The ROBO-ONE competitions began in 2002 and have since focussed on humanoid robotics with participants judged on a range of tasks like timed dashes, opening doors, obstacle courses and a ball toss. Only the top scoring bots reach the final event –a boxing match with opponents trying to knock the other down or out of the ring. (Matt Roberts / Getty Images)

Some teams used image recognition cameras to lock on and attack, while others used infrared sensor arrays. Competitors are allowed to wirelessly beam data into the machine’s computer, but have no direct control once the fight begins. (Matt Roberts / Getty Images)

Participants pose with their robots during the 32nd ROBO-ONE tournament in Tokyo. Entry specifications have always been kept minimal to encourage mass participation. Over the years rules have progressed towards closer resemblance to human-like specifications for the bots with weight categories introduced in 2007. (Matt Roberts / Getty Images)
