Robotics

For the most part, the word "Robot" today means any man-made machine that can perform work or other actions normally performed by humans. But even before that the Greeks made movable statues that were the beginnings of what we would call robots. The word "robot' was coined by Karel Capek who wrote a play entitled "R.U.R." or "Rossum's Universal Robots" back in 1921. The base for this word comes from the Czech word 'robota' or 'robotnik' which means work, forced labor, servitude, or drudgery. In his play, machines modeled after humans had great power but without common human failings. In the end these machines were used for war and eventually turned against their human creators. Most robots today are used in factories to build products such as cars and electronics. Others are used to explore underwater and even on other planets.

The main components of Robots
Robots have 3 main components:

• Brain - usually a computer
• Actuators and mechanical parts - motors, pistons, grippers, wheels, gears
• Sensors - vision, sound, temperature, motion, light, touch, etc.

With these three components, robots can interact and affect their environment to become useful.

3 Laws Of Robotics
Popular science fiction writer Isaac Asimov created the Three Laws of Robotics:
#1 A robot must not injure a human being or, through inaction, allow a human being to come to harm.
#2 A robot must always obey orders given to it by a human being, except where it would conflict with the first law.
#3 A robot must protect it's own existence, except where it would conflict with the first or second law.

The Impact Of Robotics On Society
Since robots are used mainly in manufacturing, we see their impact in the products we use every day. Usually this results in a cheaper product. Robots are also used in cases where it can do a better job than a human such as surgery where high precision is a benefit. And, robots are used in exploration in dangerous places such as in volcano which allows us to learn without endangering ourselves.

Problems With Robotics
As with any machine, robots can break and even cause disaster. They are powerful machines that we allow to control certain things. When something goes wrong, terrible things can happen. Luckily, this is rare because robotic systems are designed with many safety features that limit the harm they can do.
There's also the problem of evil people using robots for evil purposes. This is true today with other forms of technology such as weapons, and biological material.
Of course, robots could be used in future wars. This could be good or bad. If humans perform their aggressive acts by sending machines out to fight other machines, that would be better than sending humans out to fight other humans. Teams of robots could be used to defend a country against attacks while limiting human casualties. Could future wars really just be a video game that drives robots? Either way, human nature is the flawed component that's here to stay.

Job Displacement
Some people are concerned that robots will reduce the number of jobs and kick people out of their jobs. This is almost never the case with new technology. The net affect of advanced technology such as robots (or cars, electric drills, copying machines) is that humans become more productive.

Advantages Of Robotics
The advantages are obvious - robots can do things we humans just don't want to do, and usually do it cheaper. Also, robots can do unsafe jobs like monitor a nuclear power plant or explore a volcano. Robots can do things more precise than humans and allow progress in medical science and other useful advances. Robots are especially good at boring, repetitive tasks such as making circuit boards or dispensing glue on parts.

The Future Of Robotics
The population of robots is growing rapidly. This growth is lead by Japan that has almost twice as many robots as the USA. All estimates suggest that robots will play an ever-increasing role in modern society. They will continue to be used in tasks where danger, repetition, cost, and precision prevents humans from performing.
