This paper introduces a teleoperated mobile robotic manipulator specifically designed for rescue operations. The system integrates a robotic manipulator, a mobile platform, a hybrid power system, an environmental perception system, and a teleoperation console, forming a modular and highly adaptable architecture. A key innovation is the Feedback Correction Loop, which improves manipulator control by mitigating issues like communication delays, workspace constraints, and packet loss. Experimental results validate the effectiveness of the framework, demonstrating that the system can execute tasks smoothly, continuously, and safely under teleoperation.

Given the numerous drawbacks of manual grinding for castings, the use of robots for intelligent grinding is quickly becoming an unavoidable trend. This paper introduces the design of a grinding robot system for the intelligent grinding of medium and large non-standard castings. The proposed system uses labels to identify and scan the surface that needs grinding, subsequently registering and segmenting the obtained point cloud. From here, it converts the select grinding area into a triangular mesh surface, and maps it onto a parametric domain using the re-parameterization method. The system then plots a path on the plane and maps it back onto the original workpiece, acquiring the final grinding path after necessary tool axis adjustments. The grinding head is then manipulated to perform constant force grinding, employing the PID control. Tests have shown that the system can effectively grind the surface of medium and large nonstandard castings in real-world industrial settings.

Pedestrian positioning technology is a key technology that has emerged in recent years in the field of navigation. It is of great significance in indoor, underground and other navigation fields. In this paper, aiming at the problem of error accumulation in pedestrian positioning systems based on MEMS devices, a pedestrian positioning method based on the inertial navigation scheme is studied, and the zero-velocity correction method is used to suppress the accumulation of velocity errors, thereby improving the positioning accuracy. The effectiveness of the method in this paper is verified by experiments.

In the field of autonomous driving, drifting control is of great importance for driving safety to deal with extreme situations. In order to better control the unmanned vehicle, it is necessary to have high-precision and high-frequency state information. To obtain state information, onboard sensors has the advantages of a lower cost, convenient deployment, indoor and outdoor versatility, etc. In this paper, we propose an onboard sensor estimation scheme using 2D LiDAR and IMU to support the control of a stable circular drifting task. We implement our method on a 1/10 scale radio control car. It can realize stable drift with a given center and radius, which illustrates the effectiveness of our method. A video of the cars performance can be found at https://***/video/BV1Fg411z7XH/.

Shooting Intelligent Detection System has important applications in the military industry. Existing target shooting systems mainly face problems such as high cost, complex operation, and poor environmental adaptability. Considering the above limitations, in this paper we propose a fast, low-cost, and easy-to-deploy bullet hole recognition algorithm based on visual detection, which mainly consists of four parts: image preprocessing, extraction of target center, bullet hole extraction and ring value determination. In the process of bullet hole extraction, a method for segmenting effective target surface is proposed to cope with the problem of off-target bullet holes. Our method can not only accurately localize the bullet holes, but also obtain the exact ring value at that location. In addition, due to the robust adaptability of our method, it can even be applied to outdoor scenarios.

The flapping wing robot (FWR), inspired by avian aerodynamics, is a distinct category of unmanned aerial vehicles (UAVs). Different to general UAVs, such as quadcopters, FWRs are featured by their superior aerodynamic capabilities, minimal noise generation, inherent stealth, and lower energy consumption. As a result, they are rapidly becoming vital tools in a variety of civilian and military activities including environmental monitoring, disaster detection, search and rescue operations, ecological conservation, and military manoeuvres. Our study introduces the comprehensive integration of a light detection and ranging (LiDAR) module, serving as a visual perception device, with a large FWR that is equipped with 2-meter, two-segment wings. Based on this setup, the geospatial information of targeted area is captured and compared to the existed topographic data.
