Thyssenkrupp Elevator is testing TeleRetail delivery robots to make lift maintenance safer and more efficient. Self-driving vehicles will be a normal part of street scenes in smart cities of the future. Whether moving people or goods, autonomous vehicles promise greater efficiency, safety and smoother logistics. Compact delivery robots will ensure that packages get to their destination by the quickest route possible. TeleRetail is developing driverless delivery vehicles and for Thyssenkrupp Elevator they could be an optimal logistics solution for elevator servicing. Together with the software developer TeleRetail, Thyssenkrupp launched a pilot project in which delivery robots will transport spare parts and other material to maintenance job sites. The delivery robots are just 85 cm wide and suitable for traveling on sidewalks, thereby avoiding road congestion.
