robotic skill learning has been increasingly studied but the demonstration collections are more challenging compared to collecting images/videos in computer vision and texts in natural language processing. This paper presents a skill learning paradigm by using intuitive teleoperation devices to generate high-quality human demonstrations efficiently for robotic skill learning in a data-driven manner. By using a reliable teleoperation interface, the da Vinci Research Kit (dVRK) master, a system called dVRK-Simulator-for-Demonstration (dS4D) is proposed in this paper. Various manipulation tasks show the system's effectiveness and advantages in efficiency compared to other interfaces. Using the collected data for policy learning has been investigated, which verifies the initial feasibility. We believe the proposed paradigm can facilitate robot learning driven by high-quality demonstrations and efficiency while generating them.

Safety and stability are the key factors for the robot to successfully reach the specified target position, especially in the disturbed environment. In such conditions, the robot is subject to a variety of unknown disturbance, which can lead to system failure. Based on the kinematic model of wheeled mobile robot (WMR), this paper discusses the safety control strategies for trajectory tracking. The proposed strategy combines backstepping control method and control barrier function (CBF), incorporating a disturbance observer to estimate and compensate for disturbances. Then, construct the CBF such that it satisfies the conditions of the safety set and possesses forward invariance. Safety constraint is transformed into the state-dependent linear inequality constraint, and solve the controller using quadratic programming (QP), to ensure collision-free operation of the vehicle in the face of disturbance errors.

A fundamental challenge of autonomous driving is maintaining the vehicle in the center of the lane by adjusting the steering angle. Recent advances leverage deep neural networks to predict steering decisions directly from images captured by the car cameras. Machine learning-based steering angle prediction needs to consider the vehicle's limitation in uploading large amounts of potentially private data for model training. Federated learning can address these constraints by enabling multiple vehicles to collaboratively train a global model without sharing their private data, but it is difficult to achieve good accuracy as the data distribution is often non-i.i.d. across the vehicles. This paper presents a new confidence-based federated distillation method to improve the performance of federated learning for steering angle prediction. Specifically, it proposes the novel use of entropy to determine the predictive confidence of each local model, and then selects the most confident local model as the teacher to guide the learning of the global model. A comprehensive evaluation of vision-based lane centering shows that the proposed approach can outperform FedAvg and FedDF by 11.3% and 9%, respectively.

With the rapid development of AI hardware accelerators, applying deep learning-based algorithms to solve various low-level vision tasks on mobile devices has gradually become possible. However, two main problems still need to be solved: task- specific algorithms make it difficult to integrate them into a single neural network architecture, and large amounts of parameters make it difficult to achieve real-time inference. To tackle these problems, we propose a novel network, SYENet, with only 6K parameters, to handle multiple low-level vision tasks on mobile devices in a real-time manner. The SYENet consists of two asymmetrical branches with simple building blocks. To effectively connect the results by asymmetrical branches, a Quadratic Connection Unit(QCU) is proposed. Furthermore, to improve performance, a new Outlier-Aware Loss is proposed to process the image. The proposed method proves its superior performance with the best PSNR as compared with other networks in real-time applications such as Image signalprocessing(ISP), Low-Light Enhancement(LLE), and Super-Resolution(SR) with 2K60FPS throughput on Qualcomm 8 Gen 1 mobile SoC(System-on-Chip). Particularly, for ISP task, SYENet got the highest score in MAI 2022 Learned Smartphone ISP challenge.

The need for automation in the textile industry is growing rapidly today. Color based object sorting is a highly challenging process to be considered and needs to be addressed. It involves an automated material handling system. It synchronizes the movement of robotic arm to pick up objects moving on a mobile robot. It aims in classifying the colored objects then picking and placing the objects in its respective pre-programmed place. Thereby eliminating the monotonous work done by human, achieving accuracy and speed in the work. The core objective of the project is to propose an intelligent color-based object sorting system using deep learning technique like Convolution Neural Network for extraction of feature embedded with the machine learning algorithm. The two classifiers Random Forest and K-NN algorithm were implemented and studied for better classification. Based on the performance metrics, the Radom Forest algorithm out performs in classification. The project module involves cameras that captures the object's color through the computer vision Library and sends the signal to the controller. The dataset of the captured images has been uploaded and compared with the trained data set. The ESP 32 Module transmit a signal to relay circuit, which then drives the robotic arm's multiple motors to grip the object and position it in the given area. Based on the color observed, the robotic arm goes to the given point, releases the object, and returns to its original position.

Using egocentric video and head motion data from 67 order picking tasks (244 picks;149 orders), we learn visual models of the 10 objects picked to fulfill the orders. Boundary segmentations of the four actions (pick, carry, place, carry empty) of order picking had an average test RMSE of 1.11 seconds using computer vision and 5.53 seconds using only head motion (approximate to 39.8 seconds/task). The 10 objects were clustered with 93.8% accuracy using weak supervision provided by the picks (which could occur in any order) specified in the tasks. We apply the 10 resulting models on independent test data to recognize three objects involving 50 tasks (185 picks;98 orders) and 10 objects involving 10 tasks (35 picks;24 orders). Accuracy was up to 90.3% and 69.1%, respectively. We propose order picking as a practical use case of egocentric Symbiotic AI, where ambient sensing is used without explicit supervision to train an agent which can then help the user improve task speed and accuracy.(1)
