ABSTRACT
This chapter discusses the functioning of robot-assisted systems and its advantages and disadvantages. Two devices exist and are both comprehensive master–slave robotic systems. Da Vinci evolved from telepresence machines developed for NASA and the US army. This system displays its three-dimensional image above the hands of the surgeon, thus giving him or her illusion that the tips of the instruments are an extension of the control grips, which in turn gives the impression of being at the surgical site. Zeus consists of a surgeon control console and three table-mounted robotic arms. The right and left robotic arms replicate the arms of the surgeon, and the third arm is a voice-controlled robotic endoscope for visualization. Robot-assisted surgery could potentially overcome many difficulties associated with laparoscopic surgery. The three-dimensional view with depth perception provides an improved view compared with the conventional laparoscopic camera views.
