Question

PLEASE HELP

If you were a robotics engineer, how would you design a prosthetic limb that stretches and releases? Explain the different parts of your design. Think about the following elements in your design:

Apply the relationship between electricity and magnetism to design a simple motor.

Explain how the motor would cause the tendon to stretch and release.

Answer 1

The function of tendons can be classified into two categories: tensile force transmission, and storage and release of elastic energy during locomotion. The action of tendons in storing and releasing energy is mainly seen in sports activities with stretch‐shortening cycles (SSCs). The more intense the SSC movements are (jumping‐like activities), the more frequently tendon problems are observed. High SSC movements impose high loads on tendons. Consequently, tendons that frequently deal with high SSC motion require a high energy‐absorbing capacity to store and release this large amount of elastic energy. As the elasticity of tendon structures is a leading factor in the amount of stored energy, prevention and rehabilitation programmes for tendon injuries should focus on increasing this tendon elasticity in athletes performing high SSC movements. Recently, it has been shown that ballistic stretching can significantly increase tendon elasticity. These findings have important clinical implications for treatment and prevention of tendon injuries.

Summary:

A new surgical technique could allow prosthetic limbs to feel much more like natural limbs. Through coordination of the patient's prosthetic limb, existing nerves, and an artificial muscle graft, amputees would be able to sense where their limbs are in space and to feel how much force is being applied to them.
