Video: This Robot Can Find Waldo in Four Seconds

09 August 2018

Chalk this up as straight-up cheating.

Someone has created a robot built with one specific purpose: to find Waldo from the iconic “Where’s Waldo?” books.

The robot is an arm that is controlled by a Raspberry Pi using the PYARM Python library for UARM Metal.

The robot extends over the book to the pages and uses OpenEV to find and extract faces from the photo. The faces are then sent to Google Auto ML Vision service, which compares each one against the trained Waldo model.

Redpepper, a creative agency that built the robot arm, said the system has a matching capability of 95 percent or higher and if there are multiple Waldos in a photo it will point to each one. It can also find Waldo in about 4.45 seconds.

That’s probably much faster than your child, or you, could ever find Waldo. But, then again, it is totally cheating.
