Confusion about IKFast installation

[bjutlss]

Description

I tried to configure the IKFast plugin for my 5D robotic arm in the ros-noetic version and installed it according to the IKFast Kinematics Solver, completing all the steps, including installing the docker image personalrobotics/ros-openrave. But when running the command roslaunch "$MYROBOT_NAME"_moveit_config demo.launch to verify the feasibility, I can't drag the interactive ball at the end.
I'm confused about this, is it because I didn't generate a container based on the image that caused ikfast to be unable to call openrave? Or something else, I hope I can get an answer.

Your environment

• ROS Distro: Noetic
• OS Version: e.g. Ubuntu 20.04
• Source or Binary build? Source

Steps to reproduce

I followed the instructions step by step to install.

Thanks for reporting an issue. Because we're a volunteer community, providing a pull request with suggested changes is always welcomed.

Please provide the log of the generator script auto_create_ikfast_moveit_plugin.sh as well as a link to your generated *_move_config files. From the output of the MoveIt itself, one cannot guess what went wrong during the generation.

Sorry for not replying in time. I cannot find the log of the generator script auto_create_ikfast_moveit_plugin.sh,Can you give me some tips on logs? For example the exact path.
Thanks.

[rhaschke]

I'm afraid there is no log file of this, but you need to repeat the generation process.

In fact, I have followed the instructions and installed it no less than 5 times, for which I have tried to configure 6D ikfast for ur5 and it is working fine. But configuring ikfast with TranslationDirection5Dd for my own 5-DOF robot arm does not work properly.

I'm sorry for that, but without the log, we cannot help.

Where should the log file be generated? Is it a normal phenomenon to have no log files? I tried searching the entire workspace for a file like ikfast.log, but no luck. Can you tell me the name of the log file?

[rhaschke]

As I said, there is no log file of the output. You need to pipe the cmdline output of the generator into a file on your own.

I might see what you mean, I will try to generate my log file. Thanks for your reply!
I should save the cmdline in a file when I run the code below, right?
rosrun moveit_kinematics auto_create_ikfast_moveit_plugin.sh --iktype Transform6D /tmp/$MYROBOT_NAME.urdf <planning_group_name> <base_link> <eef_link>
