Hello! Please can you make video on how much maths is required to understand robotics! I'm afraid that I don't know much maths so I to focus on maths first??

@@kartikeyyendhe1840 Hey! Robotics is a vast field so I can't say how much maths is required for everything. For the things that I am covering in this playlist (kinematics, modeling and design), you only need to know the basics such as matrices, derivatives, etc. Most of the maths will be performed on a software anyways such as MATLAB so don't worry too much over it. I would recommend that you start learning robotics and when you encounter a roadblock, pause and learn whatever is required to get over it and then move on. This way, you will only be learning the important and required maths.

Thanks a lot, Darsh. I am actually a *Pakistani creator currently living in Ohio, USA. I am extremely glad that you find these videos inspiring and I try my level best to explain them to the best of my efforts. New videos will be coming soon. Plus I am also building some robots so watch out for those videos as well!

This helped significantly!

Thank you so much! Glad you liked it.

Appreciate the content. When you simplify equations you use trig identities that you are obviously very familiar with, however your viewer may not be as familiar with the identity. Thus on future videos it would be helpful to folks like me to just name the identity you used. I found them all eventually but had to go searching to figure out your steps. The cos(gamma)sin(theata) identity took a bit for me to find. All still appreciated though.

Thank you for your suggestion! You do make a very good point. I will try to state out the identifies in more detail in my future videos. Have a great day!

It is great that you support your video with a Matlab application. I understood better with that software.

That's great! Yeah, supporting it with a software really helps to drill in the concepts. In my more recent videos, I have even started supporting the theory using robot simulation softwares so that you can see the robots move in 3D. One such video is my new videos in the robotics 201 playlist on Inverse Kinematics.

Hi, thanks a lot for the video! Did you use algebraic or geometric way of solving? And I believe your voice is just fine, 😅, please keep using it (saw a comment underneath)

Thank you so much wonderingslacker! I take comments attacking my personality very lightly. Regarding my way of solving, I always use the algebraic way simply because it is universal and can be applied for industrial 3D of robots as well. I don't know if you followed along with the series but later on, I show exactly how that is performed using homogenous transformation matrices.

what if my end point is fixed of a 3R object which has 3 links of length 3 what will be the value phi and also how do solve these equations using a software

@EngineeringSimplified

2 ай бұрын

Can you elaborate more on it? Is your end-effector's pose (position and orientation) pre-defined or is it fixed?

Can you do the same method for 5-DOF robot arm?

@EngineeringSimplified

9 ай бұрын

The methodology is exactly the same. Give it a try on your own and let me know if you run into any trouble.

why is theta 3 not the same as the position of the end effector?

@EngineeringSimplified

7 күн бұрын

The reason that theta3 is not the position of the end-effector is because theta3 is defined from the link2 of the robot. Think about it in a practical way. Let's say we have a motor attached to link2 and you have to rotate the motor, you will tell it to rotate by 'x degrees'. This will be from the link that the motor is connected to and not from the ground (fixed frame). Based on this, the end-effector orientation is simply the sum of all angles of the links which in this case is 'Theta1 + Theta2 + Theta3'. I hope that helps answer your question.

i got the problem when the unknown variable is more than the equation itself (the equation only 3, the unknown variable is 4), so how do I finish this?

You should be able to solve them but they won't necessarily give you a unique set of solution. You can use a software such as MATLAB to solve it out for you or if you are really interested, you can convert them in a matrix form Ax = B and then do some clever thinking to ensure that 'A' becomes a square matrix. One way is to multiply one or more of your equations by one of the unknowns to get a fourth equation. Once you have 'A' as a square matrix, you can suppress one of the variables and then do determinant(A) = 0 to solve for the variable. This is based on the fact that 'A' has to be singular otherwise x would just be trivial solutions. PS: I know I didn't do a good job at explaining how to solve it. It would require me to write out a lot of equations and consume a lot of time. If you are really interested, you can have a look at one of my papers where I used this method to solve a system of equations. Link to the paper is below and the method is on page 3.

How to solve it for a 3D 5DOF

See the videos in the Robotics 201 series which deals with 3D real world robots.

I'm blind or in 6:40 is mistake? 4 = 9 +1+a (a is sinTheta1+cosTheta1). 4 = 10+a => 4-10 => a => -6 = a So on the right should be 18cosTheta1 + 6sinTheta1 = 6. Please correct me if i'm wrong.

Thank you for commenting! I looked at the working that you provided- you have forgotten to take into account the two terms which are 'Sin^2(theta1) + Cos^2(theta1)'. I used the identity 'Sin^2(theta) + Cos^2(theta) = 1'and so the working that is shown in the video is correct.

Hi Akram, I have actually made a video on writing the MATLAB code for forward kinematics of a robot here: kzread.info/dash/bejne/mYyk1NySaLjJhLg.html This video contains the link to the code as well that you can download. You can modify the code to your liking for different types of robots. For the inverse kinematics, I will be making a video on writing code for it in MATLAB soon. Until then, try modifying the code from above video and see if that works for you. As always, if there is any confusion, write back to me.
