RAC Droid designs for Ad Astra 2019. I haven't seen the movie yet so I'm not sure if these made it in!
These are 3d printing droids that construct the tethers in the film.
Thanks to Step Zavala for art direction! Copyright ILM
An ambush keyframe showing a corrupted RAC droid attacking the astronauts
A keyframe showing the RAC droid building a space tether. there would be many of these droids constructing at one time
Alternate design, more anthropomorphic
Another alternate version of the ambush keyframe with a droid with less humanity, less relatable as a 'being'
