Leaks are major problem that occur in the water pipelines all around the world. Several reports indicate loss of around 20 to 30 percent of water in the distribution of water through water pipe systems. Such loss of water represents critical waste of valuable resources, especially in countries such as Saudi Arabia where water is scarce. Moreover, leaks provide pathways for outside contaminants ...

Inspector Systems is a specialist in manufacturing of tethered self-propelled pipe robots for internal inspection, non-destructive testing and machining of pipeline systems. Our industrial sectors, which originates from 30 year experience in the nuclear industry, are Gas & Oil (On-/Offshore, Refineries), Chemical, Petrochemical, Water etc. The pipe robots are able to get inserted through poor a...

Liquid Natural Gas (LNG) processing facilities contain large complex networks of pipes of varying diameter and orientation intermixed with control valves, processes and sensors. Regular inspection of these pipes for corrosion, caused by impurities in the gas processing chain, is critical for safety. Popular existing non-destructive technologies that used for corrosion inspection in LNG pipes in...

The purpose of this research is to realize a small robot which can negotiate pipes whose diameter varies widely during the robot’s course. A new in-pipe locomotion mechanism named “snaking drive” is proposed in this paper and its potential and fundamental characteristics are shown with experimental data of the prototype model. First, in the sections 2 to 5, the basic traveling characteristics o...

The paper addresses the navigation problem for an autonomous robot designed to inspect sewerage. The robot, which is about half size of the sewer diameter, must keep its orientation in the entirely dark sewerage. The only a priory information known is the geometrical shape of the sewer (cylindrical, etc). This implies a strong geometrical constraint on the environment the robot can expect. In t...

In this paper, a piezoelectric microrobot is modelled and simulated based on active force control (AFC) with a proportional (P) – type iterative learning algorithm (ILA) operating in a constrained environment for an in-pipe application. A mathematical model that represents the dynamic characteristics of microrobot has been developed considering the robot system subjected to different input exci...

Now a days child often fall down in the borehole which is left uncovered and get trapped. It is very difficult and also risky to rescue the trapped children. A small delay in the rescue can cost the child his or her life. The objective of the project is to construct and design a bore well rescue robot (i:e to rescue a trapped baby from bore well). This project is a human controlled robot that g...

From teaching in labs to training for assembly, a key role that robots are expected to play is to instruct their users in completing physical tasks. While task instruction requires a wide range of capabilities, such as effective use of verbal and nonverbal language, a fundamental requirement for an instructional robot is to provide its students with task instructions in a way that maximizes the...
