Description
The school invention showcase should be Tessa Bell’s big moment. Instead, Parcel—the yellow delivery robot her fourth-grade class worked so hard to build—vanishes from its supervised hallway route.
Tessa and her best friend, Malik Reyes, have a mystery to solve. The robot’s recorded stops point toward a custodian’s cart, a visiting middle-school robotics team, and a strange route code that makes no sense. As rumors race through the school, Tessa starts to suspect people before she understands the clues.
With the help of their teacher and a careful look at camera markers, data logs, and programming rules, the students discover that a tiny mistake can send a machine in circles—and a careless accusation can hurt a real person.
Funny, fast-moving, and packed with hands-on STEM thinking, The Case of the Runaway Robot is a school mystery about friendship, evidence, and asking better questions before pointing fingers.
