Keywords: engineer robot, unmanned system, military engineering 1. Introduction Military engineering (MILENG) covers broad spectrum of activities – from combat to construction. Character and phase of the operation affect type of provided engineer support. Engineer tasks are usually very challenging and specialized. These types of tasks demand large quantity of time, forces, and assets and require special equipment [1]. Traditionally, MILENG tasks have been man power intensive, time-consuming, logistically demanding and dangerous [2]. What is more, military engineering and especially combat engineer tasks are frequently conducted in hostile environment with explosive hazard. But how to face this hazard when minimization of losses is always one of the main goals of deployed units in military campaigns? Heavy losses can affect deployed unit very negatively. Resistibility and force protection are extremely important in the sense of survivability and minimization of forces and means losses. One way of reducing risk to human life is to implement unmanned/robotic systems into military practise. Additionally, robots can reduce workload and save time. Robotic automation is inevitable process of human civilization development and modern armies react to this reality. Undoubtedly military robots and unmanned systems are becoming standard and common equipment of modern armies in recent 15 years. The process of robotic application interferes into all military areas and nor military engineering (MILENG) is exception. According to numerous studies, it is evident that application of unmanned technologies will have great impact on MILENG in the future, so we can predict that military robots will be integrated into Engineer corps as standard means of providing combat and general engineer support in military operations. 27 But a lot of questions is still unanswered. What are overall capabilities of these systems and what is their future? Do Engineers really need these systems? Will robotic systems push soldiers out of the battlefield in the future? This paper deals with these elementary questions and tries to find the answers. Main subject of this paper is to identify current state of implementation of robotic means into Czech engineer corps, to define their task and their capabilities. The paper compares current to required state and proposes possible solution of identified problems. 2. Military robots for military engineering, their features, taxonomy and basic requirements Modern armies implement the most modern and advanced military systems. These systems extend capabilities of the individual army branches and of the armies as a whole. Application of advanced unmanned systems will probably continue in haste. Their significance will grow quickly and by now we can predict rising numbers of unmanned systems across all domains – air, land and sea. These systems confirmed in the past military operations that can improve situational awareness, situational understanding, reduce manpower, increase performance of own forces, minimize risks for civilians and reduce overall costs in recent military operations. 2.1 Military robots features and basic requirements and characteristics The need of application of robotics into military engineering is stressed in US Unmanned Integrated Roadmap (UIR) and even in Concept of building ACR [4]. UIR considers combat engineering as area of activities suitable for robotics (unmanned systems) application. Additionally, the document states that unmanned systems can provide persistence, versatility, ability to survive and reduction of risk to human life. In many cases, robotics can be preferred alternative to perform 3D (dirty, dull and dangerous) tasks [5]. According to Concept of building ACR, essential engineer tasks to be conducted by advanced robotic system in the future (year 2025) [4]. So we can see clear demand for an application of (military) engineer robots that will be able to perform engineer 3D tasks including highly specialized task of combat and general engineer support. But why are these systems to be deployed in the future? Figure 1: Well suited tasks for unmanned (robotic) systems according to UIR Source: [5 – modified by author] Firstly, we have to understand fundamental features that defines contemporary robotic systems and basic requirements. Unmanned systems are preferred alternative within tasks called 3D – dirty, dull and dangerous. Specific features of these systems contribute to possible replacement of soldiers by robots in military operations and can be very usefully converted into military. Unmanned systems differ from classic manned (organic) systems in many ways. It makes them very special and very suitable for conducting military engineer tasks. Robots enable soldiers to concentrate on other tasks, they have ability to perform tasks persistently and they are immune to fatigue (constant effort and persistence). Robots have immunity to stress, fear and emotions. They are non-aggressive and safe. What is more, they are resistant to work in extreme conditions but also 28 expendable and replaceable. They are capable of advanced sensing of operational environment due to sensors and can be faster than human (in terms of mobility and decision-making). And finally, robots do not need individual training. The conditions of deployment of robots in land forces permit to determine the general requirements to be met [6]: Be able to progress and/or stay in a complex and hostile environment; Be able to analyze and understand the situation it is being used in and modify its behavior appropriately; Be able to realize an operational effect or conduct technical processes (e.g. the opening of an itinerary, intervention on an IED, survey and alert, etc.); Be able to fulfil its missions permanently; Appropriation of robotic systems by the soldier. Human Machine Interface should be intuitive and simply accessible to the soldier, whatever the conditions of employment and the characteristics of the environment; Be interoperable. Additionally, unmanned systems and other similar technological advancements can hugely affect military practice. The recent technological advancements and innovations have contributed to combat engineering in three main areas [2]: Automation to enable leaner manning of combat engineering equipment; Reduction of time spent on combat engineering tasks; Improvement of man-machine interfaces and ergonomics to make system safer and easier to use. Undoubtedly, these areas also represent one of the basic requirements of advanced engineer robots next to elementary requirement as ability to perform 3D (dirty, dull, and dangerous) or 3H (hot, heavy and hazardous) tasks. Ability to fulfil 3D tasks is the key and the most important requirement for military (engineer) robots. Dangerous tasks – robots must increase survivability of the troops in contact; Dirty tasks – ability to increase the soldiers capacities and finally the operational efficiency of the different units; Dull tasks – ability to permit the realization of repetitive and fastidious tasks. From the text above we can imagine the complexity and comprehensiveness of the problematics of unmanned and robotic systems. Thing are even getting more complicated whet it goes to technical issues, but it is beyond scope of this paper. 2.2 Military robots taxonomy Globally, robots can be divided according to various criteria – control taxonomy, operational medium taxonomy or for example functional taxonomy. Based on their features and intended use, robots can be defined as industrial or service. Service robots are able to perform non-manufacturing, handling and other operations [7]. Military robots are typical service robots that are usually designed to perform task in hostile or hazardous environment. Hazards may be present in the form of radiological or toxicity dangers to potential explosions [8]. In NATO countries, military robots are frequently defined as unmanned systems. These systems are divided into: UAS (Unmanned Aerial System); UGS (Unmanned Ground System; UMS (Unmanned Marine System). For the purpose of this paper, we can be also categorize these systems by their branch application – combat, reconnaissance, artillery, engineer, logistic, medical, chemical and others. 29 It is also necessary to define the term Engineer robot. This term is not commonly
