Adversarial Geometric Traps: A DRL-Driven ROS 2 Framework for Robust Mapless Navigation in Dead-End Scenarios

Reactive local planners such as the Dynamic Window Approach (DWA) often fail in non-convex dead-end structures because their greedy objective drives the robot into local minima. This paper presents a ROS 2-native mapless navigation framework that trains a Proximal Policy Optimization (PPO) agent using a Procedural Adve...

Early Recognition and Temporal Stability in Three-Channel Low-Density EMG: Impact of Segmentation Strategies for Real-Time Myoelectric Interfaces

Wearable electromyography (EMG) interfaces enable natural human-robot interaction, and low-density configurations are preferred for practical deployment due to their simplicity and cost-effectiveness. However, limited spatial information challenges reliable and timely pattern recognition. This study compares three segm...
