Two Link Pendulum State Space Model
Переглядів 3,2 тис.Рік тому
State space equation derivation of an RR robot manipulator (two link pendulum) from the dynamics equations. Uses basic two-variable state vector, then expands to four-variable. Caveat - I am not a nonlinear controls expert, so this is just my best guess; video was made per request. For more information on nonlinear state space, see electronics.stackexchange.com/questions/213674/state-space-mode...

Good explaination.I hope a code Matlab for 3 D Stewart Platform Robot for this video please
Well these are some examples here. It’s theoretically a lot higher dimensional space with more variables. From a men’s perspective its the girls hotness, craziness but also age, loyalty, and how kinky she is in bed
i finally understand this.. thank you. 🙏 except, do we *have* to express in terms of theta1+theta2?
For this method yes, because theta2 is how much the motor at joint 2 turned, but that is not the same as link 2 angle with the ground, because motor one is also turning, so add theta1.
@@roboticsandengineering i see... so this is also because we apply consecutive transformations? 😅 we apply rotation 1, and then apply rotation 2? and so rotation 2 is a rotation on top of rotation 1? so the angles add up together? thank you so much for the videoseries, and reply
@@Colonies_Dev Yes, that's correct.
po2,y is yp + rp*sin(theta_z - pi/6)
Hi Elissa, how are you? I really like her videos, they helped me with questions about sizing end effectors. I need your advice, I work at a KUKA robot integration company here in Brazil, we manufacture palletizing cells, I would like to create a program like KUKA.SIM to simulate my projects, this Kuka program is very expensive and I want to find it another solution. Which path do you suggest I take? A step-by-step guide to what I have to learn to create this simulation program from scratch. Thank you very much.
The steps to take are: 1) Go to cad.onshape.com/ and make an account. The paid account has better features than the free account, but you might be able to do a trial version or get your company to pay for it. 2) Download KUKA robot CAD files from www.kuka.com/en-us/services/downloads 3) Load and assemble them in Onshape as shown in the video above. 4) Build the robot cell by making parts in Onshape and arranging them as needed. Tutorials to learn the basics of Onshape are available here: learn.onshape.com/collections/onshape-fundamentals-cad 5) Load the robot into the cell and perform a reach analysis as shown in this video: ua-cam.com/video/0viZPZNJ5O8/v-deo.html
Thank you very much Elissa!!!
This feels bad knowing the average mean income in the US is actually 35k
Hi, do you mind explaning why 6:35 , the 1-1 is also a junk? Is it because 1,1 part is redundant?
It is because the z-orientation cannot be independently controlled. If there were three joints, than you would leave it in to have a 3x3 J matrix. But without a third joint, only x and y can be independently controlled, so you just need a 2x2 matrix.
@@roboticsandengineering Thanks
Can show how you get the 0.94, 0.34 etc
The theta listed should be 20 deg instead of 40 deg, that was a typo. Then cos(theta) = 0.94 and sin(theta) = 0.34
@@roboticsandengineering thank you
Very good
could you elaborate on why quintic yield less IK solution?
It appears that the set of rotation matrices about the different axes of a coordinate frame must be determined, taking the rotation of the frames in the same direction.
Thank you for the lesson. But are you sure you demonstrated rotations in right way? As I understood, each rotations should be performed relative to CURRENT coordinate system in each step, but you did all rotation relative to INITIAL frame. I will be glad if somebody corrects me!
roll-pitch-yaw is a fixed frame situation because all rotations are given relative to the world frame, the standard for airplanes and robot end of arm tools.
Thank you very much for the video. It is very helpful to my assignment !!!!!!! But kindly remind you that you got some mistake on the writing the symbol or notation. some +/- sign and 1 and 2 theta. I have gone through all the calculation so I verified carefully with your result. Of course, the mistake can be mine lol
can you do a simulink of 6 axis robot arm with a control system?
Thank you for sharing your knowledge ... So inspirational. Thank you again!!
Hi Sir/Mam I understood how to do it but at 5:26 I tried deriving using identities but wasn't able so is it possible to share the whole derivation so it could help us as I have an exam in this course.
I appreciate the video and you. Nice take on it and helpful.
please I need the book?
Robot Modeling and Control, by M. W. Spong, S. Hutchinson, M. Vidyasagar, John Wiley & Sons, 2006, ISBN-13: 978-0471649908
Excellent. Thank you!
You explained it very well. Can you also create a video about interpolation in trajectory planning using dual quaternions ScLerp? Thank you
Infinite, rather than infinity.
Thumb up, despite skipping over the tranny area. Neglecting to acknowledge its existence for men can lead to another level of disappointment. Also, women need to be aware there is no need to compete with that area, just match them halfway for craziness.
Thank you so much for the simple explanation!
perfect
Estou tentando achar um codigo que eu teria que clicar uma quantidade de vezes no butao (dentro de um espaco de tempo) para o led acender por uma quantidade de tempo
Code??!
Just search arduino toggle button
Are you demonstrating the power differences between ac and dc by pressing the two buttons?
No, it is showing the fan spin in opposite directions using an H-bridge.
@@roboticsandengineering what is an h bridge
Very nice explanation teacher
Good video
Ok.
Good video
Very helpful. Thank you for doing this.
mam can you please provide complete mat lab program for the given problem
no, code is proprietary
grate work mam
greetings to you mam ., excellent tutorial mam if possible can you explain same for varying velocity and acceleration
Velocity and acceleration are included in this video.
Excellent analysis 😂
thank you so much 😊
Sorry for the stupid question, but what is "s"?
If you mean in the equations, it represents sine (e.g. s_1 means sin(theta_1)). If you mean in the Simulink model, it is the frequency variable where s = d/dt or 1/s =integral(dt).
👍
Seen your videos earlier today. Impressive work. Keep it up !
Thank you!
this is so sweet
Excellent lecture. Clear and simple explanation. got the hang of it in one go. thank you very much.
Pretty great analysis. Going 3D. I liked it.
6:07 wtfffff I got jumpscared
8:26 You'll catch even more with manure. What's your point?
Manure is for sure a lucrative business, but this goes back to the 3rd axis dimension, personality. Honey would guarantee you're out of the jerk or pessimist zone, manure won't necessarily. You could still be a shitty guy.
Lol. That was pretty funny
Hello, for the coordinates of the origin, it should not be O_1 = (l_1, 0, h_1), 0_2 = (l_1 + l_2, 0, h_1) and 0_3 = (l_1 + l_2, 0, h_1 - d_3) ?
The coordinates of the origin change as the robot moves. The formulas you typed are correct for the home position, but as the robot moves, those coordinates change, so you must account for the joint motion.
Please give me a link to the technical data of this robot, I need the maximum and minimum values of thety, and lambdas please plis plis plissss
This is really helpful for me, thanks for reading the comment :D
Great expalination Professor!
