Questions and Answers

What characterizes a voluntary-opening mechanism?

  • It is typically the lightest type of grasp device.
  • It operates similarly to a battery-powered device.
  • It remains open by default and closes with a pull.
  • It is held closed at rest and opens when the control cable is pulled. (correct)
  • Which statement about voluntary-closing mechanisms is true?

  • They require continuous power to function.
  • They usually tend to be heavier and less durable than their counterparts. (correct)
  • They are designed to be held open at rest.
  • They are generally lighter than voluntary-opening mechanisms.
  • Which of the following features distinguishes voluntary-opening mechanisms from voluntary-closing ones?

  • Voluntary-opening mechanisms open through a cable pull. (correct)
  • Voluntary-opening mechanisms can operate underwater.
  • Voluntary-opening mechanisms are actuated by battery power.
  • Voluntary-opening mechanisms are typically heavier.
  • In comparison to voluntary-closing mechanisms, voluntary-opening mechanisms are generally:

    Study Notes

    Active or Prehensors

    • Active grasp mechanisms can exhibit two distinct operational types based on how they function: voluntary-opening and voluntary-closing.

    Voluntary-Opening

    • Typically remains in a closed position at rest due to a spring or rubber band mechanism.
    • Activation occurs when a control cable is pulled, resulting in the device opening.

    Voluntary-Closing

    • Functions oppositely, operating by closing when activated.
    • Generally heavier and less durable compared to voluntary-opening mechanisms.
