The most complete and advanced Lego robot we've seen, EV3 will walk, talk, play games, and perform a variety of programmable tasks. The large-scale 16" robot can be programmed using a smart device and can also be controlled using a handy remote control that you build yourself.

The set also includes instructions for 17 different robotic designs that can be constructed with the provided pieces, each of which offers unique features and tasks. The models are by no means simple to build or program, so this set is not recommended for children younger than ten years old.


  • Fully functional robot can perform any number of tasks
  • Set includes 17 different robot designs
  • Can be controlled via the EV3 programmer app or with a remote control


  • Not recommended for children under 10
  • Software can be glitchy with some Android devices
  • Goes through batteries quickly

Best Value: LEGO Creator 3in1 Underwater Robot

If your little Lego builder is not quite ready for a state-of-the-art (and very expensive) programmable robot, the 3in1 Underwater Robot is an excellent starting point. The 6" tall robot figure is easy to assemble, and even though the package says 7+, many experienced Lego builders as young as five could build this with a little supervision from parents.

It does not walk on its own, but since all the arms, legs, and even fingers are posable, the completed robot can provide hours of Lego fun. What's more, the same set can be used to build a submarine and an underwater crane with a functioning grabber claw. This set includes no electronics, metal parts, or stickers so that it can be fully submerged in water for bath-time or pool-time fun.


  • Easy enough for younger kids
  • Inexpensive
  • Works for underwater play


  • No mechanics or movement
  • The robot is pretty small
  • Only one model can be built at a time

Best Cute Factor: Lego Ideas Wall-E

Walle HeroSource: Lego

Here's the perfect robot for Disney fans and Wall-E lovers. This detailed replica of the famous waste management robot features posable arms, head, eyes, and hands, as well as a trunk that opens and closes, just like the movie. Although he won't roll on his own, his tracks roll smoothly with a little push.

With almost 700 pieces, Wall-E is not an easy build. He's recommended for kids over ten years old. Once he's been constructed, this limited edition Wall-E is considered a collector's item. Since Lego no longer makes this model, it does come at a pretty hefty price point.


  • Pose his eyes, head, and neck for classic Wall-E expressions
  • Adorable robot design looks just like the movie
  • Roll him, pose him, or open and close him for hours of play


  • Difficult for children under 10 to build
  • Expensive
  • Discontinued by manufacturer so that replacement parts will be a hassle

Another of Lego's impressive Mindstorms robots, the NXT can interact with his builders using his artificial senses of sight, touch, and sound. He can distinguish colors, identify obstacles in his path, and interact with your touch. By using a computer to program the NXT, he can be taught a multitude of tasks and functions, such as talking, closing doors, pushing buttons, or fetching an item.

  • Robot interacts with lifelike senses of sight, touch, and sound
  • Pieces can be used to invent any number of new robots
  • Programming software is open-ended to create new tasks and functions


  • Expensive
  • Only works with computer software, not with other smart devices
