Structure and Function of Ligaments, Tendons, and Joint Capsule

For vertebrates to achieve locomotion and to hurl objects efficiently, they must be able to develop muscular forces, store elastic energy in tendon, and then transfer this energy to the attached

Shorter heels are linked with greater elastic energy storage in the

The spring function of the Achilles tendon was evaluated using specific net work, a metric of mechanical energy production versus absorption at a limb joint. We also combined

Research on the biomimetic quadruped jumping robot based on

Here, a design concept and a control algorithm are presented that aim at enhancing the explosive force of quadruped robots during jumping by utilizing elastic energy storage components. The

Kinematic synthesis and mechanism design of a six-bar jumping

The energy stored inside the elastic components is constant, and most of the existing jumping robots cannot control the take-off velocity [22]. Thirdly, the time gap of the

The mechanics of the gibbon foot and its potential for elastic energy

To estimate the potential elastic storage of energy in the triceps and digital flexors, we calculated instantaneous joint powers and positive and negative external work at

Increased force and elastic energy storage are not the

Joint moments, 198 joint power, and vertical COM power data were filtered with a 5Hz low-pass second-order 199 Butterworth filter. We then integrated joint power and vertical

The mechanics of elastic loading and recoil in anuran

This poses a challenge to elastic energy storage systems, which require some method to resist the joint torque and allow stretching of the

The effects of temperature on elastic energy storage and release

The elastic recoil mechanism in frog jumps is mediated by a dynamic mechanical advantage latch (a type of geometric latch), where the poor mechanical advantage

Evidence for a vertebrate catapult: elastic energy storage in

These supramaxi-mal power outputs are hypothesized to be the result of a catapult-like mechanism, which stores and subse-quently releases elastic strain energy [2–5]. A catapult

Design of the Jump Mechanism for a Biomimetic Robotic Frog

Moreover, the compact elastic energy storage and trigger mechanism is used to realize the complete jumping process of the robot, that is, elastic energy storage and regulation, energy
