ABENICS (Active Ball Joint Mechanism With Three-DoF Based on Spherical Gear Meshings) is a ball joint system which uses a cross-spherical gear in conjunction with a monopole gear in order to be able to manipulate the spherical gear in three dimensions of freedom (pitch, roll, and yaw). Adding a second monopole gear makes the system more robust and capable of highly accurate movement with high torque.
|
|
The spherical gear is essentially a pair of 2D gears which have been rotated around their axes, resulting in something resembling a golf ball.
|
|
Potential uses include any situation requiring accurate, powerful control over three degrees of freedom, such as in replication human joints.
|
|
The design was published in IEEE Transactions on Robotics in October 2021.
|
|
The mechanism has been replicated using 3D printing by enthusiasts.
