Sphero 4X4 helps the lovely Sphero navigate all terrains and manage rough landings with bouncy moves. The shell protects Sphero from scratches and external damage while the specially designed flexi legs act as springs to smoothly allow it to overcome any obstacles. It helps it swim like a dolphin, jump around in the grass like a rabbit and rush through sand and concrete like a fast cheetah. With 50 places to attach the legs, the various positions offer different functionalities depending on the tricks you want to try… and the skills you have in manoeuvring your cute round fellow. Just out of the printer.... http://youtu.be/wNuqBAvhX-M http://youtu.be/X7Ksy6EV-hY http://youtu.be/hjrdxbrhHCo ALL RIGHTS RESERVED
