This paper proposes a parameterization method to represent SO(3) over multiple turns. This method is called a memory-based parameterization, because the idea is to integrate the past trajectory of exponential coordinates. The parameterization is consistent in the sense that the true rotation matrix can be reconstructed by using the exponential map. As an application of the proposed method, a 6D impedance controller is designed with a radially unbounded potential function. Consequently, in contrast to the conventional methods, an arbitrarily large angular deflection can be accommodated, resulting in a more realistic impedance behavior. The proposed schemes are validated through simulations and experiments.

In the evolution of software engineering, significant focus has been directed toward automating various stages of software product development, encompassing everything from documentation creation to the generation of startup and installation scripts. The automation of user interface element generation has consistently been a key area of research. Despite the existence of numerous solutions aimed at supporting the automation of various processes and components, the lack of widely adopted methods and tools for user interface generation indicates that this challenge remains unresolved. This paper proposes a solution for web application user interface prototype generation based on the Two-hemisphere model, which represents problem domain scenarios for the application to be generated and the preliminary data structures.

The task of detecting breakdowns helps to improve the reliability of industrial devices through early identification of problems and their timely resolution, which helps to improve the resource and energy efficiency of production as a whole. When modeling breakdowns of industrial electric motors, the following characteristics are primarily taken into account: average load, rotational frequency, power supply voltage, current consumption, leakage current, collected from data from a traditional automated control system and breakdown logs of repair teams of an industrial enterprise. The model for detecting reliability and breakdowns of electric motors in the work is built on an anomaly detection algorithm using unsupervised machine learning methods. Its effectiveness has been successfully tested using many evaluation metrics. It can be used for a range of tasks and applications in equipment management and maintenance, visualization, forecasting and management decision support.

Accurate and robust initialization is crucial in visual-inertial system, which significantly affects the localization accuracy. Most of the existing feature-based initialization methods rely on point features to estimate initial parameters. However, the performance of these methods often decreases in real scene, as point features are unstable and may be discontinuously observed especially in low textured environments. By contrast, line features, providing richer geometrical information than points, are also very common in man-made buildings. Thereby, in this paper, we propose a novel visual-inertial initialization method integrating both point and line features. Specifically, a closed-form method of line features is presented for initialization, which is combined with point-based method to build an integrated linear system. Parameters including initial velocity, gravity, point depth and line's endpoints depth can be jointly solved out. Furthermore, to refine these parameters, a global optimization method is proposed, which consists of two novel nonlinear least squares problems for respective points and lines. Both gravity magnitude and gyroscope bias are considered in refinement. Extensive experimental results on both simulated and public datasets show that integrating point and line features in initialization stage can achieve higher accuracy and better robustness compared with pure point-based methods.

This paper proposes a method to compute camera 6 DoF poses to achieve a user defined coverage. The camera placement problem is modeled as a combinatorial optimization where given the maximum number of cameras, a camera set is selected from a larger pool of possible camera poses. We propose to minimize the squared error between the desired and the achieved coverage, and formulate the non-linear cost function as a mixed integer linear programming problem. A camera lens model is utilized to project the camera's view on a 3D voxel map to compute a coverage score which makes the optimization problem in real environments tractable. Experimental results in two real retail store environments demonstrate the better performance of the proposed formulation in terms of coverage and overlap for triangulation compared to existing methods.

The integration of Large Language models (LLMs) with robotic systems has opened new avenues for the development of empathetic and interactive robot partners. This paper introduces a service robot system that incorporates multi-modal emotion recognition and LLM-based emotion dialogue generation. The system captures user emotions through a tri-modal emotion recognition model (TriMER), which processes audio, text, and facial expressions using advanced techniques like BiLSTM, CNN, and Deformable Convolutional Networks (DCN). Experiments conducted using the IEMOCAP dataset show that our TriMER model achieves an accuracy of 74.15% in recognizing emotions. By combining emotion recognition with LLM, the robot can better understand and respond to human emotions, facilitating more natural and empathetic interactions. This development holds promise for applications in elder care, aiming to enhance both physical and mental well-being.

This paper introduces an efficient direct visual odometry (VO) algorithm using points and lines. Pixels on lines are generally adopted in direct methods. However, the original photometric error is only defined for points. It seems difficult to extend it to lines. In previous works, the collinear constraints for points on lines are either ignored [1] or introduce heavy computational load into the resulting optimization system [2]. This paper extends the photometric error for lines. We prove that the 3D points of the points on a 2D line are determined by the inverse depths of the endpoints of the 2D line, and derive a closed-form solution for this problem. This property can significantly reduce the number of variables to speed up the optimization, and can make the collinear constraint exactly satisfied. Furthermore, we introduce a twostep method to further accelerate the optimization, and prove the convergence of this method. The experimental results show that our algorithm outperforms the state-of-the-art direct VO algorithms.
