Review Questions

• How do pneumatic systems utilize the principles of fluid mechanics to create motion in robotic applications?
  • Pneumatic systems rely on the principles of fluid mechanics, specifically the behavior of gases under pressure, to create motion. By compressing air, these systems generate force that can be directed through actuators to produce movement in robotic arms or tools. The ability to quickly release or adjust the pressure allows for precise control over motion, making them vital in robotics for tasks requiring speed and flexibility.
• Discuss the advantages of using pneumatic systems over hydraulic systems in industrial robotics.
  • Pneumatic systems offer several advantages over hydraulic systems in industrial robotics. They are generally cleaner since they use air instead of hydraulic fluid, which can leak and contaminate the environment. Additionally, pneumatic systems tend to have a higher power-to-weight ratio, allowing for lighter and more efficient designs. Their ability to operate effectively in extreme temperatures also makes them suitable for diverse industrial applications where hydraulic systems may struggle.
• Evaluate how advancements in technology have impacted the efficiency and precision of pneumatic systems in robotics.
