    Leakage Detection in Water Pipes using a Smart Robotic Device

    , M.Sc. Thesis Sharif University of Technology Kazemi, Omid (Author) ; Sayyaadi, Hassan (Supervisor) ; Meghdari, Ali (Supervisor)
    Abstract
    Leakages in the transmission pipes include a large proportion of water loss. Scarcity of fresh water in one hand and high costs to compensate for drop in pressure and flow lines, on the other hand, detection and location of leaks have been important. This phenomenon can also cause a lot of damage to the urban contextures. This thesis considers the leakage in tubing buried in the soil by means of a floating robot. Since the rate of leakage, specifies the requirement to perform maintenances, In addition to finding the leakage, an overall estimate of the amount of leakage is desired.Since non-destructive leak detection is desired, the mechanical-magnetic sensor is designed. First, for the...

    Abstract
    Robotic blimps have a wide range of applications, such as monitoring activities in their surroundings, advertising, and performing on stages. They also have remarkable capacities to be used as a social robot. In this research, a manually operated social robotic blimp has been developed intending to interact with children as a social agent and attract adults’ attention as an entertainer in indoor public environments. Since the appearance of a social robot has a significant impact on its acceptance, first, we acquired opinions of several participants on the shape of a desired floating robot. The results revealed that a simple spherical structure adequately draws people’s attention. After...
