Testing MoveIt2 Python Bindings with real xArm6

[adamanov]

Hello I am trying to use a moveit2 python biding on xarm6, and run a simple example motion_planning_python_api_tutorial.py`

By executing ros2 launch xarm_moveit_config xarm6_moveit_fake.launch.py and then the python example, but getting to bellow error

    panda = MoveItPy(node_name="moveit_py_planning_scene")

I believe the error is related to the configuration of moveit inside _robot_moveit_common.launch.py script. I tried to do it on my own, but unfortunately couldn't understand how can fix it. (sorry I just started with moveit2).

I found a similar issue but related to UR robot Testing MoveIt2 Python Bindings with real UR robot #2014 .

could you please navigate me and help to run the basic motion_planning_python_api_tutorial.py example for moveit-py

All best

Hi @adamanov, could you please share more details of the full error message, and what modifications you have made to example motion_planning_python_api_tutorial.py for adaptation of xArm?

[omukesh]

can some one revert on this ??? regarding pybind ?
