Robot revolution - James Patterson

After a few early glitches in their relationship, Sammy and his 'bro-bot' E are now best friends. In fact, E is such a valued member of the family that the other electronic members of the House of Robots are feeling sorely unappreciated. And when Sammy's inventor mom becomes distracted by a top-secret project, the robots soon begin to fall into disrepair.

Cue a robot revolution, with the droids wreaking harmless havoc in the house! Armed with pranks like glue in the shampoo bottles and flying toast missiles, the robots demand to be cared for. It's up to Sammy and his sister Maddie to keep the peace until his mom reveals her secret project... and why it was worth the wait.
