some wrong with easy_handeye，how to use rasy_handeye with five-axis robotic arm?

[Galers-LEE]

Dear sir, I have some questions to ask you, I hope you can help me answer!
I have a 5-axis robotic arm, using easy_handeye to do hand-eye calibration, this interface can't check starting pose and next terminal error says it can't recognize the position, has anyone seen this situation before?
Running aruco_ros calibration alone has results, can recognize the position, but with the addition of the robotic arm it does not work.
And the tf:camera_color_optical _frame of binocular camera is flashing, the four tf:camera_color_frame, camera_depth_frame, camera_depth_optical_frame, camera_link can't be connected correctly.
I have changed the name of the robot arm model in the calibrate.launch file to the name of my own robot arm, what other improvements do I need to make? If you have time to reply me, I will be glad to hear from you, have a nice life.

Hi @Galers-LEE,

to the best of my knowledge, this package will not work with a 5 DoF arm. It may, if you still can rotate the end effector about all 3 Cartesian axes.

Please check the scientific literature about the problem. I would welcome a PR adding other calibration methods that work better in your case.
