So nice , this 2 hours playlist completes my University whole semester's lecture, with even more, clear explanation compare to my lecturer, so like it when I find it in my revision week
That’s a lot of effort really! It is sad that it does not hit the number of views it deserves. I wish you luck and I hope you don’t get discouraged 🙏🏼🙏🏼🙏🏼
Very well and easily explained. Thank you very much, your video has helped me with my exam preparation. I have a small question though. At 10:06 in the box, you have mentioned d(i) and theta(i) to be with respect to z(i). Shouldn't it be z(i-1)?
make one full video on DH table and transformation where value of ai-1 somethings like a1,a2 and value of di is like d1,d2 and angle alpha consists of -90 degree or +90 degree
I looked at this so many times now and I find the (i) variable confusing. For the first line: The definition for a(i-1) is Distance from Z(i) to Z(i+1) measured along the X axis. This would make Z(i) =1 and Z(i+1) = Z2 because i=1. Yet we are looking at the Z0 and Z1 axis? Why do we not describe the Y-axis at all?
hola profe, queria preguntarle como se acomodaria la tabla DH si hubiera una articulacion rotacional auxiliar, en otras palabras simples uniones donde no va un actuador, estan ahi solo para apoyar en el movimiento, un ejemplo seria el robot que escribe la hora, saludos
This video is simply wrong in many areas... revolute => di = 0 ? this is false. prismatic => theta i = 0 ? this is also false. Also, is there no effort to discuss axis labelling? this is literally half of what DH is about... there is no way to obtain the parameters properly without first correctly labelling the diagram. Nice try, but overly simplified. For example, z0 cannot be arbitrarily chosen like it is here. It must point in the direction of joint 1...
the labellings were done in his previous video. As for the di and theta i, I don't know if they are correct, I myself am attempting to understand this topic
Direct Kinematics II, II means part 2, there was a part 1 describing how to label axes. Also, z0 is pointing directly to joint 1. Try to pay a bit more attention before tearing someones video down. Why dont you explain to us why those first two things are false?

Any clearn and lovely explanation, other than this is impossible! Can't appreciate enough :)
EXCELLENT lecture!

Thank you very much
Wow man such an excellent lecture! So simple yet so effective!
Thanks a lot I have my exam tomorrow and this will surely help
bro your videos on basic of robotics are awesome.... please keep making videos....
Very effective. Im sure going to ace my Robotics course this semester
Thanks very much, underrated channel
V v useful. Thankyou for going through an example.
U r genius thanks for such a lovely video
Precise and neat explanation ❤️ thanks
It helped me a lot in my assignment. Thank you very much!!!!!!!!❤️
Glad it helped, all the best
Amazing video, well explained !!
very good explanation. thanks!
Clear cut explanation thank you ✨✨✨
Great explanation
clear and concise
Was very well explaned.
Excellent work bro.🖤🖤🔥
i have one example problem, will you be able to solve and post answers for it?
Clear explanation...thank you
Excellent explanation keep going sir...

Thank you sooo much🎉
Nice explanation 👌👌
And, now how can I convert the table into transformation matrices? Could you plz suggest any material sir?
Thank you very much!!!
now what wuldve you have done if d1 want included in the drawing? would di for axis 1 just be 0?
make one full video on DH table and transformation where value of ai-1 somethings like a1,a2 and value of di is like d1,d2 and angle alpha consists of -90 degree or +90 degree
Thank You brooo
u r the best
Would be great, if you create a video with a more complex robot (including intersections).

Why do we not describe the Y-axis at all?
because there is no variable in y-axis
hello mate...keep it up.

teta i for the last should be 90+teta 3. Proffesor is it correct?
good job🥰🥰
Why on EARTH would one use the SAME SYMBOL for link length and link twist? (Latin a and Greek α alpha)

Looks I am not the only one to spot errors in this video.

We are all here to learn... what are the corrections that you suggest and please share any additional resources.
thank you very much !!!
