A dynamic model of a walking robot is proposed for moving along surfaces of different topologies and orientations to the horizon. The principal difference between walking robot mechanisms is that they are made in the form of flexible pedipulators. Actually the pedipulators are a set of spherical rings with a hydraulic or pneumatic drive. The patented design (Patent UA No 117065, publ. 2018.06.11) of the robot's feet is anthropomorphic and allows the robot to work in the angular coordinate system inherent in the human walking machine. The proposed mathematical model allows us to calculate the dynamic parameters (forces and moments) and compare these parameters with the allowable technological load that a walking robot can perform without losing adhesion with the displacement surface.

Abstract A mathematical-physical model of a supersonic missile was built, taking into account the mass and inertia properties. The model was implemented in the MathCAD14 simulation program. A numerical analysis of the missile ballistics was conducted and basic parameters were determined: range, altitude, velocity and acceleration, which enabled a test range program for manufactured missile models to be drawn up. Initial flight tests of missiles were carried out at the test range. Satisfactory accordance of experimental and theoretical dynamic parameters of the missile under study was obtained.
