Enhancing the generalization capacity for semantic segmentation of aerial perception systems for safety-critical applications is vital, especially for environments with low-light and adverse conditions. Multi-spectral fusion techniques aim to maintain the merits of electro-optical (EO) and infrared (IR) images, e.g., retaining low-level features and capturing detailed textures from both modalities. However, these techniques encounter limitations when faced with scenarios involving missing modalities, especially during inference when only IR images are available. In this paper, we propose a novel spectralbased knowledge distillation architecture known as SKD-Net to improve the performance of deep learning models for missing modality scenarios for semantic segmentation tasks. In this architecture, we make use of Gated Spectral Unit to combine information from both modalities. SKD-Net aims to extract valuable semantic information from EO images while preserving spectral knowledge from the IR images within the feature space. The model retains the style information in the shallow layers while simultaneously fusing the high-level semantic context obtained from EO and IR images to improve the feature generation capacity when dealing with only IR images during inference. SKD-Net outperforms state-of-the-art multi-modal fusion and distillation models by 2.8% on average in scenarios with missing modalities when using only IR data during inference in two public benchmarking datasets. This performance increase is achieved without additional computational costs compared to the baseline segmentation models.

Asynchronous microphone array calibration is a prerequisite for many audition robot applications. A popular solution to the above calibration problem is the batch form of Simultaneous Localisation and Mapping (SLAM), using the time difference of arrival measurements between two microphones (TDOA-M), and the robot (which serves as a moving sound source during calibration) odometry information. In this paper, we introduce a new form of measurement for microphone array calibration, i.e. the time difference of arrival between adjacent sound events (TDOA-S) with respect to the microphone channels. We propose to use TDOA-S and TDOA-M, called hybrid TDOA, together with odometry measurements for bath SLAM-based calibration of asynchronous microphone arrays. Extensive simulation and real-world experiments show that our method is more independent of microphone number, less sensitive to initial values (when using off-the-shelf algorithms such as Gauss-Newton iterations), and has better calibration accuracy and robustness under various TDOA noises. Simulation results also demonstrate that our method has a lower Cramer-Rao lower bound (CRLB) for microphone parameters. To benefit the community, we open-source our code and data at https://***/AISLAB-sustech/Hybrid-TDOA-Calib.

A novel adaptive fuzzy optimal compensation control approach is developed for modular robot manipulator (MRM). By incorporating integral reinforcement learning (IRL) to value iteration (VI), the adaptive fuzzy optimal control approach effectively addresses the trajectory tracking problem without accurate dynamic model information, and break the limitation of traditional policy iteration (PI). Moreover, this article approximate cost function with fuzzy logic system (FLS), which simplify the solution of the optimal control policy and better capture the important features of the cost function.

Developing deep underground energy resources is crucial for addressing our country's energy imbalance. To tackle unsafe conditions and high communication latency, we designed a Remote control Human-Machine Interaction System for Robotic Arms. Using dual MYO armbands to collect human arm joint data, Quaternion data is converted into Euler Angles for the robotic arm joints. This study focuses on Motion Mapping in the Joint Space from the master arm to the slave arm. Integrating Model Predictive controltechnology predicts the motion of the slave arm joints, achieving effective Remote control and significantly reducing latency.
