Articulating arms are used within many different machines, from crane booms to the arms of a production plant robot. It is a technology that is widely adaptable and easilly automated, this is due to the unique design and the articulation of the arm function.
An articulating arm works much like a kunckle in a human finger. It consists of a joint between two different sections of the arm, which allows for a wide range of movement. This makes the arm very well sutied for detailed work applications such as computer chip construction or laser cutting.
If there is a disadvantage of using articulating arms, it is that they are highly specialised in this way. They often require precise programing for them to carry out seemingly simple jobs, and an operator who understands how to do this. However once automated the arms can peform the highly detailed work they are programed for with precision and consistency that is hard to find in any other technology.
