Hi, I load motoros 1.8v of @ted-miller, I have executed roslaunch successfully. But now have other problem when launch demo (without joint state publisher) with the arm left, already that the joints is missing.
[ERROR] [1527541542.427483218]: State monitor received invalid joint state (number of joint names does not match number of positions)
[ERROR] [1527541542.559572523]: Robot state publisher received an invalid joint state vector
