Chances are you can recognize a McDonald's sign from a mile away with one eye closed. Meanwhile, your Roomba can't see a wall until it hits one. That's because human eyes see patterns and robot eyes see a creepy red-hued targeting display (we're not entirely sure we got that one right). Evolution Robotics - the guys behind the navigation system in WowWee's Rovio
- have developed a system that lets robots (or even cell phones) recognize objects such as book and album covers.
