Please note: ABB RobotStudio interface is only available in realvirtual.io Professional.
is a powerful solution from ABB for offline programming and simulation of ABB robots.
With the RobotStudio interface, the virtual ABB robot controller can be connected to realvirtual.io / Unity. The current axis positions as well as signals are cyclically exchanged between RobotStudio and realvirtual.io.
You need to prepare a robot with the usual realvirtual.io kinematics. Each axis of the robot must be assigned a drive and a Drive_FollowPosition script. It is important that all drives are defined at the correct rotation position and that the positive direction of the drive is the same as for the real robot.
The interface between realvirtual.io and RobotStudio uses the Simit shared memory interface that comes with RobotStudio. You need to add it in the station logic.
It is important that the SharedMemoryName matches the SharedMemoryName property of the ABBRobotStudioInterface in Unity.
In SharedMemoryName, enter the same name that is used in RobotStudio.
If you insert the ABB RoboStudio interface into your scene as a prefab or via the realvirtual.io menu, you will already get some sample signals imported. You may need to adapt these to your robot cell.
You have to define the signals manually in realvirtual.io, because ABB RoboStudio connects to the shared memory as a client and transfers the data depending on the listed signalm in the shared memory.
There are naming convention for naming robot joints and input and output signals (e.g. *Joint[1]+ or *Robot[IRB7600_400_255][DigitalIO]StartRobot).
For more information on naming, see the ABB RoboStudio Help.
It is also very important that the input and output signals are mapped to identical bits on both sides by using the device mapping in ABB RoboStudio. The realvirtual.io signals are arranged in the memory in the order in which they are visible in Unity Inspector. You can check the memory location (in shared memory) by checking the signal comment in Unity Play mode.
It may be necessary to add some empty dummy signals so that the position of the bits of the data remains identical. You also need to make sure that input and output bits are not mixed in one byte. Here is the signal configuration for the example shown above:
