It was investigated the protective effect by polylayer armors with intermediate layer out of polymeric composition. It was got mathematical model to the action by the individually ingredients by the compositions over the protective effect. They were presented experimental evidence, how investigated compositions are long-term materials to elaboration by polylayer armors to needs by militaryMechanical and mathematic modeling of a robot performing one of regional movements have been done. The hand has been modeled as an elastic bar with distributed mass and the gripper as a plane disk. The robot performs a movement with limited power of driving under technology conditions. Differential equations describing the micro and macro movements of the system have been drawn.
