(ROV) Pleco Water Tank Cleaning Robot

    Project Code: 150
    The invention presents a Remotely Operated Underwater Vehicle (ROV) to clean sediment that accumulates over time in water storage tanks. Water storage tank needs to be cleaned and free from bottom sediments. Conventional method of manual cleaning leads to problems such as water supply disruption, longer cleaning period, manpower intensive and costly.
Project Overview

Clean water supply is important in ensuring good health of people. Water supply is distributed from water storage tanks. Sediment that accumulates over time in water storage tanks will deteriorates the water quality used by consumers. Therefore, water storage tanks are required to be cleaned once in every three years by water utility operators or tank cleaning service providers.

Manual cleaning method is done by draining off and resupply water into the tank after workers have cleaned the tank using water jet and brushes. In this project, an alternative cleaning method using a Remotely Operated Underwater Vehicle (ROV) is proposed. By using ROV, water supply disruption can be prevented and cleaning process will be more efficient and cost effective. An ROV is built to operate underwater and vacuum out sediments from water tank. Live-streaming video and data feedbacks can be seen by operator on screen. Raspberry Pi is used as the main communication board to interface with MATLAB software. Operator will operates the ROV remotely to carry out the cleaning process.
