Unlimited creative building…in one high-tech set! As children snap, pop and click together our interlocking pieces, they make fascinating creations—and naturally develop an interest in technology while boosting problem-solving skills! Even children with no previous robot-building experience will enjoy inventing and designing robots, critters, cars and more—plus, a pull-back motor and wheels put the pieces in motion, so kids can play with their creations! You get 49 interlocking pieces, plus wheels on a pull-back motor, 1 light-up piece with a replaceable battery, and an activity guide.
