SUMMARY

This discussion focuses on designing a four-bar linkage claw specifically for underwater applications, intended to grasp a submarine. The user has shared initial designs, including the lengths and positions of base pins for the claw's open and closed states. They are also calculating the dynamic forces acting on the claw's links and pins during operation. The user seeks feedback on their approach and additional literature to enhance their design process.

PREREQUISITES
  • Understanding of four-bar linkage mechanisms
  • Knowledge of dynamic force calculations in mechanical systems
  • Familiarity with underwater robotics design considerations
  • Proficiency in CAD software for mechanical design
NEXT STEPS
  • Research four-bar linkage design principles and applications
  • Learn about dynamic force analysis in underwater environments
  • Explore CAD software options for simulating mechanical designs
  • Investigate existing literature on underwater robotic grippers
USEFUL FOR

Mechanical engineers, robotics students, and designers working on underwater robotic systems or gripper mechanisms will benefit from this discussion.

Hello All,

I am working on a final project for class, and I am trying to design a bar linkage claw design like the one I have attached. I have also attached my attempt to design the length, and where the base pins are supposed to go for the desired start and finish position, open and closed, of the claw. I want to make sure I am approaching this the right way. The claw will be holding a submarine. I have also attached my approach to calculating the dynamic forces that the links and pins of the claw will experience while traveling under water. I realize that I am missing key things like length and angles; this is just a start I want to make sure I am approaching it the right way. Any help or comments that might help me will be greatly appreciated. If there is literature that will help that would also be greatly appreciated.

Thank You
