The weight on position constraint for link is near zero. Setting to 1.0.
Hi,
While trying to move a robotic manipulator to a new pose (using MoveIt!), in order to move to the Next Best View of the manipulator's workspace using the YAK package, I repeatedly get this warning which states that
The weight on position constraint for link 'camera_depth_optical_frame' is near zero. Setting to 1.0.
Is this the reason why I am getting the following error?
Position constraint violated on link 'camera_depth_optical_frame'. Desired: -0.300000, -0.300000, 0.800000, current: -0.187025, 0.287808, 0.549807
