SURVEYING THE SECTOR
To identify weaknesses and potential problems in the pipework , inspection robots host a variety of technology onboard . Most common will be some kind of visual inspection system , such as a camera . A series of motors allow the camera to pan , tilt and focus , helping engineers to obtain a full 360-degree view of the pipe . Positioning sensors help the robot to navigate the bends and changing diameters within the pipe network .
Ultrasonic sensors can be added to measure wall thicknesses and identify pipe defects . Other options include adding drives for tool functions , such as the ability to carry sealants to fix small cracks or grinders to remove corrosion .
Driving success
The quality of the drive systems powering the inspection robot are integral to its success . The motors must be robust and be able to cope with harsh operating conditions , including temperature extremes , humidity and being partially or fully submerged in water . Response times must be short to ensure that the movement of the robot is coordinated with the operator ’ s camera feed .
The motors must also be capable of providing enough torque to move the robot through dirt or debris on the floor of the pipe , and able to work continuously for extended periods of time . And
