10. PNEUMATIC AUTOMATION Fluid comprises of liquids and gases, deforms on the application of shear stress . The technique that uses liquid for power transmission is called hydraulics while that using gas for the same is called pneumatics . The fluid system for power transmission obeys the fundamental Pascal’s law. For proper and reliable working of the hydraulic system the fluid ought to have the properties such as viscosity, oxidation resistance, pour and cloud point, flash and fire point, lubrication, heat generation and transmission, etc

15. Articulated Robots An articulated robot is a robot with rotary joints. Articulated robots can range from simple two-jointed structures to systems with 10 or more joints . They are powered by electric motors & are the most common type of robotic arm. It is used for assembly operations, die-casting, fettling machines , etc.
16. CONCLUSION Though, robotic automation has seen some of the most advanced and successful use of modern engineering , the demerits of this form of automation should also be considered. Unemployment, heavy initial cost & discouraging labour practices in countries with cheap labour are the negative impacts of automation. In most cases, the AI of automated systems are monitored by routine computer programs & do not operate depending upon all system variables. Having said that, the precision & speed of working with heavy equipments have greatly improved thanks to automation.
