How to actuate the ball joint in Gazebo?
I want to actuate the ball joint in Gazebo for my academic project. The ball joint is supported only in sdf format, and the gazebo_ros_control package which is used for actuating the joints is used with the URDF description of robot. So, how should proceed to solve this issue? PS: I cannot use set_link_state topic as I want to have arbitrary movement of the joint. Currently i am using a single sdf file describing the simulation world including robot model. If I include the plugin tag in the sdf file, the simulations does not run and I get following output in terminal.
