Professor Robot and the Gang of Vandals

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.

The Professor enlists the help of his precocious grand-daughter and her geeky brother to help his team of robot engineers. But they will need to upgrade and push their robots to the limits to have any hope to catch them.

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.
