The presently available sewer inspection equipments based on CCD cameras have limitations and problems, as it requires the sewer lines to be drained. In this paper an automatic robotic sewer inspection equipment is proposed which uses ultrasonic sensors instead of CCD cameras. Hence it can work in water filled pipes without any need to drain it. Its working is controlled by embedded system. This can detect the blockage position and its type. The system can be further enhanced to clean the blockage also.
