Astro has to locate the charger and back in with reasonable precision. I wondered about other locations.

I sent Astro from the charger to a spot that I named "speaker," then marked the arrival location with painter's tape.

Next, from three random locations I sent Astro to "speaker."

These arrivals are in the vicinity, but not too predictable.  Next, I placed obstacles near (but not obstructing) the arrival zone.

This (very limited) test seems to indicate that a reliable landing spot can be defined for auxiliary devices to operate on Astro's load bay.
