Assemble your robotic model of the giant, mighty, ferocious Tyrannosaurus rex. At 11 inches tall and 19 inches long, REX commands respect! 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 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!
