QR Codes Used in Robotics

Wednesday, December 4th, 2013

One of the biggest challenges in navigating robots is making the machines become aware of their location. In short, how does a robot know where it is and where to go, as well as how to get there?

This has baffled robotics experts for a very long time, often coming up with complicated and highly technical solutions. But what if we tell you that you could use a QR code to help robots become aware of their locations?

In the past, one of the ways for robots to identify their location is via near-field communication or radio frequency signals. One of the real-world applications for this was seen at a McDonald’s restaurant in Singapore.

According to the report, McDonald’s used NFC for its Happy Table campaign, where kids can tap their smartphones on the table to play a racing game. When they hold the smartphone over the table, a car appears on their screens. They would need to move the phone all over the table to finish the course. The table was set up with a series of NFC chips, and if you do not hit the next NFC chip, that means it is game over for you as you crash to the side of the road or fall off a cliff.


That might be an easier way, but there is something much easier than that: using QR codes.

Fitted with a camera, robots could be programmed to read QR codes. The QR code would contain information on the location and the robot would be able to know where it is. For example, scanning a QR code on the living room the software could tell the robot that the refrigerator is on the left and the next room is the kitchen. This will allow the robot to go to where it is supposed to go.

As early as now, Aldebaran Robotics is already working on the idea. You can see it from this YouTube clip:
