I am in the process of making a chess program as show in image. I am using python to move the robot in the 64 squares of a chess board. I am not sure how I can do the attach function in pyton. I am able to do it in the RovboDK environment.

There are several ways to attach an object to the robot's flange (or gripper). You can use the simulation event instruction in a program created using the UI. This link shows an example to add new instructions to a program using the API:

I think there are several ways to attach An object to the robot's flange (or gripper): its better you would use the simulation event in your code,  or you change the parent an object is attached to...
this link (https://robodk.com/doc/en/PythonAPI/exam...structions) with an example help you solve this problem.

You can use the API call setParentStatic to attach one object to another one while maintaining the absolute position of the child object.

Example:

Code:

object1.setParentStatic(object_attach_to)
