2021-02-11 08:43:13 -0500 | marked best answer | Properly making soft joints to world in Gazebo 9 + ROS Melodic I'm trying to interact a position-controlled robot with "fixed" obstacles in its environment. In this case, they're a couple of floating spheres, "magically" fixed in space. I'm using default With If I add some global constraint force mixing with What I'd like to do is attach the floating spheres to the world frame using spring-dampers that are much softer than the robot joints, so that they easily slide out of the way if the robot collides without pulling the robot joints apart visibly. I'm having a very hard time finding a correct and complete description on how to do this, partially because any suggestions are scattered across many years of SDF file format changes, unanswered ROS Answers and Gazebo Answers questions, and so on. I have successfully held the spheres in place with fixed joints so they move a little with relaxed constraints. After a long time experimenting (because of lack of a complete example) I figured out I could put those joints in a nested Now I'd like to soften the joints that hold the spheres in place. So I'm trying to set different I still can't find a documentation source that's any more useful than http://sdformat.org/spec?elem=joint&v..., but that just kind of tells me which tags I might try, not how they fit together. The image was captured using these settings for the red sphere: The spheres had mass properties like solid plastic when I started. I tried making them thin, extremely light spherical shells, which made it shakier but roughly similar in relative sphere and robot displacements. At the world level (which contains the red and blue sphere models, ground plane, and sun), I have this: (more) |
