RoboCrawler S
Our main focus was to invent a sewer pipe inspection crawler that can transform into various shapes and sizes according to the users’ needs.
The strong driving performance and a completely submersible pipe inspection crawler allow users to use the equipment even in very rough and obstructive pipelines.
When photographing a large box-shaped pipeline, an egg-shaped pipeline, or even in a large gradient, in all of these cases, our expansion and transformation sewer inspection camera solutions of RoboCrawler S provide an outstanding effect.
The four kinds of wheels, which can cope with various diameter sizes of pipelines, can be easily replaced by the one-touch method.


Nevertheless, if water gets in, the control monitor is signaled by temperature and humidity sensors, and a warning sound is used to prevent a major failure.

This unit has a structural principle in which the camera orbits around the large circular gear that does not revolve, like how the satellite orbits around the earth.
This method allows a small motor to generate a large rotational force so that the camera can stably move in the vertical direction.
Even if the sewer camera gets moved by an external force, the gear will not be damaged, nor will it be broken.
The units that assemble these parts of the crawler can also be easily replaced and repaired by users on the spot.
For example, if the driving motor doesn’t work, then the users can easily replace the motor cylinder by loosening the two bolts without having to disassemble the sewer inspection crawler itself.
The camera head lift unit and the PCB Pack which is the inner part of the sewer pipe inspection crawler body can also be conveniently replaced by users.
