Teens in the Universe (Russian: Отроки во Вселенной, romanized: Otroki vo vselennoy) is a 1974 Soviet science fiction film directed by Richard Viktorov based on a script by Isai Kuznetsov and Avenir Zak about teenage space travelers.

The crewmembers of ZARYa starship supposed to mature during 27-year-long flight, unexpectedly arrive to the Shedar system after less than one year of local time travel.

But the "extra" member of the crew, a stowaway, Lobanov meets strange more or less human-like creatures that escort him and his mates to the underground city.

The commander of that ship explains that their home planet is populated only by the two kinds of bionic robots - executors and far more advanced rulers.

After some troubles, boys counterfeit the recharging request from the power plant and burn up all robots at the planet, making it free for people from the space station.
