Pneumatics

From FIRSTwiki

Pneumatics  is a system in which pressurized gases (air in the case of FIRST), are used to move actuators such as cylinders or rotary actuators.

Components

• Cylinders
• Solenoids
• Compressor
• Storage tank(s)
• Rotary actuator
• Pressure regulators
• Pressure switch

Advantages

• Natural linear motion (doesn't need to be converted from rotational motion) making interfacing with structure simple
• Very high forces possible without any mechanical reduction

Disadvantages

• Large initial weight cost
  • Compressor
  • Storage tank(s)
• Routing hoses can be difficult
• Total power/energy output is less than that achievable with motors
• Frequent use will drop air pressure faster than the compressor can raise it, resulting in a severe performance drop.
