If you are a US university student, you will soon have the option of getting your takeaways delivered by robot thanks to the ambitious expansion plans of Estonian startup Starship. Started in Estonia by ex-Skype entrepreneurs Ahti Heinla and Janus Friis, the company about to dramatically increase the number 6-wheeled delivery bots roaming the streets, following a $40m Series-A funding round. While questions are being raised about the economics of such a robot delivery business, the company is unabashed. Lex Bayer, chief executive, tells Sifted that the company plans to expand to 100 US university campuses over the next two years. With a typical fleet of robots being somewhere between 25 and 50, that could mean more than 5000 robots in service by 2021.
