fingers. With a robot cables, motors, or pneumatic hydralics can be used. Strong cables can be used to give easy and quiet movements. Motors used with different gear ratios can make the fingers stronger when gripping or faster. By determining how much work would have to be done on the gear to make it spin would make the gear lift an object with force.
The first area that we see monumental change is in the ability for dexterous movement. The greatest development in this area is found in the Free-hand system developed by the Neuro-Control Corp. The January 1998 issue of FDA consumer outlines the workings of this system. First, the external Shoulder Position Sensor translates shoulder movements into electronic signals. The signals then travel to the External Controller for processing, and then to the external Transmitting Coil for relay to the Implanted Stimulator, which sends electrical stimulation along implanted Electrode Leads to implanted Electrodes in prosthetic hand, making them contract. With the use of this system amputees are again able to perform tasks were once impossible. The only problem with this system as pointed out in the September 13th issue of people magazine is that each unit costs about $50,000 an amount which most insurance companies are unwilling to fork out.
The most popular example of robotic arm is the Da Vinci Surgical System [4, 5] from Intuitive Surgical. This system is divided into four key elements.
I picked an article on the prosthetic limbs, which are controlled by your own thought. The unique part of this prosthetic is that It has 26 joints, is controlled by the person’s own mind and has the power to curl up to a incredible 45 pounds. Imagine being able to control a prosthetic just by thinking about the next move. The limb has been described as Modular, which gives them the power to accommodate anyone in particular that has either the hand missing to the whole entire arm. It can be also used as a surrogate arm for those who have suffered a stroke and lost movement of their own arm. This just an incredible part of science that getting develop and study by John Hopkins University.
Some would say the attempt to make a robot is an attempt to 'play god' and to recreate man. Others would argue that robots might become so intelligent that they would take over and replace humans. There is no better example of this than the movie Terminator, which begins with a world ruled by machines who are trying to kill the remaining human population. The actual field of robotics however, has produced many products which we take for granted. The clock is a household item that was developed in the beginning stages of machine ...
Robots are made out of metal, plastic, aluminum, gears, bolts, wheels, sensors, memory chips, and other gadgets.
...etrical size of the fingers form kind of like those of the fingers on the human hand. The Gifu hand Ⅱ encompasses an abundant higher variety of sensors and higher response than any antecedently developed robot hand, and may move additional quickly than the human hand. We have a tendency to think about that the Gifu hand Ⅱ is beneficial as a research tool for adroit robot manipulation mistreatment each force and tactile sensing.
The word “robot” was introduced in the beginning of 1920 by the Czech playwright Karel Capek from the Czech word “robota”, meaning “forced labor” (Robertson 2007, 373). According to Robertson (2007, 373), robot, in practical usage, can be defined as an autonomous or semiautonomous device that is used to perform its tasks either controlled by humans, fractionally controlled and with human guidance or regardless of external actions that are performed by people. Regrettably, the majority of robots in the past centuries could not operate without human control and intervention. However, the progress in robotics over the past few decades enabled humanity to achieve soaring results in the creation of autonomous humanoid robots. The purpose of this paper is to discuss the development of robotics science in modern society, its progress and future prospects, with specific reference to Japan.
It is a shared truth that humans often tend to think of robots as nothing more than computer machines made of objects like metal, plastic, silicone and computer chips. However, in truth, a robot’s general purpose is more complex than some know. In order for a robot to function, it must carry out a set of arithmetic or logical operations, and programming the specs is difficult task that could take years to finish depending on the purpose of the robot.
Design and implement a few haptic related projects for the benefit of physically challenged people. This proposal develops an approach for haptic exploration of unknown objects by robotic fingers. Because haptic exploration is coupled with manipulation and exploration using a sequence of phases is presented. With specialized fingers and sensors and appropriate planning and control robots can also be enabled to explore the worlds through touch. Haptic exploration has applications in many areas including planetary exploration, undersea salvage, operations in remote and hazardous conditions. Application of the human haptic interaction, multi sensory perception, action and multimodal feedback can be applied in the fields of education, rehabilitation, medicine, computer aided design, skill training, computer games, driver controls, simulation and visualization.
Scientific progress makes huge milestones toward developing new advanced technologies which are more and more present in human lives. Today robots replace people in many spheres such as health care, security and military, industry, education, entertainment and science. Role of robots becomes more significant because they are able to do the job which people are not able to perform well. Sometimes people are too lazy to do some routine work, due to such situation those tasks could be delegated to machines. People’s life become more technology based what makes demand for efficient robots larger. Engineers say that today robots look like machines, but in near future robots will have more human appearance, today they do some simple job, but in near future much more complicated tasks would be trusted to them. History of robotics goes far to the history when the ancient Greeks describes first devices that people were projected to fly to the sky like birds. In fact, heart of any robot is some program that direct the device and control it actions. Robot cannot perform the tasks that was not programmed in it and this if the factor what makes it quite limited in its actions. Current studies in robotics are aimed to remove those disadvantages and make robots more functional and universal through development of artificial intelligence that can operate independently. Curiosity of world community to robotics increase every day what make all the research and inventions in robotics more demanded. History of robots, resent achievement and future perspectives of robotics have to be studies and researched to understand what machines can give to humanity and what pros and cons exist in the r...
Robots are made to run without flaws and can outperform the average worker. This is because there are fewer employees working that need to get paid. This is not a good thing as it might seem. In China, robots almost completely replace human workers to save money.
...g to a bank to deposit a check, it can be done through a bank app on a smartphone or tablet where you take a picture of a check and it is deposited in your account. This app is unnecessary and we are able to do without it, but it saves time and money. Auto Mee S is a device that is now popular in Japan. It is a smartphone vacuum. This device was created to keep screens smudge-free. It replaces the traditional microfiber cloth. Time magazine released an excerpt talking about newly created robots. Japanese developers introduced a robot that can win at rock, paper, scissors. Brazilian students developed a Rubik’s Cube solver. Cornell and University of Chicago students collaborated and developed a dart thrower. These robots are all useless and there is really no need for them in society, it is just merely a source of entertainment, or just makes life that much easier.
I don’t think there is any reason for these robots to have every ability that a human does. There is no way they are going to have the intelligence a human does. Artificial Intelligence is just going to bring more harm into our communities. We can’t trust the robots doing the “everyday” human activities, they are going to lead to unemployment, and will lead to laziness causing more obesity.
The Robotics Industry Association defines a robot as ?a reprogrammable, multifunctional manipulator designed to move material, parts, tools, or specialized devices through variable programmed motions for the performance of a variety of tasks? (Zalda 8). In short, a robot is a machine that is programmed to perform a variety of tasks in place of humans.
Robots are one of the artificial intelligence that made a breakthrough across all fields of life. In consequence, many research studies and projects regarding robots took place in the last decade. In addition, robots in the society could be one of the essential machines, due to their multitask system which could adjusted to any kind of performance. In general society could use these machines to fill manpower gap in short time with less cost. Therefore, robots can have huge positive effects on different fields of life such as emergency situations, daily chores, and manufacturing industry.
