Energy saving in robotic and mechatronic systems is becoming an evermore important topic
in both industry and academia. One strategy to reduce the energy consumption, especially …

This work gives an overview of all types of constant torque mechanisms (CTMs) based on
both function and structure. Based on their architecture, they can be divided into five distinct …

The potential applications of constant-force mechanisms (CFMs) have increased in recent
years with the development of new designs. This paper focuses on the experimental …

Constant-force mechanisms are designed to keep a constant or nearly constant input force
along a prescribed stroke of the mechanism. The implementation of this kind of mechanisms …

In strength or resistance training, the patterns of movement of the load and the muscle
activation can be adapted to the training objective according to the muscle conditioning …

This paper is concerned with the presentation of a parallel compliance adaptation method
for systems equipped with rotary motion mechanisms towards obtaining energy efficiency in …

Nonlinear springs are beneficial for various mechanisms because of their tailored load-
displacement relationships. These can be achieved by utilizing variable transmission ratio …

This paper presents the design and experimental validation of two force regulation
mechanisms (FRMs) containing a translational cam and a rotational cam, respectively. With …

In this paper, we answer two interleaved questions. The first one is, having a redundant
serial manipulator with a given cyclic task, how can we benefit simultaneously from both …

Compliant elements, installed in parallel with actuators, potentially contribute to the energy
efficiency of legged robots. Nevertheless, finding the most appropriate compliance profile …
