[ros-users] values are zero in joint.h

[Stuart Glaser]

Hi Andreas,

Could you double check that no error messages are showing up in
rosout/rosconsole?  It's possible that the transmission didn't come up
correctly.

Let's also check if the actuator is changing.  Echo the
mechanism_statistics topic, and check the values for the actuator that
you're connecting too (joint_p-a1_motor).

Could you also re-post the configuration for your transmission with
the corrected joint/actuator values?
