Orbot and Cubot

Orbot (オーボット) and Cubot (キューボット) are two small robots from the Sonic the Hedgehog series created by Doctor Eggman to be his assistants. Orbot is a red orb-shaped robot that usually points out Eggman's mistakes, sometimes inadvertently insulting him. Cubot is a yellow cube-shaped robot with a failure in his voice chip that makes his voice and accent change.

Orbot and Cubot appear briefly in most parts from the crossover Worlds Collide, usually doing tasks for doctors Eggman and Wily such as giving information, serving coffee, and assisting in building machines.
