With the widespread use of low-dose computed tomography，the detection rate of peripheral pulmonary lesions（PPLs）is increasing year by year. Tissue biopsies of PPLs are required to obtain a pathological diagnosis. PPLs are far away from the central airway and close to the pleura，making it difficult to reach with conventional bronchoscopy，resulting in suboptimal diagnostic rates and sensitivity. Although percutaneous lung biopsy has improved diagnostic rates，it has a high rate of complications. Robotic - assisted bronchoscopy（RAB）is a new technology for the diagnosis of lung lesions，improving navigation accuracy，expanding the reach of the lens，and offering advantages of high accuracy，stability and flexibility，leading to higher diagnostic rate and safety compared to traditional bronchoscopy. RAB can also serve as an interventional platform combined with the existing ablation therapy for tumor ablation in the lungs. With continuous technological advancements，the application of RAB will become more widespread and represents the future trend in bronchoscopy development.
