Based on the old Richard Matheson story "Steel," which also inspired a "Twilight Zone" episode back in the day, this version is more of a father-son relationship movie than a 1950s speculative fiction romp, although that's not to say the special effects and science fiction aspects don't take center stage when they're happening.
It's 2027, and robot boxing is a thing, and has been a thing for a while, long enough for there to be has-beens in the game. Has-been boxer and robot boxer controller Charlie Kenton is played by Hugh Jackman, who while on the rodeo circuit trying to make a buck and running from debtors, learns his ex-wife has died and his son Max (Dakota Goyo) needs a guardian. To get back, Charlie makes a deal to watch his son for the summer in exchange for selling his parental rights, and buys a new boxing robot - Noisy Boy. He hopes to make all the money he needs with this robot, but his son insists that half the money is his. Yeah, road trip.
