Stephen Felk with Voltronic in 2016.

Stephen Felk is a BattleBots competitor from San Francisco, California. Felk is best known for his highly successful Battlebots entrant, Voltronic (known as Voltarc prior to season 2.0), which he built in the kitchen of his apartment using salvaged electric scooter parts.

Felk competed with Voltronic in all seven Battlebots tournaments, reaching the final round three times, but failed to win a championship. Notably, Felk is the only Battlebots competitor to face the same opponent on three separate occasions ( Vlad the Impaler built by Gage Cauchois). Felk lost all three Battles. After his first defeat, Felk maintained a sporting rivalry with Cauchois throughout the the original Battlebots run.

Felk is also well known for his passion for Battlebots and robotic combat as a whole. He is also remembered for his pro-wrestler esque manner of speaking during interviews.

And so I think deep down in our psyche, there's thi..there's this feeling and repoire with violence that we really like. It's like pro-football." - Voltarc vs Bender mid fight interview.
