Assemble a fun frog  with blade shaped robotic back legs specifically designed to hop like a real frog. Made from polymer, the shape of the legs allows the frog to keep going. Watch the frog leap around but if it encounters an obstacle it may flip over. If it does this frog has a self righting mechanism that flips itself back over and continues hopping away.  Complete with a Learning Booklet, children can learn about robotics and engineering while building their own frog and they learn fun facts about poisonous frogs. This set is the perfect hands-on experience help your child learn about robotics in a fun-filled activity that the whole family can participate in! No glue required.
