The invention relates to a
robot for collecting pharyngeal flor, the
robot comprises a head fixing and positioning mechanism, a
variable stiffness mechanism, a mechanical arm and a sampling table. When pharyngeal
flora is collected, a lead screw mechanism in a head fixing and positioning mechanism in the
robot can be adjusted according to the size of the head of a to-be-detected person, the effect of fixing the head of the to-be-detected person is achieved, after head positioning is completed, a
detector follows a designed technical
route, through control by a controller, the
tail end of the pharyngeal
flora collection robot can realize a motion path similar to that of manual collection to complete collection of pharyngeal
flora; a
variable stiffness mechanism is adopted, hard contact between the
tail end of the pharyngeal flora collection robot and the
pharynx of a to-be-detected person is avoided, meanwhile, a head fixing and positioning mechanism is composed of a parallel mechanism and a lead screw, good supporting performance and adaptability are provided, and the robot is suitable for wide
crowds; when the tester operates the robot, the designed technical
route is followed, the accuracy of collected samples is high through accurate control, and an accurate result can be obtained through detection.
