Re: [ros-users] pr2_cockpit stack (Teleoperation stack)

Hi,

I'm trying to get the JTTelopController running on our robot. At
first, I checked out the version tagged for cturtle but the
telop_controllers package had a ROS_BUILD_BLACKLIST in it so I moved
on to 'latest' (r39163). From latest I found the launch files
formerly in cartesian_controller_tutorial in telop_microscribe,
launched c_jt.launch (a file that we were using during the workshop),
but then I received errors about something failing to load the
controllers (see below). Have you seen these errors before and
possibly know how to fix them?

Errors from roslaunch:
[ERROR] 1277263944.599523: Failed to load l_cart
[ERROR] 1277263945.605297: Failed to load r_cart

Errors from rosout:
Node: /realtime_loop
Could not load controller 'l_cart' because controller type
'JTTeleopController' does not exist

Node: /realtime_loop
Could not load class JTTeleopController: According to the loaded
plugin descriptions the class JTTeleopController with base class type
pr2_controller_interface::Controller does not exist. Declared types
are CasterCalibrationController CheckoutController
CounterbalanceTestController GripperCalibrationController
HeadPositionController HysteresisController JointCalibrationController
JointLimitCalibrationController MotorJointCalibrationController
