The paper describe project of shoulder from the suspension system of rescue autonomous platform. The shoulder is designed as part of the suspension system working in modular system allows easy assembly and removal of the suspension with the wheels. The project as described in the article is a continuation of a scientific thesis titled Project of elements of the mode of halt of the self-propelled platform guided remotely written by one of the authors under the supervision of professor Stanisław Radkowski. Suspension Shoulder is designed in 3D. The article describes the modeled material and determined the weight of the shoulder. Making a simulations of strength under load in computer program SolidWorks and Ansys. In addition, the article presents a proposal for Authors for a modular solution to the problem of rapid assembly and disassembly of the suspension. Taking into account the installation of electrical motors located in the wheel rims autonomous platform. Suspension is a corps designed like the crank of the bicycle, which has the force of gravity to move the whole platform from the load
