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.

The analysis of the correspondence of the set of functional indicators of industrial robots to the criteria of criteria similarity conditions is carried out. Using the methods of the theory of dimensions, criteria for the similarity of the functional properties of carrying capacity, speed-action and dynamism of industrial robots in terms of rotational and translational degrees of mobility have been determined. The necessary set of criteria has been created and a concept has been proposed for determining the generalized criterion complexes of the load capacity for modules, aggregates and the entire structure of the robot as a whole using the method of defragmentation and averaging the corresponding criteria by degrees of mobility. The proposed performance criterion makes it possible to compare the performance of a group of robots in terms of three kinematic indicators: speed, acceleration and the range of permissible displacements. For robots of light load capacity, the technical evolution of the considered criterion complexes is presented. It is noticed that with an increase in the reach of the robot, the criterion of load-carrying capacity for all robots decreases. The developed criteria make it possible to assess the speed action and loading capacity of a robot of any design and can be used to determine the technical level of robots and identify reserves for increasing it. Key words: degrees of mobility; manipulation system; homogeneous functions; dynamic parameters

The article considers the problems related to the need to develop for the Armed Forces of Ukraine specialized robotic transport equipment for the military logistics system, namely – electromechanical tractors with high specific performance, capable of providing not only fast and covert delivery of weapons, military and special equipment, ammunition and personnel to the places of combat operations, but also the evacuation of the wounded and damaged equipment from the battlefield. Methods of realization of the set tasks on the basis of use of topological transformations and local scaling prototype are offered robotic tractor without a cabin Case IH Concept with a power plant a diesel engine with a power of 308 kW, a maximum speed of up to 50 km/ h and four double support-driving wheels of two different diameters. Topological transformations have shown the possibility of equipping a robotic, reduced in scale 1: 2 compared to the real prototype, a large-scale copy of an electromechanical tractor with high specific performance based on composite platforms of triangular generating autonomous blocks-modules. Modular structuring of the basic element of the platform of a specialized electromechanical tractor of military logistics from traction functional blocks-modules in the form of triangular autonomous units of multimodal transport provides their implementation as real three-wheeled electric motorcycles, which are fully suitable for autonomous practical application.
