House of Robots. The Robots Went Crazy!

Sammy now goes to school with a robot! Sammy's mom is a first-class engineer, and their house is full of robots. But Sammy has to solve a challenging puzzle: why, when another robot appears at school, which clearly tries to compete with Sammy's robot, does Sammy's "robot brother" start to behave very strangely in class? So much so that the "robot brother" is decided to be "expelled" from school, and mom's research is called into question. Sammy conducts a real detective investigation to defend his family's honor and remain loyal to his friend.
