- Denavit - Hartenberg (DH) Tables For Robotic Systems - Direct Kinematics II
This video discusses how the assigned frames to a robot system, can be used to create a DH (Denavit-Hartenberg) table. This is done by finding the values of the 4 link / joint parameters, that are used to describe the position and orientation of one joint, relative to another.

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
Any clearn and lovely explanation, other than this is impossible! Can't appreciate enough :)
EXCELLENT lecture!
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 🙏🏼🙏🏼🙏🏼
Thank you very much
Precise and neat explanation ❤️ thanks
Thanks very much, underrated channel
Great explanation
clear and concise
Wow man such an excellent lecture! So simple yet so effective!
Clear explanation...thank you
Was very well explaned.
Clear cut explanation thank you ✨✨✨
V v useful. Thankyou for going through an example.
very good explanation. thanks!
Excellent explanation keep going sir...
Thanks a lot I have my exam tomorrow and this will surely help
Excellent work bro.🖤🖤🔥
bro your videos on basic of robotics are awesome.... please keep making videos....
Thank you very much!!!
Very effective. Im sure going to ace my Robotics course this semester
Nice explanation 👌👌
thank you very much !!!
Thank you sooo much🎉
U r genius thanks for such a lovely video
Thank You brooo
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
Would be great, if you create a video with a more complex robot (including intersections).
u r the best
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)?
It helped me a lot in my assignment. Thank you very much!!!!!!!!❤️
Glad it helped, all the best
And, now how can I convert the table into transformation matrices? Could you plz suggest any material sir?
now what wuldve you have done if d1 want included in the drawing? would di for axis 1 just be 0?
hello mate...keep it up.
teta i for the last should be 90+teta 3. Proffesor is it correct?
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 love you
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?
because there is no variable in y-axis
good job🥰🥰
Mannnnnnnnnnnnnnnnnn, you just saved me from getting an F tommorrow. kabskbjdjkadkkjadfnadfj
Finalize the example you have started
Hanzhen harmonic drive gear , robot gear joint,
over 30 years experience
Why on EARTH would one use the SAME SYMBOL for link length and link twist? (Latin a and Greek α alpha)
Ελα ντε και εμένα με μπερδευε στην αρχή.
calm down brother

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