Special Issue Information

Dear Colleagues,

Humanoid robots and prosthetic hands aim to mimic a variety of human-like behaviors, such as moving, grasping, lifting, and more. In recent decades, researchers have attempted to build humanoid robots and prosthetic hands capable of replacing human hands. However, despite prosthetics being a means of improving disability, activity difficulties, and health-related quality of life, many arm amputees rely on outdated devices.

Researchers need more diverse methods based on the collection and processing of biological signals to recreate all the different functions of the human hand, as it remains a challenge because of its complexity. Advances in neural signal acquisition, computer decoding and encoding methods of neural/biological signals, robotics for robotic hands, and computer vision using deep learning are relevant. These areas have the potential to provide standards to support robotic/prosthetic hand strategies.

There are several requirements in this area. One of the basic requirements is that the design should be as close as possible to replacing the natural hand. Another requirement is that, if used in prosthetics, the alternative control method should be flexible, such as muscles that can collect and process biological signals. A further requirement are innovative applications with new technologies, such as deep learning, IoT, and 5G.

We invite investigators to contribute original research articles and review articles addressing robotic/prosthetic hands that facilitate advances in rehabilitation/humanoids, such as brain–machine interfaces, neuroprosthetics, rehabilitation robots, humanoids, and human support robots.

Background/Objectives: The potential application of electromyography (EMG) as a method for precise force control in prosthetic devices is investigated, expanding on its traditional use in gesture detection. Variability in EMG signals among individuals is influenced by physiological factors such as muscle mass, body fat percentage, and subcutaneous fat, as well as demographic variables like age, gender, height, and weight. This study aims to evaluate how these factors impact EMG signal quality and force output. Methods: EMG data was normalized using the maximum voluntary contraction (MVC) method, recorded at 100%, 50%, and 25% of MVC with simultaneous grip force measurement. Physiological parameters, including fat percentage, subcutaneous fat, and muscle mass, were analyzed. An extreme gradient boosting algorithm was applied to model the relationship between EMG amplitude and grip force. Results: The findings demonstrated significant linear correlations, with r2 coefficients reaching up to 0.93 and 0.83 in most cases. Muscle mass and fat levels were identified as key determinants of EMG variability, with significance coefficients ranging from 0.36592 to 0.0856 for muscle mass and 0.281918 to 0.06001 for fat levels. Conclusions: These results underscore the potential of EMG to enhance force control in prosthetic limbs, particularly in tasks such as grasping, holding, and releasing objects. Incorporating body composition factors into EMG-based prediction algorithms offers a refined approach to improving the precision and functionality of prosthetic control systems for complex motor tasks.
