Gazebo arm controller failing

[MatthewKimball]

Hi,

I am trying to run the simulated shadow robot arm in gazebo, it manages to generate the model but it fails to implement the joint controllers. Using the command 'roslaunch sr_hand gazebo_arm.launch' to start the simulated model, I am recieving the following errors during the initialisation process.

[ERROR] [1459100091.268040115, 5.376000000]: No type element found in transmission 'trunk_rotation_transmission'. [ERROR] [1459100091.268198367, 5.376000000]: No type element found in transmission 'shoulder_rotation_transmission'. [ERROR] [1459100091.268311125, 5.376000000]: No type element found in transmission 'elbow_abduction_transmission'. [ERROR] [1459100091.268377496, 5.376000000]: No type element found in transmission 'forearm_rotation_transmission'.

Following these errors, additional errors a displayed indicating the failure to initialise the respective position controllers.

Any suggestions as to where it is going wrong would be greatly appreciated.

The simulated shadow robot arm is not being maintained currently.

Please use the simulated UR10 arm + shadow hand instead. To use it please install our packages from source by running the one liner script as explained in:

https://github.com/shadow-robot/sr-ros-interface/blob/indigo-devel/INSTALL.md

And then run the launchfile as in "Shadow hand with UR10 arm":

Partially fixed here https://github.com/shadow-robot/sr_common/pull/18 for some reason the trajectory controller does not move the arm when started with arm_and_hand.launch.

could be a conflict of resource access by the two plugins (standard and shadow version). The shadow version of the gazebo_ros_control seem to handle the hand only which explains why the arm did not move.
