Strange behaviour when loading robot #184

Open MatteoPerotto opened 2 years ago

MatteoPerotto commented 2 years ago

Hi all! I started from the URDF file of a 5 fingered hand and obtained the .xml description using urdf2graspit tool. I put here the output files of the generated robot, which is loaded in a wrong way (as in figure below).

MicrosoftTeams-image (4)

After trying to investigate if the error was generated during the "translation" part, I decided to change by hand the values of the <translation> tag in <transform> tag of the <chain>, with the goal of palcing the root of the chain in the right position on the palm. For some reasons that I don't know, there is no effect on the robot. When I load it, the configuration remains the same.

I have also tried to put two values instead of three in the tag, an error is raised. This means the file is read and the robot is imported, but a change in numeric values of <translation> tag has no effect in the robot.

Do you have any idea about the reason of this behavior?

Thanks in advance.
