Hey man, I have found your video very helpful, I just have one question, thhe program runs as normal and it shows the plot for my robot but I dont get the matrix on the command window, do you know why it may be? Thank you!
Hello, when I use Link function, I have an error which is below written. Could you please help me that how to solve the problem? Undefined function 'Link' for input arguments of type 'double'. Error in Rotobit_Arm_3D (line 6) L(1) = Link([0 675 350 -pi/2],'standard');
When I use which Link, it addresses the Link.m file. Link.m file has below codes. function op = Link(op,fact_i,ptr) % op = Link(op,fact_i,ptr) % eval_fill required afterwards. % Copyright 2000-2004 The MathWorks, Inc. and Ford Global Technologies, Inc. op.linkptrlist(fact_i) = ptr; %op.factor_type(fact_i) = 2; if op.factor_type(fact_i)==1 %if op.created_flag(fact_i)==0 & isvalid(op.ptrlist(fact_i)) % Store original data as a hidden column if isempty(op.data) % Ensure that empty oppoints can be handled storedata = []; else storedata = op.data(:,fact_i); end op = addfactor(op,op.ptrlist(fact_i),storedata); if ~isvalid(op.ptrlist(fact_i)) % Obscure case of linking to an unassigned input % Example: Fill a trade off table with cst and % try to link to that cst % This change should avoid a subsequent error in findName op.orig_name(end) = op.orig_name(fact_i); end op.factor_type(end) = 3; % hidden op.factor_type(fact_i) = 1; %op.grid_flag(end) = op.grid_flag(fact_i); end % Need to do this - but do it outside (eg when OK pressed) % Slows things down otherwise %op = eval_fill(op);
Hi! I have a question, I want to make a DH model of an ABB IRB 460, a pick-and-place robot. The last one is like a passive joint. Could you please help me? Btw your videos are awesome.
@@amazingengineering3207 Thinks for your help. So the last part is like a tray, its X axies are alway perpendicular to the XY plane related to the ground. Can I just add the value to the end of the first joint? Like have the robot's 3 part with DH parameters, then just add the rest. The point is that I want to make a work envelope, but without the last part the results are not valid.
This was a life save.. Thanks a lot!
Thank you so much!

Hi. If you mean the D&H parameters matrix, if you wanna plot it you have to write the serialink command without using ";"

Which is the message?
Are you sure you have installed the toolbox?
@@amazingengineering3207 No, I have not done it. How can I instal the toolbox?

I don't remember the link but you can search for "Matlab robotics toolbox Peter Corke"

If this passive joint is part of the end effector you could represent only the first part of the robot

Niceee, thank you
Can you share codes?
