The main advantages of the walking platform over their direct competitors — wheeled and tracked platforms are considered. The systematization of various kinematic systems according to their distinctive parameters is carried out, the advantages and disadvantages of the developed system are considered. An innovative kinematic system, which is based on the simplification of the kinematic scheme of a mammal’s leg, which is common in walking robots, is presented. Based on this system, a variant of a mobile walking platform, protected by patent No. 264202, in which two degrees of freedom of the movable leg and the degrees of freedom of the entire device are used to position the leg in three-dimensional space, is proposed. A comparative analysis of the parameters of this design with examples of developments of companies leading in this industry has been carried out.
