MoveL has a problem with PoseTool()??-tharisata-02-10-2021
Hi,
In my Python API:
I've created a Tool like so:
self.robot=self.RDK.Item('KUKA KR 60-3', ITEM_TYPE_ROBOT)
tool_array=Mat([[1.000,0.000,0.000,0.000],
[0.000,1.000,0.000,0.000],
[-0.000,0.000,1.000,167.000],
[0.000,0.000,0.000,1.000]])
self.robot.setPoseTool(tool_array)
Then I created a target in RoboDK simulation called 'Calib_Area'.
Interestingly, calling:
self.robot.MoveJ(self.calib_area)
self.robot.MoveL(self.calib_area)
DOES TWO DIFFERENT THINGS!!
MoveJ moves the specified TCP (PoseTool()) to the calib_area target. BUT MoveL, moves the Robot Flange to the target instead?!
Anyone know why this is? I'm very curious.

Hi Tharisata,
I was intrigued, so I tested it out with a station I created and the code you provide with just a mini modification and the behavior was as expected. Both MoveJ and MoveL reached the Calib_Area target.
Here's the station.

Hi Jeremy,
Thank you for testing it out. It works fine in the simulation but not when connected to the real robot and doing online programming.
I can take a video for you if that would help?
RE: MoveL has a problem with PoseTool()??-Jeremy-02-15-2021
Hi Tharisata,
The fact that you are using it on the driver is quite a huge difference and you should have mentioned that from the get-go. I couldn't really just guest it.
MoveJs and MoveLs are fundamentally different from a driver perspective.
MoveJ will send the joint values while MoveL will send the cartesian values.
We then need to figure out if the wrong values come from RDK, the driver, or the setup on the controller side.
I'll ask you to do 2 things.
1 - Make sure this option isn't activated.
2 -Before connection to the robot, press "CTRL"+"ALT"+"SHIFT"+"G" to enter developer mode.
Try connecting to the robot and running the program. Then send the content of the Log file ("Connection window"->"Show Log").

Hi Jeremy,
You're right. I should have told you first! Thank you for pointing that out.
1) Done as you requested, that option was never selected.
2) Entered Developer Mode:

This was the code:
self.robot.MoveJ(self.home)
self.robot.MoveJ(self.calib_area)
self.robot.MoveL(self.calib_area)
self.robot.MoveJ(self.calib_area)
我将发布一个视频在这向你们展示's not moving to the same point. Thanks

RE: MoveL has a problem with PoseTool()??-Jeremy-02-18-2021
Hi Tharisata,
First I don't see any "SETTOOL" in the log file.
You should have something like that:
Otherwise, the robot will use TOOL[0] from the robot controller, which is most likely the flange.
