I need to get the target joints of movement without moving the robot on simulation.

我可以使用finction SolveIKthis:
new_robot_joints = robot.SolveIK(joints, tool=tool)
print("--->",new_robot_joints.tolist())

But when I try to get the joints with a tool I get error:
toolWeld = RDK.Item('KH-TOURCH')
print("XXX-->",toolWeld.Pose())
new_robot_joints = robot.SolveIK(joints, tool=tool)
print("--->",new_robot_joints.tolist())

This is the error:
Traceback (most recent call last):
File "D:\work\Design\Welding-Robot\Modular-Structures\kehui_simulation.py", line 468, in
new_robot_joints = robot.SolveIK(pose=joints, tool=tool)
File "C:\RoboDK\Python\robolink\robolink.py", line 4606, in SolveIK
pose = pose*invH(tool)
File "C:\RoboDK\Python\robolink\robodk.py", line 353, in invH
return matrix.invH()
AttributeError: 'Item' object has no attribute 'invH'


Question:
1/ Is there other a way to get the joints with tool?
2/ why I get this error although the tool is corret

The tool you provide to the SolveIK function should be a pose (a 4x4 matrix as an object of type Mat).

Example:

Code:

new_robot_joints = robot.SolveIK(pose=robot.Pose(), joints=robot.Joints(), tool=robot.PoseTool(), frame=frame.PoseFrame())

Thanks, it is working perfect.
