SOLUTION: This object named 'T' is not a normal matrix so normal indexing wont work. 'T' is a special class of object called 'SE3' and Matlab thinks it's a scalar 1x1 (thats why the error says you can't exceed 1, cause it's a 1x1 object). The SE3 class has a method that can extract the translation part you need into a 1x3. The method is 'tform2trvec(T.T)', where T the SE3 object. From there you can use normal referencing on that 1x3.
Thank you for the video it inspire me to learn more about it. Anyway do you have any book reference / website to learn robotic especially in matlab and the analysis of robotic arm. Thanks

My robot runs forward kinematics but doesn't display the X,Y,Z values. An error is brought up with the use of 'floor' in handles.pos_X.String = num2str(floor(T(1),4)); is there any alternative name to use?
Don't know if you still need this but here you are. The object structure has probably changed since the video has been posted, you can access to the positions through the subfield t like T.t(i) with i=1,2,3. So it should look like app.Pos_XEditField.Value = num2str(floor(T.t(1))); app.Pos_YEditField.Value = num2str(floor(T.t(2))); app.Pos_ZEditField.Value = num2str(floor(T.t(3))); I'm using the newer Matlab GUI editor, if you are still using GUIDE I think it should be something like handles.pos_X.String = num2str(floor(T.t(1)); handles.pos_Y.String = num2str(floor(T.t(2)); handles.pos_Z.String = num2str(floor(T.t(3));

Hi! So I just solved this problem with a friends help. If you press T on 'workspace', you will get that T is made from 4 arrays (t, n, o, a) to form a structured element which we see is T. In the command window, typing T gives you a 4x4 matrix. Yet when you type size(T), it will return 1 1. Thus. in order to retrieve the X, Y and Z coordinates from T, you must specify T.t(1,1), T.t(2,1) and T.t(3,1) respectively.

Hi Chris, I solved it, but I am sorry that I have some project nowadays. Therefore, I will suggest a method and give an information about what I remember. Would you try to replace T(1,4) with T(4).

Hey I was facing the same issue right now. So I solved it like this: Notice T = Robot.fkine([Th_1 Th_2 Th_3]); gives an SE3 object. If you call T in command line, it will display a 4x4 Matrix. Try calling individual elements from this matrix conventionally, you'll notice you can't. To overcome this problem, extract the 4th column of T by using code T.transl Then instead of calling T(1,4), call the individual elements from the new vector obtained. Example code: T = Robot.fkine([Th_1 Th_2 Th_3]); T_tr = T.transl; handles.Pos_X.String = num2str(floor(T_tr(1))); handles.Pos_Y.String = num2str(floor(T_tr(2))); handles.Pos_Z.String = num2str(floor(T_tr(3)));

It's the links of your robot. For exampel, most industrial robots consist of 6 links with varying length. A tip is to write "help Link" in matlab, it will then show you everything you need to know about the command.

Hi Maciej, use Robot.ikine(T, [0 0 0], 'mask', [1 1 1 0 0 0])*180/pi; Option is called 'mask' , M where M is a 6X1 vector The mask states which Degree of freedom can be ignored. The vector [1 1 1 0 0 0] means x y z is 1 i.e we need them, and rotation x y z is 0 i.e not needed or can be ignored. which corresponds to this 3 DOF robot in Ahmed's example.

did you get this fixed ?
SOLUTION:
This object named 'T' is not a normal matrix so normal indexing wont work. 'T' is a special class of object called 'SE3' and Matlab thinks it's a scalar 1x1 (thats why the error says you can't exceed 1, cause it's a 1x1 object). The SE3 class has a method that can extract the translation part you need into a 1x3. The method is 'tform2trvec(T.T)', where T the SE3 object. From there you can use normal referencing on that 1x3.
I suggest the following code;
T=Robot.fkine([Th_1 Th_2 Th_3 ]).T;

Hey I was facing the same issue right now. So I solved it like this:
Notice T = Robot.fkine([Th_1 Th_2 Th_3]); gives an SE3 object. If you call T in command line, it will display a 4x4 Matrix. Try calling individual elements from this matrix conventionally, you'll notice you can't.
To overcome this problem, extract the 4th column of T by using code T.transl
Then instead of calling T(1,4), call the individual elements from the new vector obtained.
Example code:
T = Robot.fkine([Th_1 Th_2 Th_3]);
T_tr = T.transl;
handles.Pos_X.String = num2str(floor(T_tr(1)));
handles.Pos_Y.String = num2str(floor(T_tr(2)));
handles.Pos_Z.String = num2str(floor(T_tr(3)));

There's a problem in my inverse part, there's no value that shows after i run the inverse kinematics but the forward kinematics really works fine
same problem plz help !!!
The same problem with most of the comment is happening to me also.
the matlab can't figure out what is link , matlab gives an error as the variable is not defined
so the question is how do I define Link ? or what should I say Link is equal to ???

Plz help me out with this problem
Hi there - I have the same problem. Maybe there is someone who knows the answer.
WHAT IS [Link]
It's the links of your robot. For exampel, most industrial robots consist of 6 links with varying length. A tip is to write "help Link" in matlab, it will then show you everything you need to know about the command.

Bass heavy track.
i used same program but there is some issue regrading line 95 in guide.
Hi! So I just solved this problem with a friends help. If you press T on 'workspace', you will get that T is made from 4 arrays (t, n, o, a) to form a structured element which we see is T.
In the command window, typing T gives you a 4x4 matrix. Yet when you type size(T), it will return 1 1. Thus. in order to retrieve the X, Y and Z coordinates from T, you must specify T.t(1,1), T.t(2,1) and T.t(3,1) respectively.
Number of robot DOF must be >= the same number of 1s in the mask matrix Thats the error im geting from using
J = Robot.ikine(T, [0,0,0], [1 1 1 0 0 0]) *180/pi; Any tips?
Btw. In matlab 2016 it fix problem with fkiine
handles.Pos_X.String = num2str(floor(T.t(1)));
handles.Pos_Y.String = num2str(floor(T.t(2)));
handles.Pos_Z.String = num2str(floor(T.t(3)));
Hi Maciej, use Robot.ikine(T, [0 0 0], 'mask', [1 1 1 0 0 0])*180/pi;
Option is called 'mask' , M where M is a 6X1 vector
The mask states which Degree of freedom can be ignored. The vector [1 1 1 0 0 0] means x y z is 1 i.e we need them, and rotation x y z is 0 i.e not needed or can be ignored. which corresponds to this 3 DOF robot in Ahmed's example.
