Review Questions

• How do robotic actuators contribute to the functionality of upper and lower limb prosthetics?
  • Robotic actuators are fundamental to the functionality of both upper and lower limb prosthetics as they provide the necessary movement capabilities. By converting energy into motion, these actuators allow prosthetic limbs to mimic natural movement patterns, enabling users to perform tasks such as walking or grasping objects with greater ease. The precision and control offered by robotic actuators help improve the overall user experience and adaptability of prosthetic devices.
• Evaluate the impact of different power sources on the performance of robotic actuators in prosthetic applications.
  • Different power sources, such as electric, hydraulic, and pneumatic systems, significantly affect the performance characteristics of robotic actuators used in prosthetics. Electric actuators are lightweight and compact but may offer limited power output compared to hydraulic systems, which can provide high force but add weight. Pneumatic actuators can be efficient for rapid movements but require a continuous supply of compressed air. Choosing the right power source is essential for optimizing the performance, weight distribution, and functionality of prosthetic limbs.
• Synthesize how advancements in robotic actuator technology might influence future developments in prosthetic design.
