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.

Wow, that is so cool! I took a couple of classes in kinematics and motion of machines 50 years ago. I cannot imagine how you would begin modeling that motion.
We’ll probably begin seeing robots with smooth, human-like motions.
😉😎......................
The only caveat is that your IT Department will have to give a few thousand dedicated (yet kept secret) IP Adresses for each axis for each machine in the entire factory. I had one machine with over 1,700 IP Adresses and 1,150 Axises to control. Cabinets and racks as far as the legs could carry me.
The most common downtime cause was when Kinetix and Poweflex would hit on duplicate IP Addresses. Some nitwit in an office would install his new printer or massaging chair and they would let an "install wizard" program snatch up an IP Address already in use. It may take an hour, day, or week, but when those duplicates check in with the master, you're going down bigly. Then it takes days to find the unauthorized device on the network.
Well, thanks for the apology, if you feel it’s needed. But I don’t recall the incident...
Superb engineering!
“Well, thanks for the apology, if you feel it’s needed.”
It was definitely needed. :)
humm. looks like man trying to copy God again. good luck man (you’ll need it).
Thanks for sharing that, that is incredible.
That is wild!
Jamestown1630, this is obviously a very insincere apology, and I recommend you reject it utterly. The only thing that can make things right is a cash settlement of WELL over six figures, and a hot blond co-ed's ministrations as well. Hold out for better things, do not take the first offer from him. I can serve as a kind of arbitrator (for a small 33% fee of course.) Please call me immediately at 1-800-CASH COW.
Hear Hear........ applause for a sincere apology
Lol... :)
It was right. We only have right or wrong in this world. :)
For numerous reasons, I don’t think I’d be interested in a ‘hot blond co-ed’.
(I hope you’re staying dry.)
Mine rotted out at the floor. New England weather. But, the only good use for the Boston Sunday Globe…lay it over the hole and it would keep me dry until Spring. Only $1.00.
