Roly Poly Robot will tumble, fumble, stumble but will always find a way to right itself up. The moment you turn it on, Roly Poly will speed away on its two cyclonic wheels. The engineering genius behind this well thought-out machine enables it to get on its 'feet' whenever it tumbles and then will continue on its new path of exploration. After assembling one worm gear and less than 20 parts, your mechanical marvel is ready to amuse any household pet. You can add your original work of art (drawing), or picture of your favorite person or pet and put it inside the Roly Poly's dome. Very easy to assemble, this "JR Science Series" robot is ideal for robotic workshops, after-school programs, special events, gifts, science enrichment camps, and classroom activities.
