Abstract: The present disclosure relates to a robotic system for respiratory diagnosis and treatment and a control method therefor. The present disclosure includes a master control apparatus for operating and controlling a control instruction, a slave control apparatus for receiving the control instruction of the master control apparatus and operating an operation action, and a navigation apparatus for guiding the slave control apparatus. The slave control apparatus includes a slave robot and a slave embedded controller installed inside the slave robot. The slave robot is provided with a mechanical arm, a propulsion support plate connected to the mechanical arm, a biopsy instrument introduction mechanism connected to a propulsion support plate for delivering a biopsy instrument, a bronchoscope rotation driving mechanism for controlling a bronchoscope, and a bending control mechanism for controlling an angle of a flexible end of the bronchoscope.
