Review Questions

• How does limited range of motion affect the overall efficiency of industrial robots in automation?
  • Limited range of motion can significantly hinder the efficiency of industrial robots by restricting their ability to perform complex tasks. When a robot cannot move freely within its operational area, it may require additional movements or even repositioning, which increases cycle time and reduces productivity. Consequently, understanding these limitations helps engineers design robots that are better suited for specific applications while maximizing efficiency.
• What are some ways that engineers can mitigate the effects of limited range of motion in robotic systems?
  • Engineers can mitigate the effects of limited range of motion through various strategies such as enhancing the robot's design with additional joints or degrees of freedom, employing inverse kinematics for optimizing movement paths, or utilizing multiple robotic arms to cover a larger operational space. By strategically addressing these limitations during the design phase, engineers can create more versatile robotic systems that improve operational efficiency and task performance.
• Evaluate how advancements in haptic technology could address challenges posed by limited range of motion in telerobotic applications.
  • Advancements in haptic technology have the potential to significantly address challenges associated with limited range of motion in telerobotic applications. By providing real-time feedback and allowing operators to sense and manipulate objects remotely, haptic devices can compensate for a robot's restricted movements. Moreover, integrating adaptive control algorithms with haptic feedback could enable operators to better navigate within the robot's limited workspace, enhancing their overall control and precision while executing tasks in confined environments.
