[ERROR] could not find joint_state_publisher
hi, this is my first time here. i'm using indigo and gazebo2.2 in ubuntu14.04 to simulate our robot.
when i was following the tutorils,had a problem with this page.
it says to launch these two,to control the rrbot.
roslaunch rrbot_gazebo rrbot_world.launch
roslaunch rrbot_control rrbot_control.launch
but when i launch roslaunch rrbot_control rrbot_control.launch
this error occcurs.
[ERROR] [1414305408.351300373, 6.335000000]: Could not load class joint_state_controller/JointStateController: Could not find library corresponding to plugin joint_state_controller/JointStateController. Make sure the plugin description XML file has the correct name of the library and that the library actually exists. Warning [Publisher.cc:134] Queue limit reached for topic /gazebo/default/pose/local/info, deleting message. This warning is printed only once.
does anyone solved this problem?
thanks ,
Ryo.
ps
ros_controllers package cause other catkin_make problem, so i tried this
sudo apt-get update
sudo apt-get install ros-indigo-ros-control ros-indigo-ros-controllers
but another error occurs
[ERROR] [1414652580.407543556, 4.281000000]: Exception thrown while initializing controller joint1_position_controller. Could not find resource 'joint1' in 'hardware_interface::EffortJointInterface'. Could not find resource 'joint2' in 'hardware_interface::EffortJointInterface'. I checked
rrbot_control.yaml
andrrbot.xacro
, but of course there was a state about joint1 and joint2.
could you tell me where to check for?
thanks
