Thames & Kosmos My Robotic Pet Tumbling Hedgehog STEM Kit 620500 Ages 7+ 172 Pcs

Thames & Kosmos My Robotic Pet Tumbling Hedgehog STEM Experiment Kit allows you to build a functional robot that responds to sound. This 172-piece set features a sound sensor that triggers the hedgehog to curl up, roll, tumble, and scurry based on your claps. The kit includes a 40-page full-color manual with a comic-book style story to guide builders through the assembly and experiments. Designed for ages 7 and up with help, or 10 and up independently, it offers a challenging yet rewarding introduction to robotics and engineering. The internal components like gears, motors, and LED lights are visible through the assembly process, providing a hands-on learning experience. Requires 4 AAA batteries (not included). All parts are present in original internal packaging; box has been opened but components remain unbuilt.  Thank you for visiting BuiltOnTrustCo!
