Hello,
I am trying to spawn the differential drive robot in the gazebo and I'm getting these errors.
[ERROR] [1548165426.418484914, 0.290000000]: Robot descripion couldn't be retrieved from param server.
[ERROR] [1548165426.418530005, 0.290000000]: Failed to initialize the controller
[ERROR] [1548165426.418554743, 0.290000000]: Initializing controller 'omronld_velocity_controller' failed
[ERROR] [1548165427.420084, 1.258000]: Failed to load omronld_velocity_controller
I have interfaced robots wheels transmission with VelocityJointInterface. I have written the gazebo_ros_control plugin for the gazebo, however, I did not include differential_drive_controller plugin instead I use controller manager to control the robot. If I run my robot with a robot_description name for URDF parameter then everything works fine but if change the robot_description with omronld_description I get above errors. Also, I have remapped the robot_description to omronld_description during the node robot_state_publisher.
More info: omronld_velocity_controller is of the type "diff_drive_controller/DiffDriveController"
Kindly help me with this.
Thank you.
