Robots and outer space are a double win! Future explorers can build an authentic rover, like the one that landed on Mars. Nine other space machines, from a shuttle to a moon lander, can also be created with this 237-pc. set. The remote control activates up to three motors, to turn wheels and pick up ground samples. Requires 6 AAA batteries, not included. From Thames & Kosmos, for ages 8 yrs-teen.
