Special Issue Information

Dear Colleagues,

Autonomous robots in biomedical and healthcare applications have the potential for rapid growth in parallel with technological advances in sensing, data acquisition, signal and image processing, actuation, computing-hardware and software, artificial intelligence (AI), and deep learning algorithms, including deep reinforcement learning (DRL). The encompassed sensors include both traditional and miniaturized wearable biosensors for physiological signals and those used for electromyography (EMG), electroencephalography (EEG), and electrocardiography (ECG). The potential applications include assistive living, rehabilitations, and mental stress detection and mitigation through interventions based on the use of human–robot interactions (HRIs) in healthcare facilities and hospital environments.

This Special Issue aims to publish a collection of articles representing the state-of-the-art and future trends in the development of autonomous robots in healthcare applications within the broader area of bio-inspired robotics and intelligent systems (b-IRIS), component technologies, and their integration. Potential authors are invited to contribute in the form of original research, theoretical developments, experimental studies, and reviews of the current status and future trends in the area.

The topic fits very well within the section of “Intelligent Sensors” given the focus on integration of sensing, signal processing, actuation, computing, and potential deep learning algorithms toward the development of autonomous and intelligent systems in healthcare applications.

Aiming at the crossing problem of complex terrain, to further improve the ability of obstacles crossing, this paper designs and develops an all-terrain wheel-legged hybrid robot (WLHR) with strong adaptability to the environment. According to the operation requirements in different road conditions, the robot adopts a wheel and leg compound structure, which can realize the transformation of wheel movement and leg movement to adjust its motion state. The straight and turning process of the robot is analyzed theoretically, the kinematics model is established and solved, and obstacle crossing analysis is carried out by establishing the mathematical model of front wheel obstacle crossing when the robot meets obstacles. To verify the analysis results, ADAMS software is used to simulate and analyze the process of robot running on the complex road surface and obstacles-crossing. Finally, a theoretical prototype is made to verify its feasibility. Theoretical analysis and experimental results show that the designed WLHR is feasible and has the stability of the wheeled mechanism and the higher obstacle crossing ability of the legged mechanism so that the robot can adapt to a variety of complex road conditions.

Due to the fixed size of the structure or the possibility of only simple manual adjustment, the traditional toilet wheelchair cannot easily be adapted to the size of the user or the toilet. In this paper, a planar two-degree-of-freedom parallel mechanism with coupling branch chains is proposed to enable both seat height adjustment and body posture adjustment of a toilet chair, solving the problems of posture adaptability between the user and the machine, and height matching in the process of using the wheelchair-assisted toilet. The model of the parallel mechanism was designed after analyzing the general rules of posture transformation in the human body before and after the toilet process, and the dimensions of each linkage were then determined according to the constraint conditions. By analyzing the degree of freedom, kinematics, workspace, singularity and position of the center of gravity, the rationality of the design was ensured. The weighted average function was used to find the optimal fixed point of the horizontal moving slider, and the actual trajectory at the end of the single driving mode was close to the ideal trajectory. The experimental results show that the adjustable seat height range is 290~550 mm and the adjustable angle range is 0~90°, which can enable disabled people to use the toilet independently.
