Build, code, and play — with mighty REX! Assemble your own robotic model of the giant, powerful, ferocious Tyrannosaurus rex. Use the handheld controller to command your robot to move around in all directions, light up its eyes, and play sounds, including chowing down on food and even farting! The special Code+Control wireless unit enables you to either directly control REX in real time or write and save sequences of commands for the robot to perform at the push of a button. No app or separate devices are required! REX makes hands-on STEM learning fun and accessible. First, follow the step-by-step instructions to assemble the robot and controller from more than 150 pieces using the included screwdriver and decorate your completed dino with stickers. At 11 inches tall and over 20 inches long, REX really commands respect! Then, learn the function of each button on the controller and how to combine those functions together into programs for your robot. With two motors and a flexible tail, REX can move in one of two modes: walking or gliding. Put REX into guardian mode and it will use its infrared sensors to identify intruders then unleash a ferocious roar! Finally, you can try out the suggested experiments to learn more about how the robot works and about the various electrical components found inside a robot.
