Deployment Of Robot Arms With A Leader-Follower Approach For Bomb Disposal

<div>Improvised Explosive Devices (IEDs) have been developed over the years across many nations around the world. IEDs used by terrorist actions and in warfare cause devastating death, injuries and damage. To protect the public, many emergency responders have to risk their lives by performing extremely hazardous tasks such as interacting with suspected IEDs. To prevent the emergency response teams from being negatively impacted by IEDs, many different kinds of response robots have been deployed in many locations worldwide – allowing first responders a safe way to interact with these menaces from a distance. This thesis contributes to the understanding of using robot arms with a Leader–Follower (LF) approach to help humans with performing dexterous operations like those which are inevitably required for manipulating IEDs remotely. The LF approach allows operators to remotely manipulate a robot arm without putting operators’ lives in danger. By physically controlling one arm from a safe distance, operators can successfully copy its movements to a second arm. As a result, we argue, this approach can be helpful for minimizing operator risk when interacting with suspicious devices while at the same time facilitating more intuitive remote control.</div>

PROTECTION OF CRITICAL INFRASTRUCTURE FROM EMERGING THREATS

Today's society is in a continuous transformation towards a digitalized society. The COVID-19 pandemic has accelerated worldwide the transition from the physical to the online environment of services provided by both public and private institutions. With a digitized society in our defense types of risks, threats and risks to critical infrastructures that support digital evolution. Thus, opponents turn their attention to new forms of asymmetric attacks to generate states of terror against states or individuals or groups of people. Thus, among the newest and most developed threats are those that use cyberterrorism, network-based warfare or attacks using technologies imported from the military such as drones carrying improvised explosive devices. Countermeasures and resilient systems must be prepared against them.

Design of a High-Power UWB Antenna Incorporating a Solid Dielectric for Electronic Warfare Applications

In this paper, a high-power ultrawideband antenna is presented for the purpose of remotely neutralizing improvised explosive devices. The developed antenna has a bandwidth between 230 MHz and 2 GHz, as well as a maximum realized gain of 18.7 dB. The antenna structure incorporates a solid dielectric (HDPE 1000) so that it can be powered, without risk of a possible breakdown voltage, by a Marx generator which delivers a bipolar pulse with a peak amplitude of +/−250 kV, a rise time of 170 ps, and a duration of 1 ns. The radiated electric field obtained in simulation is, respectively, 1 MV/m peak and 126 kV/m peak at a distance of 1 m and 10 m.

Design and Analysis of Vehicle Mine Blast Using AUTODYN

Anti-vehicular (AV) mines are capable of disabling a heavy vehicle, or completely destroying a lighter vehicle. The most common form of AV mine is the blast mine, which uses a large amount of explosive to directly damage the target. In a conventional military setting, landmines are used as a defensive force-multiplier and to restrict the movements of the opposing force. They are relatively cheap to purchase and easy to acquire, hence landmines are also potent weapons in the insurgents’ armamentarium. The stand-off nature of its design has allowed insurgents to cause significant injuries to security forces in current conflicts with little personal risk. As a result, AV mines and improvised explosive devices (IEDs) have become the most common cause of death and injury to Coalition and local security forces operation. A number of different strategies are required to mitigate the blast effects of an explosion. Primary blast effects can be reduced by increasing the standoff distance between the seat of the explosion and the crew compartment. Enhancement of armour on the base of the vehicle, as well as improvements in personal protection can prevent penetration of fragments. Mitigating tertiary effects can be achieved by altering the vehicle geometry and structure, increasing vehicle mass, as well as developing new strategies to reduce the transfer of the impulse through the vehicle to the occupants. Protection from thermal injury can be provided by incorporating fire resistant materials into the vehicle and in personal clothing. The challenge for the vehicle designer is the incorporation of these protective measures within an operationally effective platform.

Dangers Related to the Use of Improvised Explosive Devices On Terrorist Attacks - Experiences and Recommendations

This publication describes dangers of acts of terrorism using improvised explosive devices. The basic concepts concerning the main topic were explained and selected examples of terrorist attacks were presented. Publica-tion presents a description, statistics of use, construction and types of improvised explosive devices. Finally, a proposal of reducing human losses, counterterrorism and diagnosing dangers in the future is also presented.
