2025 Leveraging Lightweight Neural Networks and Catastrophic Forgetting Mitigation for a Two-Wheeled Self-Balancing Robot
abstract
As artificial intelligence (AI) technology advances, its applications expand into various fields, including robotic motion control. Self-balancing robots commonly employ PID or LQR control and typically require extensive parameter tuning for proper execution. An emerging alternative is using deep reinforcement learning algorithms, leveraging on Lightweight Neural Networks (NNs) and Catastrophic Forgetting Mitigation, in robot control. This paper details the process and outcomes of training a Q-network within a virtual environment via a deep Q-network (DQN) algorithm, preventing the network from getting overtrained and deploying it on a microcontroller to achieve a self-balancing robot. Additionally, it describes methods for facilitating interactions between the self-balancing robot and the real-world environment during training.

2025 Dynamic Quantization and Pruning for Efficient CNN-Based Road Sign Recognition on FPGA
abstract
In this paper, we present an optimized implementation of Convolutional Neural Network (CNN) for road sign recognition on an FPGA platform, utilizing dynamic quantization and pruning techniques. Traditional CNN models are computationally intensive and require significant memory, which poses challenges for deployment on resource-limited hardware such as FPGA. To address these challenges, a hybrid approach was proposed combining dynamic quantization with pruning, allowing layer-specific precision adjustment while removing unnecessary network connections. This method significantly reduces the computational complexity and memory usage while maintaining high accuracy in road sign recognition tasks. The quantized and pruned model is implemented on the Tang Primer 25K FPGA, demonstrating efficient hardware utilization and real-time performance. Experimental results show that the proposed approach substantially reduces power consumption and resource utilization, with minimal impact on accuracy, making it highly suitable for embedded systems and edge computing applications.

2024 Enhancing Accuracy and Stability in Standing Wave Acoustic Levitation Systems
abstract
Acoustic levitation, an emerging technology that employs sound waves to suspend solid particles and liquid droplets in mid-air, holds immense promise. Its potential applications span diverse fields, including environmental science, mechanical engineering, biochemistry, food science, and cancer therapy. The method involves manipulating matter using sound waves to create novel forms of energy and material. However, standing wave acoustic levitation faces challenges, particularly unstable soundwaves that hinder stationary levitation. This study delves into the intricacies of the standing wave acoustic levitation system. Additionally, it compares this method with near-field and parametric array levitation techniques. Each approach utilizes sound waves to create “invisible fingers” that hold objects, but they have distinct advantages and limitations. To address instability, two standing wave acoustic levitation systems are constructed and tested: a simpler version and an expert-level setup. The goal is to enhance accuracy and stability. Ultimately, this research aims to unlock the full potential of acoustic levitation.

2016 Asymmetrical Dead-Time Control Driver for Buck Regulator
abstract
This brief presents an asymmetrical dead-time control driver (ASDTCD) for synchronous buck converter operating in the continuous conduction mode. Dead-time control is an important metric for improving the efficiency of switching mode power regulator. Without an additional circuit, the proposed ASDTCD can generate dead time by controlling the slope for the output signal of the driver. The proposed ASDTCD utilizes the transition between triode region and saturation region for the power transistor to avoid body-diode conduction and shoot-through current while minimizing the switching loss. Thus, high-speed body-diode conduction sensor is avoided; thereby, reducing the power consumption and saving silicon area. In addition, the body-diode conduction time control accuracy is also enhanced. Less than 1-ns body-diode conduction time has been achieved without bringing in shoot-through current across 10-450-mA load range. With less than 0.5% of the total input power consumed, the proposed ASDTCD takes less than 1% of the power transistor area. This design is implemented in the 0.18-μm CMOS process.
