Initializing controller failed (RRBOT tutorial)

Question

Hi folks.

I'm working on the tutorial of Gazebo 1.9 with rrbot and currently facing the following error messages.

From the controller start launch file:

[INFO] [WallTime: 1375388998.774908] [0.000000] Loading controller: joint1_position_controller
[ERROR] [WallTime: 1375389000.170747] [28.387000] Failed to load joint1_position_controller
[INFO] [WallTime: 1375389000.171134] [28.387000] Loading controller: joint2_position_controller
[ERROR] [WallTime: 1375389001.195123] [29.373000] Failed to load joint2_position_controller

And from the Gazebo launch file:

[ERROR] [1375388999.165926429, 27.406000000]: Exception thrown while initializing controller joint1_position_controller.
Could not find resource 'joint1' in 'hardware_interface::EffortJointInterface'.
[ERROR] [1375388999.166263170, 27.406000000]: Initializing controller 'joint1_position_controller' failed
[ERROR] [1375389000.189563304, 28.401000000]: Exception thrown while initializing controller joint2_position_controller.

[ERROR] [1375389000.190056911, 28.404000000]: Initializing controller 'joint2_position_controller' failed

I have followed the tutorial step by step and used the gazebo_ros_demos package.

Thank for the help.

Answer 1

Well, I changed a lot of things, so I'm not sure of what was the root cause.

What I did:

• install ros-hydro-desktop-full
• install gazebo, which has removed the previous package, but only the meta package (fixed in the meantime)
• install ros_control from the source (did not manage to make the deb version work)
• install ros_controller, control_toolbox and real_time (since again the package were missing or inconsistent in the debs)

And this is now working fine.

I think the debians were just out of date, I just released a update that should be in public with the next Hydro public sync
