Online meetings about sewer inspection camera, Robocam S.

We have online meetings at our office about once a month.


The location of these meetings varies from Singapore, Hong Kong, Indonesia, and the United States. Companies around the globe are very curious about our sewer inspection cameras. Clients want to know more about the inclination graph, the gyro sensor, and the center–positioning feature of our Robocam S model.


People often ask why are these three features important. The city pipeline network is laid out in many different ways, so this graph shows the angle of each pipe. There are 3 types of pipe slopes. A positive slope is angled in the right direction. This means water is flowing down the pipe toward the drain. A negative slope is angled in the wrong direction. The water in this pipe is flowing in the opposite direction of the drain. And, a no slope pipe has no direction for the water to flow. As time passes, pipes will shift, so the slope or grade of the pipes need to be checked from time to time.





There are 3 problems caused by misaligned pipes. And as time passes, the condition might worsen. First comes a sag, Second channeling, Third and fourth – separation, or breakage. A sag or belly happens when 2 pipes fall at the joint. And channeling is when water stays in a pipe. And finally, separation or breakage is caused, when the weight of the stagnant water in the pipe is too heavy for that section of the pipe. So proper alignment is very important for the health of your sewer system.


This inclination graph feature will evaluate the slope of every pipe in your network to determine the condition of the pipe network. This graph can be adjusted to produce a small graph (50 feet of data), or a large graph (100 feet of data). And the results can be seen in real-time on the controller monitor. A trucker will use the road signs on the mountain to determine the speed, gear, and braking style according to the grade of the slope, so we can similarly evaluate our robot.





The second feature of our S model is the gyro-sensor. A gyro-sensor or a gyro-meter is used to check for rotational motion or deviation from regular orientation. So it is like the balance in your ear lobe. Like riding in a car up a mountain, or riding the roller coaster at the amusement park; your ears will determine when you feel balanced and unbalanced.


An inspection robot going down these pipes might get in danger of tipping over, so this sensor gives you a warning. The warning light will go on if the crawler is tipping from side to side, or end over end. So these warning lights protect your equipment from getting seriously damaged.





Finally, the third feature of our crawler is for centering. Most governments require the inspection video to be taken in the middle of the pipe. Our infrared sensors on the side of the crown lamp detect the size of the pipe and adjust the height of the camera accordingly. For example – a right sensor indicates the distance to the edge of the pipe is 5 inches and a left sensor has the same measurement. Then, it determines the diameter of the pipe is 10 inches. So the robot camera is centered in the middle of the pipe according to these measurements.


This makes taking the inspection video according to the government regulations, an easy thing to do. So as you can see, all 3 of these features are very important for the sewer inspection business. Feel free to contact our office, if you would like to see and discuss the great features of our Robocam S.
