ABC has renewed “BattleBots” for a second season, the network announced Thursday.

Following the summer ratings hit “Celebrity Family Feud,” the six-episode first season of “BattleBots” earned an average of 5.4 million total viewers and a 1.7 rating among adults 18-49.

Season 2 will keep the single-elimination tournament format of the first, but will double the size of the field to include expert roboticists, garage builders, families on a mission and past winners returning to defend their turf.

ABC’s “BattleBots” is a reboot of the Comedy Central original of the same name, featuring hosts Bil Dwyer, Sean Salisbury and science guy Bill Nye as a technical expert. The show ran for five seasons before being canceled in 2002.
