A novel capsule pipeline transportation system using a linear synchronous motor, called Magplane MagPipe, is under development with the intention to replace trucks and railways for hauling materials from the mine to the rail head, power plant or processing plant with reduced operating cost and energy consumption. The initial demonstration of a MagPipe line in Inner Mongolia will be a 500 meter ...

This paper proposes an in pipe inspection robot with the wall-pressing force adjustment using DC motor. It is developed for long distance inspection in sea-water pipelines such as horizontal pipelines and slope pipelines with large variable diameters from 600mm to 800mm. Its mechanical design consists of two modules as driving module and control module. The driving module has three pantograph t...

Pipe robots can perform inspection tasks to alleviate the damage caused by the pipe problems. Usually, the pipe robots carry batteries or use a power cable draining power from a vehicle that has many equipments for exploration. Nevertheless, the energy is limited for the whole inspection task and cannot keep the inspection time too long. In this paper, we use the total input energy as the cost ...

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...

In this paper, we describe the vision system for the DeWaLoP (Developing Water Loss Prevention) robot. The robot working environment is inside a pipe (a cylinder), which fits perfectly to the vision system, based on omni-directional cameras. By unrolling the omni-directional camera image to a panoramic image, the circular features of the pipe become linear and by adding a line tracking algorith...

The heat pipe as one of the most efficient exchanger device is used in many thermal engineering applications. Through sufficient literature research and summary, a comprehensive systematic analysis application cooling technology motor provided. basic principles key technologies introduced. What’s more, various factors affecting efficiency pipes two main types applications are discussed. Finally...

We present a pipe inspection robot using a newly developed spherical ultrasonic motor (SUSM) as a camera actuator. The novel SUSM has improved the range of movement compared to previous SUSMs, and the robot can point a camera in any direction. In this study, we determined a method for controlling the rotational direction and strategic control from the kinematics and characteristics of ultrasoni...

A direct-drive stepping motor, based on a new principle is reported. The features of the motor is (1) big torque (4-20 times bigger than that of the same-sized conventional electric motors), (2) high stepping resolution, (3) light weight, and (4) simple structure. The motors are suitable for robots in new applications such as microrobots and human-care robots. First, the mechanism and theoretic...
