According to Bame and Cummings, authors of Exploring Technology, total automation occurs when a process is completed without human control. A process rarely occurs without any human control at all. Usually some human control is involved. Automation is automatic control. As Avila (May 2002) developed an AS2 automatic sprayer (an innovation). The answer for more effective and much convenient spraying.
The main component used is same with the manual garden sprayer. There are some additional materials used to complete the project. AS2 automatic sprayer was developed to lessen the stress of the user in pumping the sprayer to create the pressure. It has an ability to pump in an automatically and when it reached the highest operating procedure, it will shut off and resume pumping when the pressure drops at the lowest operating pressure.
The sprayer has safety relief valve and emergency stop switch. It can refill solvent without releasing the pressurized air inside the sprayer. It can be carried by backpack or by using a trolley. When a factory, assembly line, or some process is automated, machine are used in place of human labor. Parts are moved on assembly lines. A work-piece—work being manufactured—is fed into a machine automatically. Work is done on the piece, and it is moved to another machine. All this is done without human intervention. Automation makes work easier and faster. One reason Soriano (March 2003) developed a printed circuit board-etching machine, which intends to make the etching process faster and easier.
The agitating machine is detachable wherein you can replace the basin corresponding to the size of your PCB (Printed Circuit Board). It has a timer where you can set at approximately five minutes and 38 sec. It has also a buzzer and light emitting diode (LED) that indicates that it has finished the desired time. It has an adjustable holder that allows the use of different size of PCB. It operates horizontally towards the basin and allows the vertical action of the PCB towards the ferric chloride during the etching process. Agitating machine provides not only convenience to users but also saves time, effort, money, space and energy.
Another way of describing automation is by saying it is automatic regulation. Automation is important to human technology. It undoubtedly will be important in the future. Automation can be found in nearly all areas of technology. Our first thoughts about automation may be of automated assembly lines with robots doing the work of humans. But, actually, automation can be found more often in other areas.
The machining of metal was among the first processes to be mechanized and then automated. Machine tools were first controlled by punched tape. There was no feedback. The tape merely controlled the location and cutting action of the cutter. These machines are called numerically-controlled (NC) machines. Each hole (or combination of holes) in the represent the command to the machine. Sensors detect the holes. A message is sent to the controls on the machine causing it to move in a certain way. Magnetic tape similar to that use in tape recorders replaced most punched-tape in NC machines.
Today computers control these automated machines. This is called Computer Numerical Control (CNC). CNC machines can store and transmit large quantities of very complex information. They are capable of doing very complicated tasks.
