2019-05-10 04:19:22 -0600 | marked best answer | Still runaway simulations in gazebo Hello List, UPDATED YET AGAIN: See 3rd update below! I am having difficulties in getting stable behaviour with my simulated rowing boat.
The model can be found on my github page in the A simplified version can be found in the testing directory
Please see Sometimes there is an error message like: The model is What does help is reducing the Hopefully someone can help, as I am really stuck here. UPDATE: Enforcing more limits as in seems to be completely ignored the model and gazebo crashes just the same! 2nd UPDATE: Getting a bit despondent here. I can get it a bit better by increasing The instability maybe comes from two or more joints connected directly together as in an elbow or shoulder using e.g. So with no change in the origin. If you pull the Rowing repository and then do you will see the simulated rower in gazebo. Starting the simulation (and the control via ros_control) will show the crashing fairly quickly. The following shows that a simplified model does work ok. 3rd UPDATE After some help from gazebo/issues I now have a better simple example that still crashes! Please see this folder on my github page. The video shows the usual form of crashing. Sometimes gazebo crashes entirely with the error mentioned above. Simplifying it further makes is stable most of the time. For example removing the fixed_joint ... (more) |
