Robots present an opportunity to go where rescuers cannot, keep responders out of danger, work indefatigably, and augment the capabilities of the humans who put their lives at risk while helping others. This paper examines the use of robotic systems in human rescue applications, with an emphasis on performing search, extraction, evacuation, and medical field treatment procedures. The work begins with a review of the various robotic systems designed to perform one or more of the above operations. The relative merits of each system are discussed along with their shortcomings. The paper also addresses the use of robotic competitions as a means of benchmarking field robotic systems. Based on the review of state of the art systems, a novel concept (Semi- Autonomous Victim Extraction Robot) designed to address the shortcomings of existing systems is described in the conclusion, along with detailed discussion on how it improves upon state of the art systems. The future research thrusts to be explored before realizing a fully integrated robotic rescue system are also detailed.

    Design of a Low-Cost, Highly Mobile Urban Search and Rescue Robot Bradley E. Bishop * Frederick L. Crabbe Bryan M. Hudock United States Naval Academy 105 Maryland Ave (Stop 14a) Annapolis, MD 21402 [email protected] Keywords: Rescue Robotics, Mobile Robotics, Locomotion, Physical Simulation, Genetic Algorithms Abstract— In this paper, we discuss the design of a novel robotic platform for Urban Search and Rescue (USAR). The system developed possesses unique mobility capabilities based on a new adjustable compliance mechanism and overall locomotive morphology. The main facets of this work involve the morphological concepts, initial design and construction of a prototype vehicle, and a physical simulation to be used for developing controllers for semi-autonomous (supervisory) operation. I. INTRODUCTION Recovering survivors from a collapsed building has proven to be one of the more daunting challenges that face rescue workers in today’s world. Survivors trapped in a rubble pile generally have 48 hours before they will succumb to dehydration and the elements [1]. Unfortunately, the environment of urban search and rescue (USAR) does not lend itself to speedy reconnaissance or retrieval. The terrain is extremely unstable and the spaces for exploration are often irregular in nature and very confined. Though these challenges often make human rescue efforts deep within the rubble pile prohibitive, a robot designed for urban search and rescue would be very well suited to the problem. Robots have already proven their worth in urban search and rescue, most notably in the aftermath of the September 11 th , 2001 disaster.

    Engineering International, Volume 2, No 1 (2014) Asian Business Consortium | EI Page 20 Engineering International, Volume 2, No 1 (2014) Multipurpose Tactical Robot Md. Taher-Uz-Zaman1, Md. Sazzad Ahmed2, Shabbir Hossain3, Shakhawat Hossain4, & G. R. Ahmed Jamal5 1,2,3,4Department of Electrical & Electronic Engineering, University of Asia Pacific, Bangladesh 5Assistant Professor, Dept. of Electrical & Electronic Engineering, University of Asia Pacific, Bangladesh ABSTRACT This paper presents a general framework for planning a multipurpose robot which can be used in multiple fields (both civil and military). The framework shows the assembly of multiple sensors, mechanical arm, live video streaming and high range remote control and so on in a single robot. The planning problem is one of five fundamental challenges to the development of a real robotic system able to serve both purposes related to military and civil like live surveillance(both auto and manual), rescuing under natural disaster aftermath, firefighting, object picking, hazard like ignition, volatile gas detection, exploring underground mine or even terrestrial exploration. Each of the four other areas – hardware design, programming, controlling and artificial intelligence are also discussed. Key words: Robotics, Artificial intelligence, Arduino, Survelience, Mechanical arm, Multi sensoring INTRODUCTION There are so many robots developed based on line follower, obstacle avoider, robotic arm, wireless controlled robot and so on. Most of them are built on the basis of a specific single function. For example a mechanical arm only can pick an object inside its reach. But what will happen if the object is out of its reach? Besides implementing a simple AI (e.g. line following, obstacle or edge detection) is more or less easy but that does not serve any human need.

  • Enhancing Geometric Maps Through Environmental Interactions
    Enhancing geometric maps through environmental interactions SERGIO S. CACCAMO Doctoral Thesis Stockholm, Sweden 2018 Robotics, Perception and Learning School of Electrical Engineering and Computer Science TRITA-EECS-AVL-2018:26 KTH Royal Institute of Technology ISBN 978-91-7729-720-8 SE-100 44 Stockholm, Sweden Copyright © 2018 by Sergio S. Caccamo except where otherwise stated. Tryck: Universitetsservice US-AB 2018 iii Abstract The deployment of rescue robots in real operations is becoming increasingly com- mon thanks to recent advances in AI technologies and high performance hardware. Rescue robots can now operate for extended period of time, cover wider areas and process larger amounts of sensory information making them considerably more useful during real life threatening situations, including both natural or man-made disasters. In this thesis we present results of our research which focuses on investigating ways of enhancing visual perception for Unmanned Ground Vehicles (UGVs) through environmental interactions using different sensory systems, such as tactile sensors and wireless receivers. We argue that a geometric representation of the robot surroundings built upon vi- sion data only, may not suffice in overcoming challenging scenarios, and show that robot interactions with the environment can provide a rich layer of new information that needs to be suitably represented and merged into the cognitive world model. Visual perception for mobile ground vehicles is one of the fundamental problems in rescue robotics. Phenomena such as rain, fog, darkness, dust, smoke and fire heav- ily influence the performance of visual sensors, and often result in highly noisy data, leading to unreliable or incomplete maps. We address this problem through a collection of studies and structure the thesis as fol- low: Firstly, we give an overview of the Search & Rescue (SAR) robotics field, and discuss scenarios, hardware and related scientific questions.

Law Zero: A robot may not injure humanity, or, through inaction, allow humanity to come to harm. Law One: A robot may not injure a human being, or, through inaction, allow a human being to come to harm, unless this would violate a higher order law. Law Two: A robot must obey orders given it by human beings, except where such orders would conflict with a higher order law.

Most of current human-tracking methods are targeted for mobile/tracked robots, but few of them can be used for legged robots. Two novel human-tracking strategies, view priority strategy and distance priority strategy, are proposed specially for legged robots, which enable them to track humans in various complex terrains. View priority strategy focuses on keeping humans in its view angle arrange with priority, while its counterpart, distance priority strategy, focuses on keeping human at a reasonable distance with priority. To evaluate these strategies, two indexes(average and minimum tracking capability) are defined. With the help of these indexes, the view priority strategy shows advantages compared with distance priority strategy. The optimization is done in terms of these indexes, which let the robot has maximum tracking capability. The simulation results show that the robot can track humans with different curves like square, circular, sine and screw paths. Two novel control strategies are proposed which specially concerning legged robot characteristics to solve human tracking problems more efficiently in rescue circumstances.

Consider the multi sensor platform that the USAR UGV is equipped with, protecting the sensors from the danger that dwells in the working environments is highly related to the success of the USAR mission. The radioactive working environments due to the diffusion of the radioactive materials during the decommissioning of the nuclear facilities are proposed in this work. Radiation shielding boards are used to protect the sensors by installing them on the UGV. Generally, the more shielding boards installed on the UGV, the lower the probability of the sensor malfunctioning. With a large number of UGVs that are used in missions, a large number of shielding boards are needed. Considering the cost of the boards, a conflict between the finite budget and the best protection for the UGV swarm occurs.
