can't spawn mycobot model on gazebo

[graziegrazie]

I tested gazebo.launch on laptop host, not Docker. Mycobot model seems to be spawned, but it is interrupted by someone with signal_shutdown [atexit]. My environment is following.
Ubuntu 20.04
ROS noetic
Any suggestion is helpful for me.

console output

$ roslaunch mycobot_ros gazebo.launch

The reason why gozabo cannot be started may be due to URDF. The model lacks some parameters required by gozabo. I'm not sure if it will be fixed later, maybe gozabo is not needed.
BTW,This package doesn't seem to run directly on neotic.

确实因为URDF，经过加入collision模块和惯性模块，我的gazebo除了第5部分已经可以显示。
而第五部分的dae文件有问题。

[Tiryoh]

I also tried it, but it looks like the collision needs to be changed in the current URDF.
The package, which I made using the URDF released around December 2020, can run Gazebo's myCobot from MoveIt, so I'll share it for your reference.

[tongtybj]

Based on the work of @Tiryoh (https://github.com/Tiryoh/mycobot_ros), I have modified lots of files in this repository and finally I restored the gazebo simulation as explained in #47.

I hope some one help me to test this PR, especially in ros noetic env.

[Tiryoh]

@tongtybj Great!
It looks a little dark in Gazebo. I'll add a review comment later.

@Tiryoh

Thanks for your contribution! I have merged your PR.

For license issue, could you also send a PR to #47 if necessary?

[carlos-411]

Just wanted to see how you were able to get two cobots in the same enviorment.
Maybe this is a very simple question, but am having many issues trying to solve that.

[casiarobot]

You can spawn many times with various namespace or name by 'rosrun gazebo_ros spawn_model '

Help can be got by 'rosrun gazebo_ros spawn_model --help'
