Professor Robot is a world-famous inventor of robotics technology. Experts consider his humanoid robots and artificial intelligence to be the most advanced in the world. On this occasion, he is called in to solve a completely different problem. A gang of notorious vandals has been graffitiing and causing enormous damage to the public tram system, evading the police for months.

This book has a comic-book flavor with influences from Batman, Ironman, and The A-team. It's a fun read for late elementary, junior high-school and older readers with an interest in science fiction, coding, or STEM.
