Robots are increasingly used in various industries and universities are actively involved in this field to promote the technology among the undergraduates. This work deals with the development of a laboratory-scale pipeline inspection robot that is based on LEGO Mindstorms for a faster mobility in horizontal pipeline. It employs color sensors to detect the cracks that are represented by different types of color tapes. Communication between two NXT bricks - MASTER and SLAVE through Bluetooth connection has been established for real-time data transmission. Data storage is done by transferring it from MASTER to PC browser. This robot could be used for laboratory experiments at undergraduate level teaching.
