  1. Actuators, Part II Fred Donelson Kevin McKone

  2. A second actuator that is often used is known as a solenoid

  3. It moves a rod by electromagnetic energy

  4. Click on the link below to learn the basics on how a solenoid works:http://www.youtube.com/watch?feature=endscreen&NR=1&v=hsoggQOoG4s

  5. Finally, we sometimes use the pressure of fluids to move objects

  6. When we use a gas as the fluid, we call it a pneumatics system

  7. When we use liquid as the fluid, we call it a hydraulics system

  8. Comparing Electrical and Fluid Actuators

  9. A simple hydraulic system can be made out of syringes and aquarium tubing

  10. A simple ROV with a hydraulic actuator

  11. Click the two links below to see some simple but effective hydraulic systems in action:http://www.youtube.com/watch?v=VFje0G69ku8&feature=relatedhttp://www.youtube.com/watch?feature=endscreen&v=vsF95qA1x7I&NR=1

  12. For ideas on building a linear actuator with a motor and some PVC, check out this link:http://blog.davidjbarnes.com/2009/03/making-linear-actuator-for-robots.html

  13. So … go have some fun and build yourself an actuator!!
