Build a humanoid robot that walks forward on two legs and pivots to avoid obstacles in its path. An awesome stag beetle model moves backwards or forwards in response to an obstacle, and opens and closes its pincers. Construct a funny crocodile model that wags its tail if no object is in sight, but then opens its giant jaws when an object approaches. Using an additional smartphone and tablet, you can even hack together a cute little spy-bot that roams around and streams video back to the tablet screen. A cool dual-rotor drone model rotates its rotor blades 90 degrees. You can also assemble other fun robots including a robo-dog and robo-dino. After you have learned how the technology works, you can build and program your own robots using the kit’s 230 building pieces. WARNING: CHOKING HAZARD - Small Parts. Not for children under 3yrs.
