Grasp Wizard 2 (Professional)

Extensions and Python Add-ons
1

Hello all,

I have been using the original Grasp Action Wizard (Professional), and over time, I added some additional functionalities.

As with the original addon, you can add grasping and releasing functionalities to any component.
This updated grasp wizard can trigger the grasping signal automatically based on collisions and servo motions. The grasping logic has also been updated for new functionalities like process modeling assemblies.

Usage

Connect and send a True signal to GraspSignal for grasping and a False for releasing. Check TCPFrameLocation and DetectionVolumeSize if components are not picked up. Grasped components are attached (and following) the Node/Link given when applying the wizard.
Additionally, you can select a servo joint that will trigger the GraspSignal automatically when the servo moves or changes direction past the threshold.

13.06.24 Update: Small improvements and bug fixes.

Installation
Requires access to Modeling tab (Professional or Premium license)
Download the addon package:
GraspWizard2.zip (16.5 KB)

Like usual: Unzip the file to your “My Commands” and re-launch. E.g C:\Users%username%\Documents\Visual Components\4.8\My Commands
or
C:\Users%username%\Documents\Visual Components\4.9\My Commands\Python 2\

What results do you get If you enable the message prints? And have you tried changing the gravity direction value?

Hello Esta,
A few days ago i installed the grasp Wizard 2. after assinging the true signal it did work.
After saving the program and reopening it, i get two messages and can’t get the grasp function to work again.

Looks like you have renamed the signal name. You can modify the Grasp script around lines 680 to use the new behavior names and then it should work again.

Instead of detection_node.Name, replace these lines with the exact name of the behaviours you want to use.

Hello everyone,
I’ve been using the default Grab Wizard so far.
The expert version is more utilized, so I’m going to try using it as the appropriate Add-on.
Unlike the Grab Wizard I used before, many function have been added, so are there any manuals or instructions on what each function means and how to use it?
