Abstract
The pipe robots are autonomous machines that operate within pipe networks and perform several tasks including surveillance, monitoring, cleaning, rescue, etc., therein. Various elements, such as rust and fractures, could harm pipelines. Consequently, a reliable monitoring system is necessitated to guarantee the security of these pipes. It is difficult for an individual to examine each component of pipes and repair the problems. Pipe robots have been created as a result of such issues. Moreover, the demand for studies on pipe robots has increased in latest days. A variety of pipe robots are usable which include wheel type, screw type, wall-press type, walking type, inchworm type, etc. Relying on its specifications and assessment goal, every model has a unique set of benefits and drawbacks. This paper presents an overall review on the advancement of pipe robots from past few years. Authors believe that ongoing advancements in pipe robot technology are anticipated to be significantly influenced through this paper.
