Automatic welding of box girders can greatly increase production efficiency. To locate the welding workspace, it is necessary to reconstruct a map of the box girder and extract features from it. In this paper, we propose a robust LiDAR-inertial odometry (LIO) to build the map and a feature extraction method to locate the webs. For the LIO, we implement map loading and map update function based on FAST-LIO2. The map loading function sets prior values for map building, which will improve its accuracy and matching success rate. And we propose a new data structure, Mark-ikd-Tree, to update the map, which can ensure the freshness of it. For the point cloud feature extraction method, we propose a density-based planar extraction method for the webs in box girders. This method can detect the webs quickly, accurately and without missing. Finally, after obtaining the coordinates of the webs, we estimate the welding workspace by the relative position relationship of the webs and the weld. We validate our method in the experiment section. The positioning error of the webs is around 2 cm.

Based on the piezoelectric drive principle and near-field acoustic levitation(NFAL) technology, a noncontact gyroscope driven by ultrasonic energy is proposed in this paper. The ultrasonic energy generated by a piezoelectric actuator is used in this driving method to provide levitation and rotation-driving force for the gyroscope rotor. The performance parameters of the piezoelectric actuator are predicted based on finite element analysis method. A levitation gyroscope driving test experiment system is built to obtain the levitation mechanics parameters and drive parameters of the levitation gyroscope. The results of levitation and driving experiments show that the gyroscope rotor successfully realizes noncontact rotation at a certain levitation height, which verifies the feasibility of the drive method. The study on acoustic suspended gyroscope and its performance provides an innovative approach to noncontact actuation.

With the rapid development of green energy, inverter technology has become a key technology for renewable energy. To solve the problem of low output voltage of photovoltaic panel, a two-stage topology is proposed. The front stage adopts high-frequency isolated phase-shifted full-bridge structure, which can realize soft-switching technology. The last stage is single-phase inverter structure. In order to achieve high efficiency, high quality output and improve the dynamic and static performance of the inverter system, based on the traditional double closed-loop proportional integral (PI) control, the current control loop proportional control and voltage control loop proportional integral resonance (PIR) control method are improved. The parameters are derived by small signal model, and the system is simulated and verified by experiments. The experimental results show that the system has good dynamic and static performance, and can effectively suppress resonance.

In this work, we investigate on the machining performance of a hole-making 6R serial robot with small rated load and try to optimize the machining quality by adjusting the machining pose. Five different poses of the end-effector are tested, and the stiffness of the robot in each direction is obtained through measuring the displacement of the robot end under a given applied external force. It is found that the greater the stiffness is, the higher quality of the machined hole is, suggesting that the pose of the robot should be carefully chosen for drilling to guarantee that the end-effector is at the highest stiffness state.

Surface topography simulation is crucial in studying the surface texture of workpieces, controlling processing quality, and optimizing process parameters. Nondevelopable ruled surfaces are often used for high-precision surface components due to their unique geometric features, making the simulation method of non-developable ruled surfaces an area of widespread interest among scholars both domestically and abroad. However, due to the geometric characteristics of nondevelopable ruled surfaces and the characteristics of flank milling processing, current simulation efficiency optimization methods are not suitable for simulating the topography of nondevelopable ruled surfaces in flank milling processing. To solve the problem of low simulation efficiency of traditional morphology simulation algorithms based on Z-map method, this paper proposes an efficiency optimization method for simulating the topography of nondevelopable ruled surfaces in flank milling processing based on the cutting contact condition. In the proposed method, the tool pose traversal process constrained by flank milling contact condition was introduced to the traditional simulation method aiming at reducing the number of cycles for updating residual height of the local surface. Finally, the effectiveness of the optimization method proposed in this paper is verified by simulation experiments and processing experiments.

Aiming at the problems of poor synchronicity and low reliability caused by the independent folding principle of traditional solid surface deployable antenna (SSDA), a new structure based on Bennett mechanism was designed and analyzed in this paper. Firstly, the equivalent transformation principle of the SSDA deploying along two orthogonal axes and a single axis were proposed. The rotation axis, angle and anchor point were determined using Axis-angle method. A parallel deployable mechanism was established by connecting each petal with a synchronous wheel whose axis passes through the focal point of SSDA, which significantly improve the deployment synchronization and system reliability. Based on the Bennett mechanism, a kinematics model of a 10m diameter SSDA was established. The analysis results showed that the deployment process is stable and reliable, which verifies the feasibility of the new designed scheme.

the modular self-reconfigurable robot is a relatively cutting-edge robot with high research value. Modular self-reconfigurable robot is a robot system composed of several unit modules connected and capable of autonomous deformation and reconfiguration. Meta-module is the basic unit and the most important component of the modular self-reconfigurable robot. Each module has complete functions such as docking, perception, motion, and control. Compared with traditional robots, our modular robots have the characteristics of free docking, deformable reconfiguration, and can be changed into different configurations to adapt to different tasks in robot applications. In this paper, we propose a spherical self-reconfigurable robot modular joint with electromechanical connector. The robot joint has three degrees of freedom and can be used as a unit module of a self-reconfigurable robot system to form self-reconfigurable robots with different configurations. An electromechanical connector with a single degree of freedom is proposed for vision-guided docking and electromechanical connection.

The Mars quadrotor is a vertical take-off and landing aerial platform developed to enhance the efficiency of Mars exploration. The four-blade rotor has a high thrust coefficient due to its high solidity, which enables the quadrotor to navigate the Martian atmospheric environment efficiently. This paper proposes a payload-carrying Mars quadrotor featuring four four-bladed rotors that can fold along the rotor arms. The computational fluid dynamics (CFD) method is employed to perform numerical hovering simulations, exploring the propulsion capability and aerodynamic efficiency of rotors with different diameters. The mass distribution and hovering time are estimated when the quadrotor consists of the rotors with the highest figure of merit. The results demonstrate that a larger rotor diameter of the quadrotor yields greater payload capacity and shorter hovering time. During the launch, the quadrotor is folded and constrained within an envelope to protect it from vibrations and shocks. A lifting mechanism with shape-constraint slides is utilized for quadrotor deployment.
