A Human-Animal-Robot Cooperative System for Anti-Personal Mine Detection InTech
Thrishantha Nanayakkara; Tharindu Dissanayake; Prasanna Mahipala; K. A. Gayan Sanjaya.
To the best of the author's knowledge, this is the first time a human-robot-animal integrated system is tested for antipersonnel landmine detection. The proposed system tries to integrate distinct capabilities of three different systems to improve the effectiveness of landmine detection in a cluttered environment. The mongoose is found to be a rodent with extremely sensitive olfactory capabilities, dexterous navigation capabilities in a cluttered environment, and small enough to burrow through rubble. The lightweight legged robot (4kg) can move in a minefield without detonating landmines, carry a metal detector, and interact with the mongoose and the human. The remote human operator can analyze the behaviors of the animal-robot system and judge how best...

Development of Deminer-Assisting Robotic Tools at Tokyo Institute of Technology InTech
Marc Freese; Paulo Debenest; Edwardo F. Fukushima; Shigeo Hirose.
Gryphon and Mine Hand are complementary tools; while the former was developed to efficiently search for buried landmines, the latter one is meant to be used once a suspect spot was found to assist and protect deminers in the landmine neutralization task. Gryphon and Mine Hand, more than just research prototypes, were conceived from the beginning on to be practical and well integrated systems. Minefields are no laboratories; working conditions are extremely varied and far from ideal, requiring robust systems, and based on the invaluable experience acquired during field tests, trials and discussions with deminers themselves, Gryphon and Mine Hand were continuously improved to come closer to practical and useful tools for humanitarian demining.

Developments on an Affordable Robotic System for Humanitarian Demining InTech
Pedro Santana; Luis Correia; Jose Barata.
This chapter presented some guidelines to build a portable demining kit, which is intended to be a fast deployable and affordable robotic system to aid in emergency situations. Since the logistics of a portable demining kit are less demanding when compared to a regular demining campaign, local mine action centres, provided with such a tool, will be able to be more responsive to emergency situations, reducing the chances of further victims. It has been shown that to be successful, these kits must also be self-sustainable. This ranges from requiring simple maintenance, to the fact that they should be usable in other domains. If that is the case, then the owners, local governments for example, can exploit the devices for other purposes. Several aspects of a...

Humanitarian Demining: the Problem, Difficulties, Priorities, Demining Technology and the Challenge for Robotics InTech
Maki K. Habib.
The major technical challenge facing the detection of individual mine lies on having the ability to discriminate landmines from metal debris, natural clutters, and other objects without the need for vegetation cutting. Future efforts to improve detection should focus on providing discrimination capabilities that includes the fusion of information coming from multi heterogeneous and/or homogenous sensors, and the incorporation of advanced signal processing techniques to support real-time processing and decision making. For the purpose of mine clearance, there is an urgent need to have cost-effective and efficient clearance techniques and technologies to clear landmines in different types of terrain and under different climate variations. This should be...

Humanitarian Demining Using an Insect Based Chemical Unmanned Aerial Vehicle InTech
Sergi Bermudez i Badia; Paul F.M.J. Verschure.
In this project we investigated the use of a chemo-sensing Unmanned Aerial Vehicle (cUAV) for humanitarian demining tasks. In this chapter we have shown a wide spectrum of developments oriented towards the autonomous and non-supervised mine detection on large scale and unspecified environments by means of a blimp-based chemo-sensing UAV equipped with a broadly tuned metal thin oxide chemo-sensor. These developments include the design and construction of a number of indoor robots (mobile and flying robots), the first outdoor chemo-sensing UAV, novel insect based flight control methods and a number of moth based localization strategies. The central assumption of our work is that we can develop advanced and effective demining systems by basing them on insect...

Land Robotic Vehicles for Demining InTech
Stefan Havlik.
Considering large polluted areas and drawbacks of actual demining technologies main contributions of using robotic vehicles are expected in following topics: - Searching large areas and localization of mines and any explosives (UXO) by fast and reliable way. - Fast and reliable neutralization/destruction of mines without the need of personal assistance to be inside, or close to dangerous places. Demining process remains and will be still one of the most dangerous operations. For this reason new robotic technologies and detection principles should be applied. The paper presents a modular concept and on examples describes the robotic vehicles equipped by the flailing activation mechanism and other accessories used in demining process and other civil...

Mine-suspected Area Reduction Using Aerial and Satellite Images InTech
Acheroy Marc; Yvinec Yann.
This Chapter concentrates on the mine action technology problem and more specifically on the description of the processing algorithms used in the SMART project on area reduction. Nevertheless, the SMART approach has its limitations. The general knowledge used in SMART is strongly context-dependent. It has been currently derived from the study of three different test sites in Croatia chosen to be representative of South-East of Europe. In the case of another context a new field campaign is needed in order to derive and implement new

Multi-sensor Data Fusion Based on Belief Functions and Possibility Theory: Close Range Antipersonnel Mine Detection and Remote Sensing Mined Area Reduction InTech
Nada Milisavljevic; Isabelle Bloch; Marc Acheroy.
Several fusion methods for close range humanitarian mine detection and remote sensing mined area reduction are presented and compared. These methods are based on the belief functions as well as on the fuzzy/possibility theory. Regarding close range mine detection, the differences at the combination step are mainly highlighted in this comparison. The modeling step is performed according to the semantics of each framework, but the designed functions are as similar as possible, so as to enhance the combination step. Different fusion operators are tested, depending on the information and its characteristics. An appropriate modeling of the data along with their combination in a possibilistic framework leads to a better differentiation between mines and friendly...

Power Tillers for Demining in Sri Lanka: Participatory Design of Low-cost Technology InTech
Cepolina Emanuela Elisa.
Considering the increasing consensus on the fact that mine action should be regarded as a development activity, there should be rapid change of the current approach. The paper summarises few topics in the domain and introduces a new integrated approach to the design of simpleffective demining technologies. The methodology is applied to the design of a simple modular machine for assisting mine removal through ground processing and vegetation cutting. The tractor unit is chosen in the agricultural machines domain (power tillers), so that to assure the full consistency with the local expertise and habits. Cost and sophistication minimisation is primary objective of the present project. The machine is equipped with a pneumatic remote control, versatile enough...

Vehicle Mounted Dual Sensor: SAR-GPR InTech
Motoyuki Sato; Kazunori Takahashi; Takao Kobayashi Jun Fujiwara; Xuan Feng.
SAR-GPR, which is an array GPR sensor unit, which is to be used on an unmanned vehicle MHV was developed by Tohoku University. It is equipped with 3 VNAs, and has 3 pairs of Vivaldi antenna. The operation frequency of the system can be selected between 100MHz4GHz, dependent on the soil characteristics. Signal processing including CMP and migration is applied to the acquired GPR signal, and they reduce the clutter and can image the buried targets. Then SAR-GPR has been tested in test sites in Japan, the Netherlands and Croatia. In any cases, SAR-GPR could provide clear images of buried landmines, when the ground has relatively flat surface. Since the SAR-GPR has 10cm offset above the ground surface, it can separate the reflection image of the ground surface...
