Extract the names of the team involved to perform inception on Robert. Separate them with a comma.

Cobb and Arthur are "extractors"; they perform corporate espionage using experimental dream-sharing technology to infiltrate their targets' subconscious and extract information. Their latest target, Saito, is impressed with Cobb's ability to layer multiple dreams within each other. He offers to hire Cobb for the supposedly impossible job of implanting an idea into a person's subconscious; performing "inception" on Robert, the son of Saito's competitor Maurice Fischer, with the idea to dissolve his father's company. Saito promises to clear Cobb's criminal status, allowing him to return home to his children.

Cobb accepts the offer and assembles his team: a forger named Eames, a chemist named Yusuf, and a college student named Ariadne. Ariadne is tasked with designing the dream's architecture, something Cobb himself cannot do for fear of being sabotaged by a projection of his late wife Mal. Maurice dies, and the team sedates Robert into a three-layer shared dream on an airplane to America. Time on each layer runs slower than the layer above, with one member staying behind on each to perform a music-synchronized "kick" to awaken dreamers on all three levels simultaneously.
