Abstract
An endoscopic robot (1), designed for being inserted into a body cavity (C)f a patient and advanced therein in a prefixed direction (A) with a so-called inchworm-like motion, comprising a variable length segment (2) and aspiration means (12, 13) for selectively producing a pneumatic vacuum (V) between the robot (1) and the body cavity (C) at the robot ends (3, 4) sufficient to produce a substantial anchorage to the body cavity walls, thereby allowing the inchworm-like motion and avoiding, at the same time, any pushing action against the body cavity walls which causes discomfort and pain to the patient.
