Researchers have built autonomous delivery robots that can climb stairs. Delivery companies are always on the lookout for the next big innovation in the sector. Some big names have also developed their own autonomous delivery robots, like Alibaba, whose robots are becoming ever more prominent in daily life in China. 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). These autonomous delivery vehicles would represent "a significant reallocation of the carrier's costs and would make the service more economical and efficient than with conventional vehicles," it continues.
