Humanoid robots go for knockout in high-tech Vegas fight night
Two robots the size of schoolchildren stepped into the ring at BattleBots Arena.
The human-like combatants stumbled a bit as they swung and kicked at each other in the Ultimate Fighting Robot (UFB) match, curiosity mixing with cheers from spectators at the event on the edge of the Consumer Electronics Show in Las Vegas.
The contenders were a departure from the usual lineup at the event, known for wheeled machines equipped with wrecking tools.
