[@nchimunyamuyuni7920]

Thats why I say teaching is a skill and not something you can automatically do due to having a doctorate degree. Thanks so much for the educational videos, I've literally learnt more from you than my professor.

[@gerhardmalberg4966]

Very valuable videos! I so much appreciate your work to make this all material. You explain robotics more practical way than any other and that's huge plus. I am happy I found your channel and videos. Keep it up excellent work!

[@shasivarma7425]

I seriously learnt about this chapter clearly through your videos than the uni lecturer that teaches me this subject. thank you so much!

[@SasteJugaad]

I binged watch your entire series in two days

[@mohankrishna2188]

Thanks a ton angela you made my day. understood the concept in less than half an hour. explanation was like spoon feeding..

[@MS-hb3ol]

Here to understand a 15 hour presentation in 15 mins thank you Angela📈

[@fernandocosteira7494]

Thanks Angela for your excelent videos. You make it easy to understand.

[@kumaranshu9180]

Thank you so much Maa'm _/\_. I have watched your video and now I am able to solve numercals of my subject. My semester exam is on 11th october and really it will help me a lot. I will be grateful to you. Anshu Kumar from Madhubani(Bihar) INDIA

[@muhammadbilalawan]

Your work is amazing, Thank you for explaining it very well.

[@sams-ingenieria]

Excelente explicacion. Super didactica.

[@sagu_eng]

Thanks so much to you for your effort on explaining the topics (robotics) more easily..

[@krishnasai1962]

Extremely well explained in very simple way.! Thank you very much!

[@NotSionnix]

i'm not sure I understand how you got a2cos(theta1) and a2sin(theta1) for d01 at 10:40. Could you explain that in a different way?

[@blankipv4]

cos(theta_1) = (X0_1)/a2 and sin(theta_1)=(Y0_1)/a2 from the triangle.

[@aishwaryab1492]

Why do we rotate the second frame by 45 degrees (top view diagram) while calculating the displacement vector?

[@afnan2658]

Thank you very much for the valuable explanation, I have a question at 9 mins what is the name of the phenomena that are used to find theta in a triangle with 90 degrees. I need to understand it well as basic .

[@fckyu5440]

Are you thinking about how she got to a2*cos(theta1) and a2*sin(theta1)?

[@retronexusio]

amazing videos.. please more of that

[@wheniambored3903]

how to find x,y,z resultant position of end factor?

[@necastavasbriga5989]

I wish i was your student, my robotics knowledge would be over 9000

[@knighttime19]

So neat !

[@nchimunyamuyuni7920]

You should be hired by the best universities that offer robotics courses

[@SaRa-vq7mk]

thank you

[@karlmurray5537]

God Bless you!

[@abdomastafa4244]

great great greaaaaaatttttt

[@yugansh.g]

thank you so much for doing this.

[@thubelihlenyathi2236]

is displacement vector the same as translation vector?

[@asodemann3]

I am not sure because I don't know what is meant by 'translation vector'. Is the 'translation vector' located in the 4th column, rows 1-3 of the homogeneous transformation matrix? If so, then yes, the displacement vector is the same as the translation vector.

[@mohannadaldakhil9068]

Hi i am watching your videos and i find them so helpful :) i have a question why d0_2 != d0_1+d1_2?

[@asodemann3]

That's a great question! You can't get d0_2 by just adding d0_1 and d1_2 because d0_1 is expressed in frame 0, and d1_2 is expressed in frame 1. Frame 1 can be rotated relative to frame 0. So, in order to add d0_1 and d1_2, you would first have to 'un-rotate' frame 1 so that it matches frame 0. That is what the Homogeneous Transformation Matrix does!

[@mohannadaldakhil9068]

i was looking for an answer what is the different between Homogeneous and normal Transformation i think this is the answer thank you and i will keep follow your videos :)

[@sihammohamed7480]

cool !

[@amazingannyoing1716]

that moment when your a high schooler trying to learn about kinematics and you predict whats going to happen next *Im a genius!!!!*
