Here's what they did:
* Started with an ambitious plan: They wanted to build a robot that could help them with their chores.
* Struggled with the instructions: They got confused and frustrated with the robot building kit, ending up with a "glorified box with wheels" instead of a functional robot.
* Tried to cheat: They considered copying another student's robot, but ultimately decided against it.
* Crashed and burned: Their robot didn't even come close to working, and it ended up getting destroyed during their presentation in front of the class.
The entire robot project was a source of great stress and frustration for Greg and Rowley, ultimately leading to their suspension from school.
