The Encountered Problems and Solutions in the Development of Coal Mine Rescue Robot

Abstract

Based on the various problems in the process of coal robot applications, from three-dimensional analysis of the key technology, market demand, and policy regulations and standardization, the paper reviews the use of carbon fiber material, elastic material of traditional surface spraying and integral casting technology to realize lightweight robot, by using the dual redundant design to improve the reliability of the rescue robot CPU, through the functions of voice recognition obstacle sensor, gas sensor acquisition components, and distribution information to realize the underground rescue mission. In addition, virtual test technology, hardware in the loop simulation technology, and shrinkage model technology are proposed to solve the difficulties of hard field testing of rescue robots. These suggest that concrete measures have been pointed out to break the problem of the development of the coal mine relief robot.

Coal Mine Rescue Robots Based on Binocular Vision: A Review of the State of the Art

“…; the site information was transmitted to the rescue center through optical cables. However, it weighed more than 544 kilograms, so it was not very flexible [10]. The Ratler robot was designed by the Sandia National Laboratory and the MSHA in the United States.…”

“…To enable a CMRR to pass along the roadway smoothly, its structure should be compact and its size should be reduced as much as possible. For instance, the ANDROS Wolverine robot is large, and it is inconvenient to move along a roadway, so its rescue ability is not good [10]. Consequently, in the installation of the binocular camera, space limitations must be considered.…”

“…At present, most CMRRs are in the experimental research stage, and only a few CMRRs are involved in mine rescue. For instance, a CMRR from the Western Australia Water Service Company was allowed to participate in a search-andrescue after a mine accident at New Zealand's Pike River coal mine on November 19, 2010 [10]. As shown in Fig.…”

Robotics for Disaster Warning and Response in the UAE

“…A rescue robot is a robot that has been designed for the purpose of rescuing people or facilitating rescue missions which can be in several modes, shapes or formats. For instance, robotic water rescue system, which is a four-foot, 25-pound remote-controlled robot, used as a hybrid flotation buoy-lifeboat called the EMILY (Emergency Integrated Lifesaving Lanyard) was co-developed by the U.S. Office of Naval Research, and Hydronalix an Arizona based company [17]. In 2016, during the European migrant crisis, the robot was used to rescue hundreds of asylum seekers off the coast of Greece.…”

“…Three robots were deployed following the accident, but they were all destroyed following a second explosion. A few months after, the Western Australia Water Service Company succeeded in getting video data of the mine's roadway, to help the police to determine whether the mine can enter the recovery stage [17].…”
