  • Development of the USV path planner based on the unstable mode

    In the article, the method of designing the path planning on the basis of an unstable mode is described. This method is based on the bionic approach and does not require mapping, it reduces requirements for the sensor subsystem. In this article, we propose a method of obstacle avoidance in which an unstable mode is realized in a separate dynamic link. The output of the dynamic link corrects the desired course of unmanned surface vehicle (USV). This allows to set the unstable trajectory of motion only at the planning level, and at the regulatory level to function in a stable mode. In addition, this approach allows you to plan the direction of detour travel. Detailed description of the proposed path planner, as well as the results of the research in Matlab are provided in the article.

  • Path planning for autonomous mini-ship

    The paper deals with the trajectory planning of the mini-ship in an environment with obstacles. The structure of the control system hardware, software architecture built on basis of ROS software environment are presented. Global planner is designed using Voronoi diagrams method. Local planner (regulator) proposed to be implemented using the unstable regimes of control to bypass obstacles near the mini-ship. The results of simulation showed the efficiency of the proposed approaches.

  • Algorithms multiconnection position-trajectory control of mobile objects

    The paper considers the algorithms of position-trajectory control of mobile objects, are automatically distributed control forces and moments on the actuator. The basic control law is based on the equations of kinematics and dynamics and method of position-trajectory control of mobile objects. We consider the distribution of control forces and moments on the basis of pseudo-inverse matrix, which provides minimum MSE. This approach does not provide for preliminary separation of control channels, as is customary in classical systems of mobile objects. The proposed method is applied to the control system of aeronautical complex. The cases of excessive and insufficient number of control channels. The results of the simulation.

  • Development of Autonomous Underwater Vehicle Simulator

    Testing and debugging of real equipment is a time consuming task. In particular, in the case of marine robots, it is necessary each time to carry out the transportation and deployment of a robot on the water. Experiments with not yet fully functional prototype of marine robot equipped with expensive hardware is in the meantime very risky. Therefore, the use of simulators is affordable way to accelerate the development of robotic systems from the viewpoint of labor effort and cost of experiments. This paper presents a simulator specifically designed for autonomous unmanned underwater vehicles.

  • Software complex of detection and diagnosis of hardware failures in robotic marine mobile vehicles

    The paper considers the use of ground station operator’s software that provides the diagnosis of automatic control system of marine vehicles, based on the monitoring of the functional state of the system elements with depth to the type of failure. Also considers the use of neural networks for solving the problems of monitoring, control and state diagnostics of the actuators and sensors.
