A self-growing robot with an aerodynamic drag reducing endoscope
By using a self-growing robot with a dual-chamber design, the friction between the endoscope and the robot body is reduced by utilizing the air pressure cavity, which solves the problem of poor endoscope synchronization and achieves high synchronization rate, low resistance and accurate delivery, which is suitable for complex path detection.

AI Technical Summary
During the extension process of the self-growing robot, the friction between the endoscope and the internal channel of the robot leads to poor synchronization and large frictional drag, which may cause the endoscope to elongate more than the robot body, thereby damaging structural stability, increasing driving resistance, or even jamming.
The system employs a dual-chamber design. The main chamber provides the driving force, while the drag-reducing chamber injects gas into the space between the endoscope and the inner surface of the robot body through a support pipe to form a pneumatic cavity. This reduces the contact area, achieves pneumatic lubrication, and lowers friction.
This technology enables precise synchronous growth of the endoscope and the robot body, reducing friction, ensuring the stability and success rate of the detection mission, preventing the endoscope from getting stuck, and reducing manufacturing and maintenance costs.
