The Robocam S robot allows users to intuitively and easily change the size of the crawler. By changing the wheels to four different sizes or easily attaching a Giant Cradle Unit to the standard crawler with a few operations using a wheel adapter, the size can be adjusted to fit the diameter of the sewer pipe.

ROBOCAM S is a single standard model that can inspect at a minimum of 8-inch (200mm) up to 60-inch (1500mm) diameters when used with an extension kit (Giant Cradle) Also, if a separate mini crawler is used, small pipes of 5-inch (125mm) to 12-inch (300mm) diameter can be inspected as well.

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.
