Build, code and control your own robotic creature. The Building and Coding STEM Dinosaur Robot lets you build a robot T. rex. No apps are needed. Just use the handheld controller to move it around in all directions, light up its eyes and play sounds. Or, program your own motion sequences that start with the touch of a button. The built-in guardian mode even transforms T. rex into motion-sensing alarm with a ferocious roar. Includes an illustrated guide that reinforces STEM learning. Ages 8+.
