Localization and navigation are fundamental issues to mobile robotics. An approach for localization and navigation for a mobile robot in indoor environment is proposed in this paper. In this approach, ...

For mobile robots localization, using QR code fixed on the ground and a camera on the robot to scan it is handy. However, getting the orientation of the robot isn't quite straight forward.

This is a demo of a mobile robot recognizing the QR code and calculating its position in the global map. The code is brief but very practical.

Concept design uses QR codes to give time and place information to smartphones and other devices with artificial eyes. The QR code constantly changes to reflect the new time.

But QR codes still aren’t easy to use. Software to read them isn’t even built into the camera apps on popular smartphones, and scans using QR apps often fail or miss.

The QR Code Clock operates by displaying a series of QR codes that change every minute. Each QR code represents a specific time, which can be scanned by a smartphone or a robot to reveal the ...

This project for the Hackaday Prize solves the problem of indoor navigation, and it does it in an amazingly clever way. This is using QR codes for navigation, but not just any QR codes.

It turns out QR codes aren't just for marketing. Something very much like a QR can help a manufacturing robot quickly find its position--something that is especially crucial in the ultraprecise world ...

Localization is essential for the autonomous navigation of a mobile robot. Because the error of the internal dead-reckoning localization increases with time, th ...
