In the published version of the above paper, the URL for a video of the experiment was missing from the second paragraph of section 6.1 Experimental results.
The paragraph should read as follows:
In this experiment, a target position is given to the left arm of the robot. The path for the arm is then computed using the proposed algorithm. The resulting path can be seen in Fig. 14. For a recorded demonstration of the experiment see YouTube video at https://www.youtube.com/watch?v=gkArSOl3m9Y.
