Modelling and Analysis of Pipe Inspection Robot

Abstract

Abstract- Robots are used to remove human being from laborious and dangerous work. This project describes an inpipe inspection robot. This robot consist of a fore leg system, a rear leg system and a body. The fore and rear leg systems are constructed by using three worm gear system that are arranged at an angle of 120 degree with respect to each other to operate inside a pipe of different diameters. The springs are attached to each leg and the robot body to operate in pipes of 140mm to 200mm diameter range. Here, all major components of robot are designed. Modelling and assembly of robot components is done in Solidworks 11. Stress analysis of all major components is done in Solidworks 11 and Static stress analysis of proposed in-pipe inspection robot assembly is carried out in Ansys 13. This robot is used for offline visual inspection of gas pipelines, water pipelines and drain pipes etc. This robot also has wide applications in chemical industries as well as in gulf countries for inspection of oil and gas pipelines.
