Today, more than forty countries of the world are engaged in the development of military-purpose robots. A number of unique mobile robots with a wide range of capabilities are already being used by combat and intelligence units of the Armed forces of the developed world countries to conduct battlefield intelligence and support tactical groups. At present, the issue of using the latest information technology in the field of military robotics is thoroughly investigated, and the creation of highly effective information management systems in the land-mobile robotic complexes has acquired a new phase associated with the use of distributed information and sensory systems and consists in the transition from application of separate sensors and devices to the construction of modular information subsystems, which provide the availability of various data sources and complex methods of information processing. The purpose of the article is to investigate the ways to increase the autonomy of the land-mobile robotic complexes using in a non-deterministic conditions of modern combat. Relevance of researches is connected with the necessity of creation of highly effective information and control systems in the perspective robotic means for the needs of Land Forces of Ukraine. The development of the Armed Forces of Ukraine management system based on the criteria adopted by the EU and NATO member states is one of the main directions of increasing the effectiveness of the use of forces (forces), which involves achieving the principles and standards necessary for Ukraine to become a member of the EU and NATO. The inherent features of achieving these criteria will be the transition to a reduction of tasks of the combined-arms units and the large-scale use of high-precision weapons and land remote-controlled robotic devices. According to the views of the leading specialists in the field of robotics, the automation of information subsystems and components of the land-mobile robotic complexes can increase safety, reliability, error-tolerance and the effectiveness of the use of robotic means by standardizing the necessary actions with minimal human intervention, that is, a significant increase in the autonomy of the land-mobile robotic complexes for the needs of Land Forces of Ukraine.

The current level of development of robotic systems of armaments, military and special equipment is characterized by an accelerated transition to their construction on a modular basis. Due to this relatively small nomenclature of initial blocks-modules of lower levels can provide a large variety of the type of land-mobile robotic complexes of specialized functionality. There is an opportunity to quickly adapt the necessary robotic military equipment to specific combat conditions, which guarantees the reliable performance of the assigned combat missions. It is proposed to equip the transport platforms for robotic systems of armament, military and special technics by electromechanical engines on the basis of autonomous drive modules with driven forced electric motors on the basis of rare-earth neodymium permanent magnets. At the same time, record high performance transshipment capacity is achieved, which dramatically increases the ability to overcome difficult road impediments. The article deals with the design features of modular transport platforms for modern robotized weapons, military and special equipment systems, which are conditioned by the need for reliable delivery of weapons, ammunition, equipment, foodstuffs and medical supplies to the personnel on the line of contact with the enemy in difficult geoclimatic conditions. It is shown that the necessary quality of realization of the assigned of combat tasks is ensured by the application of the installation on the platforms of autonomous electromechanical drives of driving wheels.

The choice of energy sources to ensure the smooth functioning of the entire set of actuators of an autonomous transport platform of ground military robot, including traction propulsion, has a decisive impact on the overall performance and viability of the entire GRC (ground robotic complex) and determines, ultimately, its quality and reliability in the process. For covert warfare, recommending the use of energy sources such as internal combustion engines is impractical because of the high levels of inherent acoustic noise. With the advent of electrochemical energy sources, significant progress has been made in the development of a number of high technologies, namely, in the newest fields of technology - portable electronics and power electromechanics. Power sources such as lithium-ion batteries have proven to be much lighter and more compact than other types of batteries. Therefore, electrochemical lithium-ion batteries have been widely used in military robotics, ranging from small UAVs and multicopters to portable ground combat robots and marine robotic vehicles. Recent achievements in enhancing the specific performance of batteries of this type make it possible to use them in the electromechanical motors of modular transport platforms of modern ground robots for covert combat operations with a carrying capacity of up to 500 kg and above. The analytical purpose of the materials in this article is to compare the potential sources of electricity in terms of their practical use in military robotics, namely, in the transport platforms of modern GRC for covert warfare. Frame-modular platforms with a capacity of 50, 150 and 500 kg were adopted for the real objects with installed sources of electricity. The principal feature of these platforms is the presence of rigid tubular modular horizontal frame made of precision steel or composite tubes. In the internal cavities of these pipes it is proposed to install power sources made in the form of cylindrical functional blocks-modules.
