TL;DR: In this article, an independent robot for in-pipe investigation is presented, which can detect the leakage of Methane, Butane, LPG, and Smoke in a pipe by moving horizontally and vertically to prevent mishaps in industries.
Abstract: Energy resources such as gas often transported through pipes which play a significant role in cities, industries Gas leakage in pipes prompts misfortune just as a danger since they can likewise prompt flame mishaps The point of this work is to structure an independent robot for in-pipe investigation The system utilized includes a focal pole whereupon a translational component is fitted which thusly is associated with three edges of connections and wheels DC motors are joined to the wheels to accomplish the drive required The component considers little settlement in-pipe distances across Setting sensors on each segment of pipe is in all respects exorbitant A pipe crawling robot prototype that can detect the leakage of Methane, Butane, LPG, Smoke in a pipe by moving horizontally and vertically to prevent mishaps in industries The Internet of Things (IoT) module is interfaced with a robot to give a real-time analysis on the cloud platform and GPS to give the exact location of the leakage

15 Mar 2018TL;DR: A new solution which controls some home appliances like light, fan, door cartons, energy consumption, and level of the Gas cylinder using various sensors like LM35, IR sensors, LDR module, Node MCU ESP8266, and Arduino UNO is developed and explained as a working model.
Abstract: In recent years, the advancements in Information and Communication Technology (ICT) are mainly focused on the Internet of Things (IoT). In a real-world scenario, IoT based services improve the domestic environment and are used in various applications. Home automation based IoT is versatile and popular applications. In home automation, all home appliances are networked together and able to operate without human involvement. Home automation gives a significant change in humans life which gives smart operating of home appliances. This motivated us to develop a new solution which controls some home appliances like light, fan, door cartons, energy consumption, and level of the Gas cylinder using various sensors like LM35, IR sensors, LDR module, Node MCU ESP8266, and Arduino UNO. The proposed solution uses the sensor and detects the presence or absence of a human object in the housework accordingly. Our solution also provides information about the energy consumed by the house owner regularly in the form of message. Also, it checks, the level of gas in the gas cylinder if it reaches lesser than the threshold, it automatically books the gas and sends a reference number as a message to the house owner. The proposed solution is deployed and tested for various conditions. Finally, in this paper, the working model of our proposed solution is developed as a prototype and explained as a working model.

TL;DR: The strategy and the critical points established on using the speed modulation for the navigation in elbows and branches for MRINSPECT (Multifunctional Robotic crawler for INpipe inSPECTion) IV are presented.
Abstract: In the previous reports (2001), we presented a miniature inpipe robot called MRINSPECT (Multifunctional Robotic crawler for INpipe inSPECTion) IV which has been developed for the inspection of urban gas pipelines with a nominal 4-inch inside diameter Its steering capability with three-dimensional differentially driven method provides the outstanding mobility for navigation and the new mechanism for steering can easily adjust itself to most of pipelines or fitting, in which other former inpipe robots can hardly travel as ever In this paper, we present the strategy and the critical points established on using the speed modulation for the navigation in elbows and branches The analysis for the navigation inside fittings and curved pipelines is given in detail and it is addressed how to compute the speeds of the independent wheels for the differential drive in elbows and branches

TL;DR: A compact, compliant external pipe-crawling robot that can inspect a closely spaced bundle of pipes in hazardous environments and areas that are inaccessible to humans is designed and tested.
Abstract: The focus of this paper is on the practical aspects of design, prototyping, and testing of a compact, compliant external pipe-crawling robot that can inspect a closely spaced bundle of pipes in hazardous environments and areas that are inaccessible to humans. The robot consists of two radially deployable compliant ring actuators that are attached to each other along the longitudinal axis of the pipe by a bidirectional linear actuator. The robot imitates the motion of an inchworm. The novel aspect of the compliant ring actuator is a spring-steel compliant mechanism that converts circumferential motion to radial motion of its multiple gripping pads. Circumferential motion to ring actuators is provided by two shape memory alloy (SMA) wires that are guided by insulating rollers. The design of the compliant mechanism is derived from a radially deployable mechanism. A unique feature of the design is that the compliant mechanism provides the necessary kinematic function within the limited annular space around the pipe and serves as the bias spring for the SMA wires. The robot has a control circuit that sequentially activates the SMA wires and the linear actuator; it also controls the crawling speed. The robot has been fabricated, tested, and automated. Its crawling speed is about 45 mm/min, and the weight is about 150 g. It fits within an annular space of a radial span of 15 mm to crawl on a pipe of 60-mm outer diameter.

TL;DR: In this article, a mobile feeder pipe inspection robot that can minimize the irradiation dose to human workers by automating the measurement process is described, which is a well known degradation mechanism called a FAC (Flow Assisted Corrosion).
Abstract: The outlet feeder pipe thinning in a PHWR (Pressurized Heavy Water Reactor) is caused by a high pressure steam flow inside the pipe, which is a well known degradation mechanism called a FAC (Flow Assisted Corrosion). In order to monitor the degradation, the thickness of the outlet bends close to the exit of the pressure tube should be measured and analyzed at every official overhaul. This paper describes a mobile feeder pipe inspection robot that can minimize the irradiation dose to human workers by automating the measurement process. The robot can move by itself on the feeder pipe by using an inch worm mechanism, which is constructed by two gripper bodies that can fix the robot body on to the pipe, one extendable and contractible actuator, and a rotation actuator connected to the two gripper bodies to move forward and backward, and to rotate in a circumferential direction.
