Variable stiffness actuators can dynamically adjust output stiffness to accommodate varying task demands, making them well suited for grasping applications. Nevertheless, conventional variable stiffness actuators often suffer from bulky structures, slow response, and complex control, which hinders t
Gravity compensation has been widely employed in lower limb exoskeletons to reduce leg load and alleviate muscle fatigue. Passive compensation approaches offer inherent safety and lightweight advantages; however, existing designs are often constrained by the bulk and complexity of spring-based mecha

Gravitational loading from a transradial prosthesis imposes continuous mechanical stress on the residual limb, potentially causing discomfort and even prosthesis rejection. This letter presents the Floating Prosthesis, a wearable passive exoskeleton designed for gravity compensation (GC) in transrad
Assist-as-needed (AAN) strategies aim to enhance active participation, thereby promoting neuroplasticity and facilitating motor recovery. However, due to variations in injury severity and motor abilities, non-adaptive AAN control strategies may provide suboptimal assistance. This letter proposes a t
In the force feedback of physical human-robot interaction, stiffness is rendered to represent the hardness of the manipulated object, aiding users in executing accurate maneuvers. Active feedback based on electric motors usually cannot simultaneously achieve both high force and high backdrivability,
