I'm using Process Simulate 14.0.
I want to simulate that Jack folds two of the flaps of carton.
But when I used attach event to attach Jack and lnk of carton, that was my result.
How can I simulate that Jack's arm/hand move to the moving flaps of carton, not the whole body?
Here is my kinematics editor for carton. lnk2 is the left flap. lnk3 is the right one.
Thank you in advance.
Solved! Go to Solution.
Using the "Task Simulation Builder" this is not (yet) possible.
This is something that is likely to be adressed in a future release.
For now - it would need to be modeled using the "old" human operations.
See the attached video showing something similar to what you want to do:
Create the initial grasp posture.
Create two "grip frames", one for each hand.
Depending on how the kinematic device is modeled, this step may not be required.
- In my simple case, it would have worked without these frames.
Attach the grip frames so that they move with the device.
Create a Huamn Event
In the event add one grasp relation for each hand to the grip frames (optionally directly to the object).
You can also specify some "constraints", e.g in this case I lock the torso.
I hope this helps
thank you for your helping, but I can't watch your video.
I tried with a lot of devices to watch this video, but it didn't work and I became an error "Invalid Authorization Respone". It is strange, because I can watch other videos of you.
I read your guide and did what you said, it worked perfectly (took time without video ).
But I have another problem. After the folding Jack's hands still grasp the carton (the kinematics components are colored pink). How can Jack ungrasp the carton?
Hi again Elisha,
Sorry about the video - not sure what the problem is
I'll try uploading again.
Happy to hear you were able to get it working following just the description!
In order to release the flap, create another human event.
This time the Grasp should be set to "Release":
Hi,Elisha & Pelle,
Very interesting topic. I am using PS14 Human, I run into almost the same question, I am working on a manipulator which will help load the part like a tire to the car. Manipulator kenimatics joints have been set up.
I am trying to use a device operation for the manipulator to move the manipulator into different location, Human model suppose to walk and grab the handle of the manipulator. but when the manipulator move, Human model didnt follow as what it should be? Grasp operation is the operation before the device move (manipulator).
any help will be appreciated.
First - I see that somehow the video I tried uploading for Elisha somehow doesn't work.
Please take a look if you can access the below ok:
The key to get it working is adding a Human Event, dictating that the human hand(s) should follow the moving device. One other important point to make, this event need to have the hand(s) following a moving link of the device, not the device itself. If the human still does not move as expected, you may need to create Frames on the handles of the device, attach the frames to the links of the device. Then have the human follow these frames instead of the links. If you still don't get it working - can you share a video/data?
Hi again Parkan,
I wanted to share one more hint.
The human can walk while following a moving object.
The human however cannot walk well with his Torso Bent Forward.
That is, if possible try to ensure that the grasping of the object is performed with a straight back.
That will make it easier for the human to preserve the grip of the object while walking.
