The ABENICS active ball joint gear allows for extremely precise, high-torque movementYamagata University
At its core, this system developed at Yamagata University in Japan uses a "simple" cross-spherical gear paired with a monopole gear to control pitch, roll, and yaw. Essentially, the same full range of movement you'd see in a rotator cuff (the shoulder) of a human. With clever gearing, coupling, and sliding motions, the ABENICS gear is extremely precise in its movements.
By adding a second monopole gear and differentials in tandem, connected to a ball joint, this system becomes even more robust. Operators are able to achieve very precise, high-torque movement on the spherical gear with incredible accuracy.
If attached with an output link – like an arm or a leg – this means finite control over a very realistic joint in robotics for smooth and natural movement. Generally in today's humanoid robots, two or more motorized joints are used in tandem for a shoulder: one to control up and down, one for forward and backward motion, and a third to control rotation.
ABENICS – Active Ball Joint Mechanism With Three-DoF Based on Spherical Gear Meshings, as it's officially called – could simplify these joint structures, combining a full range of motion into a single joint.
ABENICS can roll, pitch, and yaw in every direction Yamagata University This type of gear hasn't been widely adopted in any commercial, medical or industrial ventures as of yet. Although its focus has been mostly in academia and research, the technology shows very high promise for future use in areas where high torque, high precision, and three-dimensional freedom of movement are needed.
The implications of what robots equipped with ABENICS joints could do are boundless.

Ping!..................
Ok, that is seriously cool...
I wish I had those for my ‘66 Dodge Dart. The ball joints were a weakness of old Mopars.
Bump
Nice! I’m looking forward to getting 4 installed in my old age.
wow!
Read later.
One motor with one output shaft connected to a dozen or so mechanically linked gearing applications has always been a hard crash disaster setup IMHO. To me this seems like a step backwards in technology.
The minds of Asians are....interestingly different.
This system appears to be the very definition of single point of failure.
The 2035 sex doll models are going to be great.
That ball reminds me of the initiator in early nuclear bombs.
If you are going to stick it is for joint replacement, how do you keep all the body pieces out of the works?
“I wish I had those for my ‘66 Dodge Dart.”
My Dart kept eating the limited slip rear end.
Apparently a special small diameter design for the Dart.
yes they will use windshield washers for the hawk tuey action
Just looking at the cartoon, what if those precise looking gears go out of sync?
I think this will be for robots and articulated arms, not human knees.............Although that would be fascinating..................
Looks like a high wear system..............
Hey... There you are. I have been waiting for the chance to give you a very much deserved public apology. Several days ago I somehow in my old mind mixed your username up with someone elses I feud with, and I was rude to you and used some very disrespectful and insulting language. I thought you were being rude to someone and mistook your intentions and reply. My kneejerk reaction was completely in the wrong and I am hoping you might forgive me. From the bottom of my heart I do apologize for being an idiot. :)
