One of the problem while dealing walking mechanism of mobile service robot (MSR) is the problem of his mechanical organization and control. An example for the solution are locomotive organs of the animals. Biomechanics defines motion as a change of the system position in the space as well as the change of the position of its functional parts. Subsequently space and time -space features of the motion represent kinematical features. Power and time feature represents dynamic features of the moving material system. These signs and features can be used as effective tools for biomechanical analysis of the movement activities and characteristics of random walking body of MSR. Biomechanical model can be used especially by optimization of the construction and driving unit of the walking mechanism, while designing of its control and coordination of the movement of its functional sections. The article introduces authors' knowledge and experience from the use of biomechanical characteristics by the analysis and evaluation of walking service robots movement realization technique, as well as by the creation of the models simulating walk for the needs of the walking mechanism MSR construction.

Driving unit in robots serves, through the change of input energy, programmed precise movement of mechanical movement system. At the same time, the requirements on its optimization lead to the concept of its design with transformer block (transmission), ar without this block. One of the solutions without the transformer block is the usage of the principle of bio-drives (artificial muscle). The paper gives the driving unit set on the principle of modified artificial muscle (tire). The driving unit is constructively simple, with the possibility of minimizing it into real space of the movement unit. The results confirm (linear module) that its efficiency parameters and working qualities are suitable for the construction of robots, mainly for the effectors, or the movement units with small lifts.

The paper presents the knowledge obtained in solving the problem of analysis of working environment and its influence on Robotic System (RS). The working conditions could be described as a sum of a causal parameters by means of so called characteristic of working environment, of application, of actual technical state of RS. Model of working conditions, hyphotetic unit of technical life and program product, by interaction the RS application according to the grade of risky environment and informs about the weak features of solution.
