LEGO SET 31164 - Alternate build | Space Robot
Explore the Infinite Possibilities of LEGO Set 31164-1 – Space Robot Alternate Builds
When LEGO released the 31164-1 Space Robot as part of its Creator 3-in-1 2025 lineup, it wasn’t just adding another fun mech to its catalog—it was launching a platform for endless space-themed creativity. With its futuristic color scheme, jointed limbs, and functional design elements, the Space Robot is a dream for builders who love robotics, sci-fi, and modular innovation. But what truly unlocks the power of this set is its alternate build potential. With only the pieces in the box, LEGO fans around the world have designed everything from iconic robot duos to Star Wars-style droids and imaginative mecha creatures.
Alternate builds stretch your imagination in ways standard instructions can’t. Instead of one fixed design, you’re free to reconfigure the robot’s parts into entirely new characters and machines. Want a mini space cruiser with working hyperdrive details? You got it. Craving a cute yet complex Wall-E & Eve duo? Done. From fearsome RoboSkulls to eight-legged spider tanks, this set empowers you to explore the outer reaches of sci-fi design without needing any extra bricks.
These MOCs (My Own Creations) are especially useful for young builders, educators, and AFOLs (Adult Fans of LEGO) looking for variety and inspiration. The alternate models breathe new life into your set and challenge you to think differently about the bricks in your hands. Below, you'll find a fantastic lineup of alternate builds created by talented designers using only the parts from LEGO 31164-1 – each with a link to full instructions so you can build them yourself.
