SUMMARY

The discussion centers on a novel 3D gear model designed for robotics, specifically the Abenics versatile active ball joint gear. This model is proposed for use as a shoulder joint in robotic applications. While the design allows for a ball to spin independently, concerns are raised regarding its practicality, as it does not connect to other components. The proposed solution involves attaching a shaft to the ball while limiting motion to prevent gear contact with the shaft, enabling two degrees of freedom plus rotational movement.

PREREQUISITES
  • Understanding of robotic joint mechanics
  • Familiarity with 3D modeling tools
  • Knowledge of gear design principles
  • Experience with robotics applications
NEXT STEPS

They say this could be used as a shoulder joint for robots. Mind boggling! I'm amazed this has been done in real life.

The model they show seems impractical to me. The ball spins in place but doesn't connect to anything. I guess what they would do would be attach a shaft to that ball, then restrict the motion so the drive gears don't contact the shaft. The ball would have two limited degrees of freedom then a third for the shaft spinning. Very slick.
