A search and rescue robot design based on LiDAR technology

For a long time, search and rescue operations during natural disasters and man-made catastrophes have been a major challenge. Due to the rapidly changing environment in disasters, deploying rescue teams for search missions entails significant risks. With advancements in technology, the latest innovations can be applied to search and rescue tasks to reduce these risks. LiDAR (Light Detection and Ranging) sensors can be installed on unmanned search and rescue vehicles to explore the space. This article utilizes solid-state LiDAR technology, along with various algorithms like SLAM (Simultaneous Localization and Mapping) and EKF (Extended Kalman Filter), to design a remotely controlled unmanned exploration vehicle. By capturing point cloud data, it enables modelling and recording of indoor or outdoor spaces, allowing for space exploration and the identification of trapped individuals and other important rescue-related information before rescue personnel enter the premises. This significantly reduces the risks and time involved in search and rescue operations. The prototype vehicle designed in this paper possesses the advantages of low cost and high flexibility, making it feasible for direct deployment after minor optimization. Finally, the author provides a summary and outlook for this research.

Design, Performance Analysis, and Experiments of a Soft Robot for Rescue

Abstract In the narrow and irregular environment of the ruins, the existing rescue robots are struggling to achieve their performance. Inspired by the process of termite predation by giant anteaters, we propose a soft rescue robot that utilizes motion propulsion similar to gear meshing and the adaptability of a continuum manipulator. The robot, consisting of a soft continuum manipulator and driving equipment, has the characteristics of fast propulsion and adaptation to unstructured environments. The driving device can give the manipulator a maximum speed of 14.67 cm/s and a propulsive force of 19.20 N. With the flexibility of the soft robot, the soft manipulator can adapt to the environment under propulsion to pass obstacles. The experiments of self-adaptability performance tests under different conditions show that the robot can pass over obstacles with an angle of up to 80.57 deg between its axis and the contact surface. In the actual ruin experiment, the robot could penetrate 1.3 m deep in the narrow passage formed by the bricks with the mode. The experiment indicates the presented rescue robot design's feasibility. Our work could contribute to the research on the interaction of soft robots with their environment.

Design, Analysis, and Experiment for Rescue Robot with Wheel-Legged Structure

A wheel-legged rescue robot design with strong environmental adaptability is proposed. The design presented is aimed at helping rescue workers complete their missions, such as environmental and personnel search, quickly and accurately. So it has broad application prospects. In order to achieve the advantages of simple structure, easy control, small occupation space, and wide motion range, a wheel-legged rescue robot is designed in this paper, and the robot can realize three kinds of motion states, which include wheel state, rotation center lifting process, and leg state. Then the motion states are analyzed in detail, which provides a reference for motion control. Considering the wheel state and leg state share the same structure to contact with the ground, the effect of the stiffness of wheel-legged structure to the motion performance is analyzed. Then the experiment is carried out to prove the feasibility of the structure design. This study offers a design and quantitative analysis for wheel-legged rescue robot. Furthermore, a basis for future control research and engineering applications is established.

Design of Rescue Robots with a Morphological Environment

The morphological environment, which models the human brain, is encouraged to be used by creating a mobile rescue robot. The use of such media will manage and organize large amounts of knowledge required for the design of new cars. Morphological environment should be of a certain structure, and to create new designs of machines it is reasonable to apply a special algorithm for the synthesis and improvement of existing machines and mechanisms using global and local performance criteria. An example of improving the design of mobile robot caterpillar engine is given in the paper.

Design and prototype of mobile robots for rescue operations

This study concerns the design and prototype of four different mobile robot platforms for rescue robot operations after an earthquake. At first, a test field is constructed to represent a mildly damaged earthquake zone. The test field consists of eight different sections: sand, gravel, ditch, water, bridge, incline, decline, and turn. The mechanical structure, electronics, software, communication, and possible sensory systems are explained. After the robots are manufactured, they are physically tested for their performance in the test field for 18 different parameters. The test results show the effective body structure. Challenges of the rescue robot design are explained and future expectations are given.

MEASURING TRUST OF HUMAN OPERATORS IN NEW GENERATION RESCUE ROBOTS

The utilization of mobile rescue robots in dynamic environments decreases the risk to emergency personnel in the field. Recent efforts to improve rescue robot design by using new fluid-power technology provide opportunities of studying the changes in metrics of human-robot interaction (HRI), such as trust. Trust is one of the most critical factors in urban search and rescue missions because it can impact the decisions human make in uncertain conditions. This research is to develop an instrument that can be used to measure trust in human-robotic interaction, which will allow us to collect data for building a quantitative model of trust in HRI. As the first step in this effort, a pilot study was conducted to determine the validity of an instrument to measure the appropriate dimensions of trust in this new human-robot system.

Rescue robots for mudslides: A descriptive study of the 2005 La Conchita mudslide response

AbstractThe Center for Robot‐Assisted Search and Rescue (CRASAR) assisted the Ventura County Fire Rescue Department with the January 2005 La Conchita, California, mudslide response. CRASAR provided commercially available urban search and rescue robots and expert operators which were deployed twice into damaged structures. The waterproof robots were able to tolerate wet conditions but proved unable to handle the densely packed rubble, vegetation, and soil and failed within two and four minutes, respectively on their two deployments. Informal interviews were conducted with responders as well. The experience forms a descriptive study of what mudslide responses are like, what tasks robots are needed for, how the rescue robots performed, and how responders viewed the robots. Our observations are captured in fourteen findings on robot performance (3), domain characteristics of mudslides (8), and general rescue robot design issues (3). These findings are expected to be of interest to robot designers, software developers, and the human‐robot interaction communities. The experience at La Conchita illustrates that terrain understanding, critical for both robot design and for control, remains an important open research question for rescue robotics. © 2008 Wiley Periodicals, Inc.

小型牽引ロボット群による姿勢変換作業について

We discuss a conceptual design of rescue robots against nuclear-power plant accidents. We claim that the rescue robots in nuclear-power plants should have the following properties. (1) The size is small. (2) The structure is simple. (3) The number of the robots is large. This paper studies the rescue robots to rescue people in an area polluted with radioactive leakage in nuclear power institutions. In particular, we propose a rescue system which consists of a group of small mobile robots. First, small traction robots set the posture of the fainted victims to carry easily, and carry them to the safety space with the mobile robots for the stretcher composition. In this paper, we describe the produced small traction robots. And, we confirm that the robots can manipulate a 40 kg dummy doll's posture. We also examine the optimal number of robots from a perspective of working efficiency in the assumption spot.
