Special Issue Information

Dear Colleagues,

The purpose of bionic wearable robotics is to develop advanced systems that augment human capabilities and assist individuals with mobility challenges. Inspired by their knowledge of bionics, researchers in the field of bionic wearable robotics have designed and optimized wearable robotic devices such as exoskeletons and powered orthoses, integrating innovative actuation mechanisms, sensors, and control algorithms for the disabled population. These wearable robots aim to enhance mobility, reduce physical strain, and improve quality of life for users with mobility impairments or those engaged in physically demanding tasks.

Assistive technology is designed to improve the quality of life of people with disabilities by enhancing their mobility, social interaction, and overall wellbeing. Different types of assistive technology and devices are available to cater to different disabilities. Some of the major types are assistive technology for people with disabilities, students, the blind, the deaf, and many more, while intelligent assistive technology (IAT) refers to the integration of existing assistive technology with artificial intelligence (AI) techniques and advanced environment interfaces. AI can be used to integrate a great deal of sensor information to amplify primary intent as well as to conduct background tasks, and intelligent assistive technology can be used to improve the performance of bionic wearable robotics in both sensing the environment and understanding the intention of users.

The application of exoskeleton robots has demonstrated promising effectiveness in promoting the recovery of motor skills in patients with upper limb dysfunction. However, the joint misalignment caused by rigid exoskeletons usually leads to an uncomfortable experience for users. In this work, an adaptive cable-driven elbow exoskeleton inspired by the structural characteristics of the shrimp shell was developed to facilitate the rehabilitation of the elbow joint and to provide more compliant human-exoskeleton interactions. The exoskeleton was specifically designed for elbow flexion and extension, with a total weight of approximately 0.6 kg. Based on the mechanical design and cable configuration of the exoskeleton, the kinematics and dynamics of driving cables were analyzed. Subsequently, a PID-based control strategy was designed with cable kinematics. To evaluate the practical performance of the proposed exoskeleton in elbow assistance, a prototype was established and experimented with six subjects. According to the experimental results, the measured elbow joint angle trajectory is generally consistent with the desired trajectory, with a mean position tracking accuracy of approximately 0.997, which supports motion stability in rehabilitation scenarios. Meanwhile, the collected sEMG values from biceps brachii and brachioradialis under the exoskeleton condition show a significant reduction in average muscle activation by 37.7% and 28.8%, respectively, compared to the condition without exoskeleton.

As the end-effector of a humanoid robot, the dexterous hand plays a crucial role in the process of robot execution. However, due to the complicated and delicate structure of the human hand, it is difficult to replicate human hand functionality, balancing structural complexity, and cost. To address the problem, the article introduces the design and development of a multi-finger synergistic adaptive humanoid dexterous hand with underactuation flexible articulated fingers and integrated pressure sensors. The proposed hand achieves force feedback control, minimizes actuator use while enabling diverse grasping postures, and demonstrates the capability to handle everyday objects. It combines advanced bionics with innovative design to optimize flexibility, ease of manufacturing, and cost-effectiveness. Full article

The accelerating population aging and increasing demand for higher work efficiency have made the research and the application of lower-limb assistive exoskeletons a primary focus in recent years. This paper reviews the research progress of lower-limb squat assistive wearable devices, with a focus on classification methods, research outcomes, and products from both domestic and international markets. It also analyzes the key technologies involved in their development, such as mechanical mechanisms, control strategies, motion sensing, and effectiveness validation. From an industrial design perspective, the paper also explores the future prospects of lower-limb squat assistive wearable devices in four key areas: multi-signal sensing, intelligent control, human–machine collaboration, and experimental validation. Finally, the paper discusses future development trends in this field. Full article
