Pipeline Inspection and Borewell Rescue Robot

The aim of this paper is to give an innovative concept to handle the bore well rescue operations without human intervention and to inspect any type of leakage in the pipe. Normal operation of child rescue is done by using big machines with large manpower involvement. It takes more time to rescue a child from the bore well and to check any kind of irregularities in pipe. Wheeled leg mechanism is employed in this design to go inside the pipe. The legs are circumferentially and symmetrically spaced out 120 o apart. The robot is made adaptive so that it can adjust its legs according to the pipeline dimensions. This structural design makes it possible to have the adaptation to the diameter of pipe and to have adjustable attractive force towards the walls of pipe. In this project, the condition of trapped child is captured with USB Camera and monitored on PC. LM-35 Temperature Sensor and 16X2 LCD are interfaced with PIC 16F877A microcontroller to sense the temperature inside the bore well and to display it respectively. The microcontroller stores the sensed data and displays it on the LCD. The robot structure consists of power supply, switch pad and gear motors. Adding a claw or gripper was the initial hurdle for which additional power supply and DC gear motor were needed. The microcontroller is not sufficient to give the sufficient amount of current to the multiple gear motors, so in spite of using motor driver, direct supply is given to gear motors using switch pad as its control centre enables the robot to work smoothly. The project is intended to reduce the risk involved during the child rescue operation by analyzing the situation and also to provide an option detect any leakage inside the pipe.
