- I have build very unusual Robotic Arm. Its unique design allows for the organic motions, which are not accessible to other robots. Here the link to the controller used (it's super new!!!):

In order to finance my RUclips channel and my projects, I am starting the consultation in robotics. So if you would like to ask me questions about my builds (or about your projects) you can do this through my website ( www.skyentific.com/book-online ). This service is not cheap, because I would like to limit it (with lower prices I would have to do this all day long, and I would not have time for projects/RUclips). And of course, I cannot guarantee that I will be able to help you during this consultation, but I will do my best.
The inverted movement reminds me of GLADOS. Cool concept, thanks for sharing!
Remember, the cake is a lie!
This is a fantastic way to teach the concept of adding degrees of freedom incrementally to an initially simpler setup.
Watching these videos is definitely a highlight of my day. Always impressive seeing 3D printing used in such a versatile manner
Spoiler : I watched this whole video, that robot does not roll a joint. Much sad, very disappoint.
Add fingers in the next update
Я даже не сразу врубился, что видео на английском языке)) Русская речь на английском языке))) мне понравилось, спасибо!
Для увеличения жёсткости стоит добавить продольные рёбра жёсткости.
One of the chief drawback from mechanical point of view is that at specific angle in 3d coordinate, there will be excessive torque needed for delta movement. Similar to knuckle joint strains at 45°
If it were constrained by an extra armature, it seems it could be used as a constant velocity joint. But again it may be limited by torque loading... However I wonder if that could be worked from the other direction by using a CV-joint design that handles torque well as a robotic armature if it's not constrained like it would be on a vehicle drive line?
@@pauljs75 I liked the counter idea, its an idea worth exploring.
could someone explain this but for dummys? (me)
@@keixsy The design allows angles with lots of stress against specific joints. I.E. too many hard materials to flex and distribute the stress accross the entire structure.
@@pauljs75 look up the Thompson Coupling from Australia.
That has got to be the absolute coolest robot arm I have ever seen!!! Now I want to print my own, lol. Thanks for sharing.
Your test at 17:00 is the money shot! That's the one I was waiting for - stable platform rotating is sweet! Well done!
Thank you so much for depicting your wonderful project. Your work and effort are oustanding. Your movies have been providing excitement and inspiration for so many years. Thank you again!
Thank you for the effort in explaining the concept in the beginnning.
Fascinating point you made that because you're using three motors for two degrees of motion you can use the servos to eliminate backlash. Also like how this design lends itself to easy cabling. Very cool. Thanks for sharing.
This is a great demonstration of inverse kinematics as well.
Brilliant, as usual. Love watching your work in Robotics!
Beautiful and magnificent. I can't believe I've never seen anything beyond the literal rolling joint - with the cables/strings and also only with one axis. These multi-axis rolling joints are awesome. Great stuff!
This is really high quality and informative. People like you make the internet awesome. Subscribed!
Thankkk uu for all your sharing with us ❤️🌹❤️
The biggest drawback of the “quaternion joint” is that it’s not actually kinematically defined with true rigid bodies. It relies on tiny amounts of joint slop and elastic deformation to act as a joint.
I'd love to see how you worked out the inverse kinematics for this thing. That would be a great video on its own. These spherical parallel manipulators are just so mesmerizing to watch. They remind me of a delta 3d printer in some ways. Beauty and engineering. Well done. I think it'd be cool to stick a 360 lidar on the top of one and use it for slam mapping in 3d.
Literally the most fascinating mechanism I've seen in ages.
Can't wait for further development on this arm. Please keep up the good work
This is amazing. Craziest joints I’ve ever seen.
Great work! Seeing this illustrates just how much of an engineering leap it is to go from this to factory level robotics to Tony Stark style concepts.
Amazing !! Great ingenuity and craftsmenship !
Love it, love it, love it. You are doing a great service 😊
Extremely cool concept and design. I could definitely see this design in usage for deep sea/space exploration scenarios.
Very cool design!! Love it!
It's just brilliant
Thank you for this very interesting video.
One more epic, thanks so much for bringing us this 👍
bloody AWESOME!!!!
Super Cool!!
very organic moves, a joy too see :-)
What an interesting design- thanks for making this video.
What an amazing project!
Fabulous!
Very nice project, very interesting for solar's panel purchasing applications, congrats
Super cool. Thanks for sharing
That's a very cool robot arm! It looks elegant
joint looks cool
Super cool!
Brilliant design and execution!
I watched a video about rolling joints and didn't even learn how to roll a single one.
Kidding, this is a really cool mechanism. Thanks for putting this video together! :D
keep up the awesome work your stuff never ceases to inspire :)
beautiful!!
Wow. Very nice work 😳💪🤟👌
Incredible, makes me want to step up my 3D printing game!
This video is absolutely amazing!
Excelente video. Muchas gracias. Saludos desde Argentina
Need... more... degrees of freedom...
This has been great, thanks for letting us into your dev process 😁
very lovely mechanism!
Very nice design, love it
Very nice!!
Brilliant.
Awesome!!!
Perfect for sun tracking!
Thanks
Cool project! Nice work!
TYVM for the brilliant lapel mic, your audio is superb!
these are really diferent ways to make joints !!! amazing sir
Super works. ..!!!
you are a genius
Beautiful mechanism. Rigidity/stability will be the biggest challenge.
You always have great videos. This is a cool and unique design. Great work and thanks for sharing it with us.
wonderful video.
Excellent video!
This is AMAZING!!!
Very interesting !
This is awesome! It’s like a mechanical elephant trunk. It’d be awesome to see 10 of these joined together getting progressively smaller by a factor of 1.618. I’d love to see this in 6061 aluminum with the proper power and servos. This arm would be extremely helpful in space on the ISS or on a moon base. Imagine it on an automated gantry that can move in x y and z. It could put together entire habitats and move parts etc.
Super cool! thanks
Perfect Russian accent
Прикольная самоделка👍
Very cool board
Brilliant
Incredible... Only yesterday I thought about 2-dof joint realization..
Definitely one of the coolest channels on youtube
wow, thats pretty cool. nice work
Excellent CAD (Cardboard Aided Design)
Really cool! You could add another DOF by putting the base on a rotating axis.
Thank you for explaining how it works. I hope you see success soon
That is really cool!
really good
Lol, I spent an entire weekend in Fusion 360 recently "inventing" this very same basic joint structure. It goes without saying that there is nothing new under the sun and brighter minds have usually tread the same ground. Keep up the great work and thanks for sharing!!
Also have a look at Mark Rosheim's Omni Wrist 3 mechanism.
@@dm5rkt Thanks! I just uploaded the concept I worked up. It moves in 3DOF, but would require linear actuation/artificial muscles to control. Not sure how practical. ruclips.net/video/oOC0FxmM4WA/видео.html . If you have seen my concept worked out further somewhere, let me know. I am not trying to be original, lol. Just want a compact solution for a "shoulder" joint. Of course my joint suffers from multiple positional limitations.
Very fascinating ♥️
great job!!!
Very interesting design.
Fractal design! A larger one for the upper arm. Smaller one of the wrist. Even smaller still for a set of fingers!
i like it! im sure it will lead to something very unique and useful
Looks cool and very clever
интересно у вас получается объяснять 👍
Very f'ng cool!!!!
This, scaled down, would make for a fantastic animatronic puppet!
Very interesting design for the wrist joint of the robotic arm. I wish, I saw this video, before starting making my own robot.
Very interesting! I am sure there are many uses for such a link.
Woooa! Maravilloso
Amazing! :O
bravo!
Great !!!
Very cool robot
Thank you a lot!
Amazing
