#Robotics #Robot #RobotArm - Наука та технологія
This is unusual video for me. I hope you will like it. Anyway, I am not planing to do many videos like this one.
I enjoyed it.
Unusual? Maybe.
Informative as always? Definitely.
Keep up the great work!
if it is robotics it is entertaining! you can't always have a new motor or arm in every video, unless you're a millionaire haha
that robot is rubbish ... it is the design of a Chilean robot from 1980 ... they copied the transmission system and passed it through something new 2020...
And also the air muscle and the contractile gel to electricity that now they pass it for something new and they spend millions of dollars and they were really invented by some school boys
If you have a great idea and are a genius, you will quickly see that your ideas are stolen and another human appears with your idea and this guy will have a million dollar grant from the state to research ... but because they are thieves of concepts, the ideas can't move forward on projects ... they get stuck
it`s okay very informative keep going, by the way; I made my DIY robotic arm in my channel if you like to show it
Great breakdown and concise analysis, a very useful primer on the current state of robot arms!
I liked the way you compared the arms! It was interesting and informative. Keep up the good work!
Great analysis! I was looking for such! Thank you and keep on with analysis of mechanical designs of robots!
As medicine student with automation and cnc as hobby. This was a very interesting video. Thx for sharing :)
Great job describing the different clever designs for the arms. I always love to see how these challenges are solved. I would suggest that you also take a look at some of the various prosthetic arms out there as well.
It's amazing. Theoretical videos quite helpful in case of understanding robotics. Thanks for sharing your knowledge.
Great and deep explain and analysis. Thanks a lot!
Discovered LIMS2 some time ago. IMO it's the most promising design out there and if the production and assembly could be simplified it would have a lot of potential as a commercial product.
I don't think LIMS2 can really do "high five" since it only has three fingers (according to the schematic) but "high three" :D
You right! :))))
Lmao
😂😂
sure it can the other two are the middle ones I'm sticking up at you for making that joke before I could
Nice video skyentific!!, :D the advantage is the number of movements of the first robot, but the rope mechanism makes it less precise and that it generates oscillations when the sea load passed, in my opinion
very nice doku with a lot of work done by you! Nice! TOP! Very good work!
Very interesting, your projects are like adventures ! exciting !
Thank you very much!
Wow! Thank you for sharing !
Thank's friend, i did enjoy this video very much!!!
I'm learning mechanic design！This video is really great and awesome！Thank you so much❗️❗️❗️❗️❗️
What are you using to learn ?
Halodi Robotics is the company. EveR3 is the robot. And the Revo1 direct-drive motors are what they use.
What is interesting is the counter-tensioned
synthetic rope-based transmission which is actually part of the motor itself
Great overview!
I loved this vid, and agree about Blue and LIMS2, didn't know about the Halodi and it was very interesting!
Great video. Thanks & keep going
Thanks for sharing. It helps a lot.
Great Video, love it! :D Thanks
Гуд! Ай стартед фоловинг ю!
I'm wating for new videos, it's so good, congratulations
Thanks for another great video! I am learning so much from you. I have a general question (not related to this vid). What is "backdriveable" and why is it good and important? I assume it means "you can twist the joint or end effector that we're talking about and the force will transmit back through the transmission and spin the motor/source of torque" or something like that. Does it have anything to do with the elecrical system's tolerance of back EMF, or just the low internal friction of the system, or ??? Thanks!
Well done nice info!
Thank you!
Great short analysis and compare this example of 3 robot arm.
Thank you, always interesting :)
Sherlock Holmes over here!!! Next level investigating! Love the videos!
an excellent informative video.
This is a very good and informative video
I wouldn't mind seeing more videos like this.
Interesting, thank you!
Excelent Video ,, Thanks Sr
Yesss, I like the video ! I like all your videos ;-)
Excelent very good investigation. Good reference to Blue is AR3 mabye. I thing 1-2kg of manipulation weight is relative enough for manipulating with object. Stronger start to be expensive especialy if you want to use 2 hand.
Great video.
Greetings from Peru.
thank you!
Very good video, thanks for the content. I am an electrical engineer and now I would like to start building physical things (electromechanical). I do not know where to start. Would static and dynamic mechanics be a good starting point? Thankyou!
thanks for your video.
im a student in Vn.
good stuff
That Blue arm looks really cool.
100% agree!!!
thanks for this information...........
This is one of the best video
Thank you! I am very happy to hear this!
@@Skyentific hi sir I like ur videos bcoz it will teach how to use simple motors for complex function
I like your work very much, I want to know what software your CAD uses.
Thank you. Fusion 360
I would love to hear your thoughts on one of the Festo robotic arms. BionicCobot using pneumatic semi rotary drives or airics arm with air muscle.
Welcome back Professor.
We have not seen a new video in a couple weeks.... I hope all is well with you and your family!
Excelente me interesa aprender gracias por el video
Very interesting discussion on how the different teams approached the challenge of building a robot arm. On a different note, I'd like to ask, Skyentific or people in the comments, if one could use ODrive, as any ESC, for applications such as e-bikes or quadcopters.
I've not heard of anyone doing it, thought I imagine you could do it, however it would likely be overkill in both price and processing power
@@matt_the_schu You are probably right. Though I don't know of many reversible or programmable ESCs that can handle this high voltage and current at this price point (especially if one needs to drive a multiple of two motors). VESC are not very cheap either. Do you possible know of an alternative? :)
@@dempa3 I don't know too much about e-bikes, but for multirotors you don't really need something like O Drive, there are many fairly cheap ESCs you can buy that work well, unless you're trying to lift a huge amount of weight. I don't know too much about high-power ESCs though sorry :(
Блин, очень круто, ждем реализации)
I also noticed that Korean robot, I think sacrifices the joint below shoulder is better, if you learned from Nextage robot
What do you think about haddington dynamics Dexter robot arm? Most of it is open source, much is 3d printed, high precision and it has force control. They have a very interesting position encoder by using FPGA to decode its data.
Спасибо большое за разбор. У LIMS2 дизайн мудрёный но, блин, красивый!
Tochno!
please periodically make a video from new achievement in tobots
Could you make a video more about the Blue grippers
thank you for the tips and tricks ,
by the way, I am confused about reverse kinematics, may you make a video about it ? as a tutorial I mean.
Замечательное видео. Спасибо
Mr Skyentific, Link for mechanical design papers please?
Do you need to order some kind of cable that is designed not to stretch, or do you just expect adjustments to keep the cables tight (which is reasonable for a hobby robot)? How much of an issue is stretch in cables?
linear industrial motors from Siemens, for example, which run on skids, what do you think of them as robo-arm drives?
the arm of the third robot if it is a straight position, I am developing a humanoid robot, which you can see on my channel on youtube, but if the first two robots that angle the arms catch my eye
did Halodi publish some new information about their direct drive frameless motors? Have you tried to reach out to them?
I love your brain!
Hi, thank you. Your Knowhow is great! Do you think thas is possible to produce a small robot for logistic apps and set-up low small units to CNC machine as like as Universal Robot do? Is it possible to find a good supplier in the international market?
Keep going
How call that program that you were using for model?
Can you please write that the Hollow shaft rotary encoder which you use often from where can be bought? Can i buy it from AliExpress?
I’m thinking about ball socket joints hinge with actuators
Where can I view a PDF document on Manipulator LIMS2?
I was inspired by the designs of arms similar to LIMS2 and Halodi to get the weight of the arm away from the end. I put the elbow motors (small steppers) on the opposite side of the shoulder pivot to act as a counterweight then use belts to drive gear boxes and a belt drive differential elbow joint.
ua-cam.com/video/BBzAGSlbDig/v-deo.html
I was also inspired by the Barret WAM, which uses cables in a Swiss Joint, but I found that too difficult to build with 3d printed parts.
Wow! This is great! Excellent design!
I would appreciate clarification of a term used in your Art: "payload"
I assume you mean the maximum mass that can be held and manipulated by whatever grasping mechanism terminates the limb, while the remainder of the limb can still move freely and without damage through its full range of motion.
It would help put this in perspective if you included a ballpark "payload" for a healthy human limb with the same proportions.
I hope to hear from you on this.
How/Where did you get the LIMS2 patent? Or how can I find it? may I ask.
In google. It is in open domain.
what is the name of the design program ?>
I've always called LIMS by pronouncing it as one word rather than an acronym, like limbs but without the b. Also is there any benefit to using a cable drive, like Halodi uses, if you're not going to take advantage of a block and tackle pulley system, like LIMS2 uses? I would imagine that using a toothed belt would be more beneficial for transmitting power from pulley A to pulley B, or do wires provide enough friction for that not to be an issue, like how a rubber V belt works?
Hello, author, may I ask how to find patents related to LIMS2？
this kind of video is much better than this 3D printed arm, they were too common
Круто! А где вы работаете? И где учились? Просто я сам иду по этому направлению!
Ну, товарищ! Что же вы? Перед тем, как писать, посмотрели бы его ранние видеозаписи) ua-cam.com/video/kieA54KSviQ/v-deo.html
P.S. Он, поляк.
can you use bevel gears in robot arms?
why are the not used more?
Of course, they use them a lot. Blue arm has nine of them.
They don’t use worm gears in robot arms. Because worm gears are not energy efficient (you loose a lot of energy on friction).
BROTHER can you tell me the model name of the MOTOR and DRIVER used in LIMS 2....
thank you ...
where i can see that pdf???
make the same video for boston scientific robots
LIMS2 is very impressive
Robot with cable will give problems in the field if a cable should break. Cables like to break .
a very informative video. Thank you. it would be better if you could add the price info. though, at least 1 of them was not on the market.
Thanks u
Хорошо, только одно небольшое замечание, если начал разбор с LIMS2, то его и надо было ставить в первый столбец таблицы... ;))
Блин! Надо все переделать! :)
@@Skyentific да итак хорошо получилось! Интересно.
What CAD software u use?
Fusion 360. I think it is the best.
@@Skyentific spasibo!
Could you explain why these motors are backdrivable?
sorry but the first patent (US 20180065243A1) gives me nonexistent, where did you get it? can you forward the pdf please? or is it protected by something?
Wow
Introduce me to a 6 DOF free robot with a lifting capacity of 5kg.
You can just read LIMS as 'lims', not 'L-I-M-S' - that's what the developer (Prof. Yongjae Kim) calls it
Thank you. Good to know!
Шикарный акцент ;)
как раз искал инфу про них.

Конечно в качестве использования в дальнейшем такой робот имеет право на существование.
НО Есть некоторые НО.
Первое Данные роботы не очень груза подъёмные. При перегрузке система очень не стабильна .
Второе не много задач в мире в которых нужно точное подобие руки человека.
Проще разделить по операциям задание, сделать две или три операции но простых и понятных с подтверждением выполнения задания на каждом этапе.
В быту и не только мы используем продукты которые имеют правильную геометрическую форму.
ЭТО во первых удобно и практично, а во вторых это проще в изготовлении.
