The work describes a hybrid algorithm for the dynamic formation of a robot’s movement route in nondeterministic environments with bypassing stationary and nonstationary obstacles for two-dimensional space, based on the integration of wave and ant algorithms, which makes it possible to build trajectories of minimum length in real time with simultaneous optimization of a number of criteria for the quality of the constructed path. Restrictions preventing the construction of a trajectory from the current position are iden-tified during the construction process. The trajectory is constructed step by step. The entire trajectory con-necting the robot’s initial position with the target position is a collection of individual sections. The time complexity of the algorithm depends on the lifespan of the colony, l, (number of iterations); the number of graph vertices, n; the number of ants, m; and is estimated as O(l · n2 · m).
