How to save dynamic picture about the trajectory of the end-effector ?

[黄俊豪]

qs=[0 0 0 0 0 0];

qr=[0 6.6 -6.6 0 0 0];

q=jtraj(qs, qr, 50);

puma560.plot(q, 'trail', 'r--')

The figure is dynamic and i want to save it as .avi or .gif .   Thanks a lot !

Hi,

checkout

>> doc VideoWriter

please note this is not a RTB function. So any further questions regarding VideoWriter don't belong in this about this discussion group. For this I would suggest to google on: matlab create avi or something similar.

Hi,

after I posted the message below I saw a .movie property in the SerialLink object. After checking how to use this, I don't see any use of this property at the moment other than throwing an error @ line 142 of animate.m

As specified in SerialLink.m the movie parameter should be filename (like 'test.mp4' ) or a folder in which the individual movie frames will be saved. However, @line 142 of animate, movie is expected to be a class which contains a method add(). Though I was not able to find any code related to this.

So it is probably an old part of code or a part of code which is still under construction. For now I suggest to manually save the video using the VideoWriter which I mentioned before.

will do the animation and save it as a movie.  I've just noticed that a vital helper class is missing in the distro, please install this on your path.

Hi, Mr.Corke！

Sorry to bother you again. Could you upload the Animate.m again? I can't download it.

I can download it OK.  Note sure I would do anything different if I uploaded again.  Try clicking on the View button and then cut and paste the text into a new file.
