Automation engineers use electric motors, hydraulic and/or pneumatic devices and solenoids to operate their designs.
Single-acting devices consist of a large plunger, or piston, into which oil (or air in a pneumatic cylinder) is pumped.
Yes there is. Pneumatic valve springs. They are metal bellows that have air in them. Their use is in replacing metal wire springs in a high-speed combustion engine. An example would be formula one engines.
Companies in the fluid power cylinders and actuators industry manufacture hydraulic and pneumatic cylinders used in various devices, such as jacks, lifters, and machine tools.
Hydraulic system make use of hydraulic devices to perform a variety of functions.
Some actuator or devices are operated by compressed air. These devices are known as pneumatic components
hydraulic car lift and hydraulic tire changer
Pneumatic means pertaining to air. It is often used with reference to devices which work by using pressurised air as the motive force.

The question indicates a serious misunderstanding in the operations and physical make-up of a robotic device. Most modern robotic devices are simple machines that have been automated using a control mechanism such as a computer or microcontroller. The word "Urinate" indicates that a biological entity is passing urine, the byproduct of cellular activity. Robots are not biological in makeup, and as such do not pass urine. Some robots use hydraulic fluid to pressurize actuators, but most robotic devices use pneumatic or electrical actuators.
hydraulic systems
There are more than two hydraulic devices that an auto machanic is familiar with but one of the is the braking system of a car and the other is the automatic transmissions of a car.
