QR codes simplify robot navigation

Communicating commands to a robot, particularly in terms of new locations, is now easier with quick response codes.

Being able to instruct a robot in terms of where it should navigate, especially when it comes to new locations, has been a considerable struggle that has previously needed complex technologies, but that could be resolved with something as simple as QR codes.

Previously it was believed to require sophisticated machine vision, and tech such as Bayesian particle filters.

However, recently, this planning was constructed in a very different way, using QR codes to help to guide robot navigation issues of localization. The issue is in the concept that if a robot were to bring you a glass of water or a soda, then that machine would first need to know where it is located and where the drink can be found. Therefore, the robot would essentially require a map and would need to be able to recognize its own location on that map at any given moment.

QR codes are allowing some of the issues within that process to be sidestepped.

QR Codes - Robot NavigationAfter all, to truly become practical, the robot would also need to be able to create its own maps be “observing” its surroundings and still be able to understand where it is located on the maps that it has constructed on its own. This has been labeled the SLAM problem, which stands for Simultaneous Localization and Mapping.

The inability to overcome this problem has limited robots to being able to navigate only around a constructed environment where they are programmed for very specific tasks. However, by coming up with a way to give these machines the opportunity to properly gauge and interact with their environments – and their own position within it – then this could present far greater opportunities for their use. Previous methods have involved using advanced technology to be able to label an environment with markers such as RF beacons. However, more recently, a much simpler marker has been employed.

This marker involves simple scanning of QR codes – often called by the nickname of “robot vomit”. These quick response codes are often seen in advertising and product labels, but by sticking them on the features of a space, including doors and walls, it can help robots to better understand their own environments and how to function within them.

QR codes from Visualead make their way into China

QR Codes ChinaThe near invisible quick response barcodes are looking for Chinese local investors and partners.

Israeli startup, Visualead, has just announced that it has launched its near-invisible QR codes in China, and that it is now looking for investors and partners in that country.

These barcodes are unique because of the fact that they are nearly invisible but highly scannable.

This helps marketers to overcome their current concerns with the fact that QR codes take away from the visual appeal of their advertisements. Visualead’s launch in China has been a very strong one as it began its entry to that market by becoming the winner of the Growth Stage Competition at a worldwide mobile internet conference last week.

The near invisible QR codes company is very positive about its launch in China and its successes so far.

According to Uriel Peled, the CMO of Visualead, “It’s very exciting”. Now that the company has won a quite a notable award, it intends to continue to make a big splash in the country by helping brands, marketers, and others to apply its QR codes technology in order to be able to improve communication between them and consumers in China.

Visualead was first launched in January. It functions by giving everybody the chance to generate QR codes through the uploading of a photo onto the website, merging the image and the barcode together. This is considerably different from the older versions of the barcodes which were limited to a black and white square made up of pixels.

The benefit of the Visualead nearly invisible barcodes, says the company, is that their highly improved visual appeal will help to encourage consumers to scan them. This is because they are more attractive and are therefore more likely to build engagement with the people who see them and who carry smartphones.

Though the generation of the QR codes is a part of a free service, Peled has said that the company has intentions to broaden its premium service. That is a paid version geared toward small businesses and enterprises, which can buy their barcodes for use on virtually any kinds of print materials, including retail products, banners, and brochures.
