1. A method of operating a robotic surgical system comprising:
storing, by a processor of a computer device, a planned trajectory of a surgical instrument;
sequentially inserting a plurality of dilators through a patient skin for successively enlarging a surgical incision to access a vertebra of the patient, wherein the last inserted dilator defines a working channel for accessing the vertebra;
removing all dilators while leaving the last inserted dilator with the largest circumference in place as a working dilator; and
after the removing step, rigidly attaching the working dilator and only the working dilator to an end effector of the robotic surgical system through a dilator fixation which is rigidly secured to a robot arm such that the robotic surgical system always knows the position of the dilator fixation;
repositioning the trajectory of the surgical instrument after the working dilator has been attached to the end effector.
