The comedian and former host of BBC Two’s The Apprentice: You’re Fired! will be joined on presenting duties by Angela Scanlon.
The duo will report on the robots and the teams, and obtain feedback from the judges.
Jonathan Pearce, best known for his work in sports broadcasting, will return as commentator.
The BBC has announced all the Robot Wars action will come from a new purpose-built fighting arena in Glasgow. State-of-the-art cameras capable of capturing every saw, claw, and flame-thrower will allow viewers to feel even closer to the action.
Following the format of the original series, broadcast on the BBC from 1998 to 2002, teams of amateur roboteers will see their imaginatively armed creations go head to head with the sole purpose of destroying their competitor.
The new six-part series promises a “raft of technological advances”.
“I am thrilled to be presenting Robot Wars,” said Ó’Briain. “For too long, the schedules have cried out for a show in which dedicated amateurs, toiling day and night, handcraft sophisticated automatons built on the delicate interplay of handwired servomotors with custom-built circuit boards and fingertip motion control, just to see them get smashed to pieces by a dustbin carrying a massive hammer.
“It’s war, and how I love it so.”
Scanlon, who has worked for RTÉ, said: “I’m so excited to be joining such a legendary show that, after all this time, still manages to make people squeal with joy. I cannot wait to see the robots in all their metallic glory playfully destroying each other.”
The series was last broadcast on Channel 5 from 2003 until 2004.
