De-mystifying Engineering using bite-sized videos.
I take on a topic heads-on and break it down into digestible chunks for you to follow along and learn. It's simple, straightforward, and no-rocket science.
Mr. Zain, I'd like to first thank you for sharing your knowledge and dedication to make videos with such great quality, I'm sure it takes a lot of hard work to produce. If I may ask you a question, I'd like to understand why at 7:21 is ɣ +- Cos^-1(15/√ (15/(18^2+6^2))) The "+ -" is the only part I did not understand why (could not find a trigonometric for it) Thank you in advance.
Hi, why call the linear transformation such as homogeneous transform? Homogeneous can be a linear system AX=B B = [0 0 ... 0], but the transformation is only a function. However, thanks for this playlist is so useful.
Thanks for making these videos! Really appreciate it! You have a great way of teaching and presenting information in a logical way, it makes difficult concepts easy to digest :)
Hi man I have an exam coming up. We need to understand ch 3 4 and 5 of our syllabus . This entails implementing the Jacobian as well as Lagrangian Mechanics for a 2 dof .
Such a nice video, thanks for elbroating in detail about the each equation. We can use a fsolve in python to easily solve this equation, with guessess. Thankyou for your video
hello i would like to point out that you didnt mention or draw out where is the object in the end effector frame so how can i assume that it is at the origin of the end effector frame? perhaps i misunderstood somewhere
Hi. Just found this.. Great to see the way this is presented. However have a little problem with maths. You square 2c(Theta1+theta2) and add to square of 2s(Theta1+theta2) shouldn't the answer be 4 (c2(1+2)+ s2(1+2)) not 2(c2(1+2)+s2(1+2)
Hey, I'm a high school student and I'm very interested in robotics. I have quite a few projects in my channel as well, if you want to see. coming to the point, i wanted to level up my robotics and get into biped, quadrupled, walking robots, balancing robots and stuff. So I wanted to learn robot kinematics and dynamics and pid control, etc. How would you recommend to go about this and making my robots with full understanding of each and everything i'm doing in my robot (i want to do this the hard way since i don't want to just copy someone else's open project, rather i want to learn and understand it fully) Please suggest a roadmap to be capable of building my own biped robots from knowing almost nothing.
i have define the small x in m2 frame similarly define with the m1 frame. both are respect to the fixed frame, but i dont get the final equation like you, what is the actual method two do more than two frame?
hello sir amazing video, i am having trouble understanding as to how do you get the values for the displacement. can you just explain me the method for calculating the displacement value for the matrix?
great video, but I found a problem with the calculation for theta 1 when using l2a, I get different answer when I calculate, although I am using same equation, I get theta1 =15....am I doing something wrong?
Hi, I am getting the same result, I've checked with a scientific calculator and online. theta1 =+15º and theta2 = -75 º(same as the video) Probably a mistake I am also confused on the representation of the positions, the video seems to not follow the same pattern as the previous ones (11:50 the angle of theta2 = 135 is confusing, it should go to the pink line as it's for the solution 2) If I may ask, did you understand that part? Maybe I missed something, I have taken notes on all the previous videos and checked them, but still confused.
@@Captain_Vitorio_Muscovy to be honest this replay was 4 months ago so now I don't remember anything, and that is a problem because I have midterm on this topic in 1 hour 😅🤣
