Pneumatics is a branch of engineering that deals with the use of compressed air to perform work. It involves systems that use air pressure to move or control machinery, making it essential in various applications, such as industrial automation and robotics. Pneumatic systems typically consist of components like compressors, valves, and actuators. These systems are favored for their simplicity, speed, and safety. Unlike hydraulic systems that use liquids, pneumatics relies on air, which is abundant and non-toxic. Common uses include pneumatic tools, such as drills and wrenches, as well as conveyor systems in factories, where they help in moving products efficiently.
