Hello,
There seems to be a problem with an example in the documentation.
The example is under here:
https://robodk.com/doc/en/PythonAPI/robo...em.SolveFK

(1) it needs to import robomath
(2) the variables need some values... like x_move=300 y_move=0 z_move=0
(3) you can't use continue outside of a loop

So there is no hope of this example actually working.  But if you fix those problems there appears to be a larger issue with the choice of comparing configurations.  The scripts are in the attached file for your enjoyment.

The error looks like this:

Code:

Traceback (most recent call last):
  File "C:\Users\henry\AppData\Local\Temp\Example_from_documentation.py", line 30, in <module>
    if robot_config[0] != new_robot_config[0] or robot_config[1] != new_robot_config[1] or robot_config[2] != new_robot_config[2]:

The returned value from JointsConfig is a Mat object (of size 4x1), not a list object. You can convert it to a 4D array by calling list on the Mat object. Example:

Code:

robot_config = robot.JointsConfig(robot_joints).list()
...
new_robot_config = robot.JointsConfig(new_robot_joints).list()

RoboDK may return a list object directly in future versions.
