Here's my attempt: However, it leads to this result: Now, I'm pretty sure I didn't pass the urdf file the correct way. So if you guys can give me a full example on how to do it in Python, that would be awesome! |

2019-11-06 01:42:13 -0500 | marked best answer | [Gazebo 9] Could not find parameter robot_description on parameter server Hi, I know this question is asked a couple of times before, but I just couldn't find the right answer for me. So I'm trying to launch my URDF model with gazebo plug in and use ros_control package to control the movement. But as soon as rover_control.launch run, the error (Could not find parameter robot_description on parameter server) appears. Now, I think this happens because I messed up something in my launch file, my yaml and my urdf. So I will quote three of them here. Thank you for your patient, this is my first week of learning ros. Control launch file: YAML file: And the URDF file: (more) |
