Finally saw this the other night, and noticed that the titular character's name is definitely a shoutout to Capek's play.
The movie itself is basically a "heartwarming family film", and I enjoyed it well enough, but had very big plot logic/world logic problems with one sequence which became even more pronounced at the denouement. -- columbiaclosings.com What's not in Columbia anymore..
Shoutout to Capek in "The Wild Robot"
