The equations of kinematics and dynamics are written out; and the issue of optimizing the robot’s movement is considered. The robot’s gait is analyzed, in which part of the legs is on the ground and supports the robot, and part of the legs moves in the air. At the first stage for solving this problem, one leg is considered separately, as a kinematic system with open kinematics and with three degrees of freedom. The kinematics equations were presented in matrix form using the principle of rotation of the coordinate system. The dynamics equations are based on Lagrange equations of the second kind. The mass of the legs, reduced to the center of gravity, moments of inertia, moments developed by engines were taken into account, and etc. The conclusions were made about the optimal movement of the leg based on the obtained equation of kinetic energy of the robot’s leg based on the obtained equation of the kinetic energy of the robot leg.
