Basically, robots are designed in such way that they remove human intervention from labour intensive and hazardous work environment, sometimes they are also used to explore inaccessible work places which are generally impossible to access by humans. The coating of internal pipes comes in same category because they carry toxic chemicals, fluids and most of the time has small internal diameter or bends which become inaccessible to human. The complex internal geometry and hazard content constraints of pipes demand robots for coating of such pipes to prevent corrosion level of pipe, recovery of usable parts from pipe interior, sampling of sludge and scale formation on pipe internal surface etc. Several designs of In-pipe coating robots (IPCR) have been proposed in the literature to solve the problems related with of these complicated coating of internal geometries. Designing of an in pipe coating robot (IPCR) is a difficult task and hence the designer must take care of the design issues like Mobility, Steer ability,, Size and shape adaptability, Online adaptability, Flexibility, Stability, Autonomous operation and obstacle avoidance, Efficiency at uneven surface, Safe operation, Material selection, Type of task to be performed inside the pipe, Number of actuators, Operation in active pipe line, Retrieval of robot, User friendly navigation and control system, Range of operation, Quantitative analysis of defects inside the pipe. Based on above, research work presents investigations into design issues pertaining to development of In-pipe coating robotics and proposes a new model of an In-pipe coating robot to overcome some critical design issues. This proposed model is a screw driver type wall press adaptable wheeled In-pipe coating robot. It can move through vertical, horizontal pipes and it can easily pass through elbow of a pipe.
