In order to reduce sideslip and tail flick for Polar Region Hovercraft on snow and ice layer, a multiple control surface coordinated distributed allocation strategy with air propeller, air rudder and bow nozzle is proposed. First of all, a mathematical model for the maneuverability of the hovercraft traveling on ice surfaces is established, and the tail swing characteristics of hovercrafts traveling on ice and snow surfaces are obtained. Then multi-surface coordinated control allocation is realized with air propeller for speed control, air rudder for heading control, and bow nozzle for sidelip control. Finally, simulations for hovercraft turning on ice surfaces are carried out to valid the effectiveness of the control allocation strategy.

With the increasing demand for the exploration of marine resources and the observation of marine issues, many aquatic-aerial vehicles were developed. This paper developed a small agile water aquatic-aerial vehicle that can fly in the air and swim in water. A foldable mechanism was proposed to reduce excessive underwater resistance caused by its specified flight structure, and a bi-stable structure was proposed to maintain the stability of the foldable mechanism and reduce the consumption of the servo. The mechanical modeling of the foldable mechanism is established. And the servo with the torque of 45kg$cdot$cm is able to open the foldable mechanism 0.4s to complete the mode conversion of cross medium when the aircraft jumps out of the water. CFD simulation was also carried out in water. Driven by thruster with 38N propulsion, the vehicle reaches a speed of 5.1m/s. Finally, the vehicle prototype was assembled. In the future, we will focus on underwater motion and aerial flight experiments, and ultimately achieve cross medium flight.

With the improvement of living standards, the development of human industry has brought a lot of problems to the environment, especially soil and water pollution. Therefore, rapid detection of harmful substances is of great significance. At present, flow injection method is commonly used in the world, which can be used for rapid and accurate detection of water quality. One of the more important links is the separation of gas and liquid. Based on the existing gas-liquid separation devices on the market, this paper optimizes the design of a high-efficiency gas-liquid separation device for flow injection, which can quickly peel the gas from the liquid in the detection process. Through the analysis of the gas-liquid flow path, the separation mode and mechanism are studied, and the simulation of the gas-liquid separator and the real experiment test have achieved the ideal effect, thus verifying the feasibility of its optimal design. This paper describes the gas-liquid separation device including mechanical design, flow path analysis, simulation and experimental verification.

An improved multi-robot cooperative strategy based on the improved artificial bee colony algorithm is proposed for the task of underwater multi-robot cooperative area target search. The strategy consists of three stages: cruising stage, building capture alliance stage, and cooperative search stage. In the cruising stage, robot adopts the improved random walk algorithm for aimless cruising. In the building capture alliance stage, robot uses an auction algorithm for the assignment of search tasks. In the cooperative search stage, robot adopts the improved artificial bee colony algorithm for cooperative search of targets. Furthermore, simulations are conducted, and the results demonstrate that the proposed strategy can effectively guide multiple robots to perform area target search in unknown 3D underwater environments.

This paper proposes a Hierarchical Path Planner (HPP) based on Even-order Hyperelliptic Orbital Limit-Cycles (EHOLC). Traditional Elliptic Orbital Limit-Cycles (EOLC) have been widely studied. However, in structured rectangular obstacle environments, ellipses have a higher porosity when enveloping rectangles, resulting in lower environmental adaptability. Therefore, EHOLC is introduced, and the hyperelliptic equation order of obstacles is determined based on a set porosity. Then, the differential equation of the EHOLC is established, and the trajectory is solved. Finally, a hierarchical path planner is proposed, which selects obstacle avoidance controllers and target reaching controllers according to the environment map to solve the entire path. Simulation experiments show that compared with traditional EOLC, the EHOLC-based HPP has higher map space utilization, shorter path planning length, and maintains flexibility, smoothness, and safety.

Model predictive control (MPC) can solve the constraint problems of the unmanned system control. However, the model of autonomous underwater vehicle (AUV) is nonlinear, and the Jacobian matrix changes with the state of the AUV, so the traditional linear MPC method is no longer applicable. This paper presents an MPC motion control method based on Lie group theory. We represented the attitude, velocity and position errors of an AUV as an element in the Lie group, and linearized the MPC model by combining the dynamic model of the AUV, so that the Jacobian matrix is only related to the expected value, and the control performance is improved. Simulation results show that, compared with the traditional MPC algorithm, the algorithm in this paper shows stronger robustness when the AUV suffers from large disturbance and state expectation mutation.

Focusing on the polishing operation of automobile hubs, this paper proposed a polishing robot by combining a 1T2R parallel mechanism (PM) and an X-Y worktable. The dimensional synthesis and static/dynamic performance analysis of the 1T2R PM are also presented with the key points as follows. Firstly, the inverse displacement model and velocity model of the PM are built to formulate the motion/force transmissibility indices on the basis of the generalized Jacobian matrix. Secondly, the dimensional synthesis problem is formulated to determine the optimized normalized dimensional parameters by maximizing the global force/motion transmissibility of the PM subject to geometric constraints without mechanical interference. Finally, the finite element (FE) model of the 1T2R PM is built with the aid of the SAMCEF, and the static stiffness and lower-order natural frequencies of the PM are evaluated. The research results of this paper provide dimensions and mechanical structures for developing the physical prototype of the automobile hub polishing robot.

With the widespread use of variable frequency motors in the robotics industry, the issue of their vibration and noise has gradually attracted the attention of scientists. Electromagnetic waves are one of the main excitation sources that cause electromagnetic vibration in variable frequency speed control motors, which directly affects the amplitude and frequency distribution of the vibration. In general research, it is only analyzed as a general excitation source. This paper focuses on the radial electromagnetic waves of small and medium-sized motors, and analyses the radial electromagnetic force using analytical and finite element methods. When compared with the vibration response, the frequency spectrum of the electromagnetic waves is consistent with that of the vibration response. This indicates that in small- and medium-sized motor structures with high rigidity, the main source of vibration in the entire machine is electromagnetic vibration. Therefore, by analyzing the electromagnetic excitation, the motor vibration can be better predicted.
