The problem is: while jogging in y axis, the end of arm not moves as expected. Remaining axis are working fine. Could it be a bad setting in the robot configuration?, am I missing something while using the jogging feature?</span></font></div><div><font face="Arial, Verdana"><span style="font-size: 13.3333330154419px; line-height: normal;"><br></span></font></div><div><font face="Arial, Verdana"><span style="font-size: 13.3333330154419px; line-height: normal;">The quaternion values configured in the Motion topic are: q1= 1, q2= 0, q3= 0, q4= 0</span></font></div><div><font face="Arial, Verdana"><span style="font-size: 13.3333330154419px; line-height: normal;">Tool : tool0</span></font></div><div><font face="Arial, Verdana"><span style="font-size: 13.3333330154419px; line-height: normal;">workobj: wobj0</span></font></div><div><font face="Arial, Verdana"><span style="font-size: 13.3333330154419px; line-height: normal;">co-ordination system : tried in base & world.</span></font></div><div><font face="Arial, Verdana"><span style="font-size: 13.3333330154419px; line-height: normal;">Gravity beta value : 3.1415</span></font></div><div><font face="Arial, Verdana"><span style="font-size: 13.3333330154419px; line-height: normal;">pls,find attachment for videos.   help</span></font></div>
