The Adventures of the Electronic (1979)

Professor Gromov constructs a robot called Electronic, which looks exactly like Sergey Syroezhkin, a 6-grader from one of Odessa (USSR) schools. The robot also acts a lot like a human, and its dream is to become a real man. Electronic escapes from the professor's lab and accidentally meets Sergey, his prototype. Meanwhile, a gang lead by Stump is trying to kidnap Electronic to make him steal pictures from museums. For this purpose they send their hitman Urrie.
