- This video explains displacement vectors, which express the distance between the centers of two frames.
Robotics 1 is a college-level introductory robotics class covering kinematics, motion control, and sensors and machine vision.

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.
Here to understand a 15 hour presentation in 15 mins thank you Angela📈
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!
I seriously learnt about this chapter clearly through your videos than the uni lecturer that teaches me this subject. thank you so much!
Your work is amazing, Thank you for explaining it very well.
Extremely well explained in very simple way.! Thank you very much!
I binged watch your entire series in two days
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.

Thanks so much to you for your effort on explaining the topics (robotics) more easily..
Thanks a ton angela you made my day.
understood the concept in less than half an hour.
explanation was like spoon feeding..
Thanks Angela for your excelent videos. You make it easy to understand.
Excelente explicacion. Super didactica.
amazing videos.. please more of that
So neat !
God Bless you!
thank you so much for doing this.
Why do we rotate the second frame by 45 degrees (top view diagram) while calculating the displacement vector?
how to find x,y,z resultant position of end factor?
thank you
cool !
I wish i was your student, my robotics knowledge would be over 9000
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 .
Are you thinking about how she got to a2*cos(theta1) and a2*sin(theta1)?
great great greaaaaaatttttt
You should be hired by the best universities that offer robotics courses
is displacement vector the same as translation vector?
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.

Hi
i am watching your videos and i find them so helpful :)
i have a question why d0_2 != d0_1+d1_2?
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!
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 :)
that moment when your a high schooler trying to learn about kinematics and you predict whats going to happen next
*Im a genius!!!!*
Would you please stop writing because you cover very important information on the display
