Our crawler is largely divided into three units: the robot body, vertical elevation lift unit, and wheel frame unit.
Each of these three units is independently modularized and can be connected to each other by connecting cables. These units can create various shapes and sizes of robots in infinite combinations when combined and used with Spherical-Cell Extension Kit (SEK).

When photographing a large box-shaped pipeline, or an egg-shaped pipeline, or even in a large gradient, in all of these cases, our expansion and transformation solutions of RoboCrawler S provide outstanding results.

The four kinds of wheels, which can cope with various diameter sizes of pipelines, can be easily replaced by using our one-touch method.

RoboCrawler S is a single standard model that can inspect at a minimum of 8-inch (200mm) up to 50-inch (1250mm) diameters when used with an extension kit (CCB or SEK).
Also, if a separate mini crawler is used, small pipes of 5-inch (125mm) to 10-inch (300mm) diameter can be inspected as well.

This means suggests that these two units can carry out inspection services in most of the pipelines in which the users would want to inspect. There is a clear difference between RoboCrawler S and other brand products, because users would have to purchase at least three units individually and pay a much higher price.

 The RoboCrawler S is designed with a double chamber seal structure with Q-ring, completely defending it from external water that can damage the axis of the rotating wheels. The existing products, in the box-shaped structure waterproofing mechanism, get damaged immediately after water penetrated it. Our RoboCrawler S has an oil fence inside the wheel frame unit, which fundamentally prevents the robot from being damaged by external water.
Nevertheless, if water gets in,  a warning message is sent to the control monitor and a warning sound is used to prevent major damage.

Our state-of-the-art invention WAW (Worm and Worm Wheel) Lift Unit is a structural design that cannot be found in any competitor’s product.
WAW can remotely adjust the height of the camera. It has a structural principle in which the camera orbits around a large circular gear that does not revolve

just like how satellites orbit 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 camera is moved by an external force,

the gear will not get damaged, nor will it get broken. The units that assemble these parts of the tractor can also

be easily replaced and repaired by users simply 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 robot itself.
The camera head lift unit and the PCB Pack, which is the inner part of the robot body can also be conveniently replaced by users.
