Why do we use robots?

Robots are machines that are intelligent enough to do important tasks for human beings. There are many science projects that depend thoroughly on the abilities of a robot to be successfully completed.

Robots are able to function in areas where human beings may find it difficult to. The best current example would be the Curiosity Rover on Mars. It is working in conditions that are inhospitable to humans and doing a commendable job of gather information from an unknown area.

There are some robots that are made to do dangerous jobs that can put human beings at risk. The R2 astro -robot on the International Space Center is one good example of this type of robot. R2 is being trained to work along with humans in space and to take on minor repairs on the outside of the space station, saving the human element space walks.

Some robots do not have a very inspiring job. They merely do a single task over and over again. The mindless repetition of the task may make it unsuitable for humans beings. Repetitive tasks make humans bored and careless and this can result in flaws that are best avoided. Most scientific experiments use some aspect of robotics.
