- Everyone loves a good "Where's Waldo?" puzzle — unless you can't actually find Waldo, then it starts to get frustrating.
- Don't feel too bad: One company actually built a robot that can find Waldo faster than most humans probably could.
- The robot, called "There's Waldo," uses computer vision and machine learning to spot Waldo — it's been able to find the hidden character in as little as 4.5 seconds.
- Here's how "There's Waldo" works:
Creative agency redpepper built a camera-mounted robotic arm and connected it to Google's machine learning service AutoML, which analyzes the faces on any given page to find Waldo.
If "There's Waldo" can find a face in the puzzle with 95% confidence or higher, it will move its mechanical arm to point at any and all Waldos on the page with its creepy rubber hand.
The robot arm, which is controlled by a tiny Raspberry Pi computer, was coded with Python to extend and take a photo of the "Where's Waldo" puzzle.
