How to Design a robotic arm using Pneumatic?

what are the basic requirements to design a pneumatic based robotic arm ? will it work smoothly & efficiently than hydraulic based arm ?i would also want to know how pneumatic arm work??

  • Sep 8 2012: Check out publications like "Machine Design Magazine", "Design News", and "Design World".

    Air is a fluid like hydraulics, but it can be released in the atmosphere, so you do not need a return line. Pressure are typically much less than hydraulics.
  • Sep 5 2012: The main driver factors on robotic design are overall cost, performance and reliability.
    Evaluate the application, their requirements, your resources and the project timeline.

    Servo motors are the best on robotic industry but are costly.

    Pneumatics is more convenient, lightweight, powerfull and cheaper but noisy, unprecise and less controllable.

    Hydrailycs is more expensive due to the high pressure, more than servo, prone to leakage, less flexible and is mostly used in heavyweight lifting.

    Some companies are using pneumatic-servo combinations to reduce cost.

    For most applications you can use a pneumatic cylinder coupled to a graphite rod that can give enough positioning resolution and precision for many applications. I can also recommend strain sensors in case you need better control.
    You can also make very good programming, cheap and with few components using Microchip PIC series on a free PIC C compiller you can find on the internet.

    Consider the dynamic inertia, process cycling and components reliability in your design.
