This Seeking Tech guide will explain how you can take a group photo with any combination of VIP bots.
Use the following video as a reference:
For the first step, you need to head over to any of the four outer locations at the Crash Site hub.
Afterwards, press Triangle to call all the bots over to the location.
You then need to press Triangle again to make them stand in place.
You can then push any bots aside to isolate them from the rest of the group. You can also punch them to move them into higher ground.
Once you get your crew together, you should be able to take your desired group photo.
