We've all been waiting to see how the fabled WoWee Roboquad crawls. Now we know. The four-legged bot moves in all directions, has 3 different speeds, and a deep IR scanner to spot movements up to 13 feet away. Its sound sensors are reactive, and it can tell the difference between dark and light. Kind of like the LEGO Mindstorms NXT, but a lot less work. $119.
