Force-Feedback and Time Delay
The ability to carry out delicate manipulations relies greatly upon feedback. For example it is easy to learn how much pressure is required to handle an egg. In robotic surgery, surgeons need to be able to perceive the amount of force being applied without directly touching the surgical tools. Systems known as force-feedback, or Haptic technology, have been developed to simulate this. Haptics is the science of touch. Any type of Haptic feedback provides a responsive force in opposition to the touch of the hand. Haptic technology in telesurgery, making a virtual image of a patient or incision, would allow a surgeon to see what they are working on as well as feel it. This technology is designed to give a surgeon the ability to feel tendons and muscles as if it was actually the patient’s body. However these systems are very sensitive to time-delays such as those present in the networks used in remote surgery.

Famous quotes containing the words time and/or delay:
“In a time of confusion and rapid change like the present, when terms are continually turning inside out and the names of things hardly keep their meaning from day to day, it’s not possible to write two honest paragraphs without stopping to take crossbearings on every one of the abstractions that were so well ranged in ornate marble niches in the minds of our fathers.”
—John Dos Passos (1896–1970)
“Face troubles from their birth, for ‘tis too late to cure
When long delay has given the evil strength.
Haste then; postpone not to the coming hour: tomorrow
He’ll be less ready who’s not ready now.”
—Ovid (Publius Ovidius Naso)
