The ‘Shared Guide Dog 4.0’ is the vision of a technical assistance system that navigates urban spaces fully autonomous so that not only seniors but even blind people can use it.
The idea originated in 2019, when the University of Applied Sciences Hamburg (HAW Hamburg) put a strategic focus on micro mobility in urban areas. In 2020, the first research project was launched with HAW Hamburg's own funds (01/20-12/23), and its project title, “Shared Guide Dog 4.0,” has long since become the product name.
“Guide Dog” symbolizes that this mobile robot should navigate the person being guided as well as a guide dog. “Shared” stands for the idea that this complex new development is available for hire at a train or bus station, is used by several people, and leads to greater participation and inclusion by maintaining the independence and mobility of users. “4.0” symbolizes the term “Industry 4.0,” meaning that the mobile robot is equipped with a wide range of sensors.
The idea was so well received by all involved players that it was impossible to simply stop when the first project was completed. Furthermore, the International Transport Summit held in Hamburg in 2021 came along with Hamburg setting up a “Test Track for Autonomous and Connected Driving (TAVF)“, and the “Shard Guide Dog 4.0“ had become part of this networked community. A series of projecs follwed: the IFB Hamburg funded project “AI-Based Puddle Detection” (05/22-04/23), the BMV funded project “GehwegNavi” (03/24-08/25), and currently, a start-up is being prepared in the BMFTR funded transfer project “SafeWalker”. Meanwhile, the “dog is even dancing“ at the European banquet in Brussels, as the European Commission awarded it third prize in the“older people” category at the European Road Safety Awards 2025.
Researchers must address the challenges of navigation in urban environments, such as the fact that GPS does not work reliably near tall buildings. They must deal with similar safety requirements that automobile manufacturers also have to solve in public spaces. In addition, Shared Guide Dog 4.0 must also be able to navigate away from roads, for example on sparsely marked park paths, where puddles, bollards, playing children, and romping dogs lurk as static and dynamic obstacles. Above all, however, researchers must be good listeners when it comes to understanding the specific needs of different user groups.
