Review Questions

• How does the impact resistance of polycarbonate enhance its effectiveness in underwater robotics?
  • The impact resistance of polycarbonate plays a crucial role in underwater robotics by protecting delicate components from sudden impacts or pressure changes. This durability ensures that sensitive electronics remain intact even in challenging environments, reducing the risk of failure during operation. As underwater robots often encounter rough conditions or collisions with obstacles, using polycarbonate helps maintain their functionality and longevity.
• In what ways does the optical clarity of polycarbonate influence the design of underwater cameras and sensors?
  • The optical clarity of polycarbonate significantly influences the design of underwater cameras and sensors by allowing clear transmission of light without distortion. This feature is essential for capturing accurate images and data in aquatic environments where visibility can be limited. Designers can rely on polycarbonate to maintain image quality while creating robust housings that protect against pressure and impact.
• Evaluate the importance of UV stability in polycarbonate materials used in underwater applications and how it affects long-term performance.
  • UV stability in polycarbonate is vital for underwater applications because prolonged exposure to sunlight can degrade many materials, affecting their structural integrity and performance. For underwater robotics, where devices may surface intermittently, ensuring that polycarbonate retains its strength and clarity over time is crucial. This characteristic allows for extended operational life without significant maintenance or replacement, ultimately enhancing the reliability and efficiency of underwater systems in various conditions.
