Many companies have already launched their first prototypes, but the robots developed by the Polytechnic University of Catalonia (UPC) and CARNET have a standout feature — they’re able to go up and down stairs, according to the press release.

The new robots were developed by the UPC and CARNET, a research hub located in Catalonia (Spain) specialized in mobility and innovation funded by the Volkswagen group, SEAT, and the UPC itself.

The Institute of Robotics and Industrial Informatics (IRI) coordinated the project, which began in 2017.

These robots will be used for last mile delivery and will start operating in a pilot phase this year in Esplugues de Llobregat (Spain), Hamburg (Germany), and Debrecen (Hungary).
