robotic arm

A robotic arm is a type of mechanical arm, usually programmable, with similar functions to a human arm; the arm may be the sum total of the mechanism or may be part of a more complex robot.

                   

Premise

·       An automatically operated hand that replaces human effort, though it may not look much like a human arm.

·       Advanced high-performance robotic arms are used today in automobile manufacturing and aircraft assembly, and electronics to sort or test finished products.

·       Designing, construction and fixing of automobiles may not be perfect when done by humans. So we can use robotic arms to do the work.

·       Robotic arms are also used in chocolate factories for packing the chocolates into their required cases.

·       Robotic arms can be used at houses as it may reduce our effort on work.

ANALYSIS

Robots are used in many fields and some of them are:

·       Vehicle and car factories,

·       Precision cutting, oxygen cutting, lasers, etc.,

·        Mounting circuits on electronic devices (i.e. mobile phones)

·       Working where there might be danger (i.e. nuclear leaks, bomb disposal)

·       Surgeons are performing robotic-assisted surgeries that, among other things, can equalize little

·       Jiggles and movements of a surgeon's hands when doing delicate procedures, such as microscopically aided surgery or brain surgery, etc.

·       Other manufacturing, such as certain repetitive steps in assembly lines or for painting products so humans don't breathe the over spray or have to work with respirators on, working in the heat of drying and treating ovens on wood products, etc.

·       Mail delivery to various mail stations throughout the buildings in large corporations. (They follow routes marked with ultra violet paint).

·       To assist police and SWAT teams in dangerous situations, such as with hostages or in shoot outs and stand offs. They can be sent to the scene to draw fire, open doors, "see" the environment from a closer view point, or look in windows with cameras, etc. 

·       Remote procedures by a surgeon or other doctor who is unable to be there to perform the surgery in person (such as at an ice-bound Antarctic research center) or where there is a shortage of surgeons in a specific specialty and the remote surgeon does or guides the procedure from far away via robotic "hands". 

·       Space

·       Toy (Playing ect.)

Robotic systems are used in a number of ways such as:
1) In manufacturing - To help make stuff, faster and with more  quality control;
2) In processing operations - fitted with cameras to sort foods quality;
3) In inaccessible areas - very small robots accessing places we can't go, or space exploration missions;
4) In dangerous areas - inside nuclear reactors to check them out;
5) In the military - to keep humans out of harms way;
6) In medical environments - helping surgeons perform operations;
7) To assist disabled people - with the use and control artificial limbs;
8) To help market their products - the Honda Robot, Vacuum Robot;
9) To find out what they are capable of doing - in universities and research organizations;
10) In toys - Very simple robotic techniques are used in toys for children.
Pretty much in my opinion they are there to do jobs, that we can't do, are not very good at doing (high precision, repetitive work) or don't want to do.
Almost anything. Anything you can build to do something for you is basically a robot. One definition of robot is "artificial agent"                                                      

These days most of the really popular robots are exploring places people can't go yet and doing things too dangerous for humans to do safely (like hunting for roadside bombs in war zones or searching the bottom of the ocean).
Nanotechnology is finally catching on, with motors and wheels the size of atoms.
