Hi ROS developers, I have a question. I made a Delta robot (Parallel robot) for my school project. Because delta is a closed kinematics chain I made an SDF model to simulate in Gazebo. I can spawn SDF in the Gazebo but I can not find a way to simulate my ROS code on the SDF model. I tried to use "gazebo" tags to add the SDF part in URDF but that is not working, I know for converting SDF to URDF, but I can't use that because of a closed loop. My question is, how to simulate SDF in the Gazebo? If you know something I can use, please help!
