Triboelectric nanogenerators (TENGs) represent a promising next-generation renewable
energy technology. So far, TENGs have been successfully used as highly sensitive and self …

Novel compliant actuation systems have been developed in recent years for a variety of
possible advantages, such as establishing a safe human–robot interaction, increasing …

High speed legged locomotion involves high acceleration and extensive loadings of the leg,
which impose critical challenges in actuator design. We introduce actuator dimensional …

In this paper, a new actuator with adjustable stiffness (AwAS) is presented. AwAS is capable
of controlling the position and stiffness of a joint, independently. The proposed actuator can …

This paper presents the development of a novel adaptive wearable ankle robot for the
treatments of ankle sprain through physical rehabilitation. The ankle robot has a bioinspired …

The paper deals with the possibility of replacing a mechanical planetary gear system by a
magnetic planetary gearbox. The magnetic planetary gearbox has many advantages such …

This paper presents a novel rotational serial variable stiffness actuator (SVSA) based on an
Archimedean spiral relocation mechanism (ASRM), which is applied to linearly change the …

This paper considers the analysis and application of magnetic gearbox and magnetic
coupling technologies and issues surrounding their use in high performance servo control …

For tasks that require robot-environment interaction, stiffness control is important to ensure
stable contact motion and collision safety. The variable stiffness approach has been used to …

In this paper, an adaptive fault-tolerant method is proposed to synthesize a compensation
controller for the uncertain nonlinear pure-feedback systems possessing dead-zone …
