On my way home this little fella crossed my paths. Right now in Hamburg the German parcel delivery service Hermes (as part of the Otto Group) experiments with self driving parcel delivery robots. Otto is one of the last standing competitors of Amazon in Europe. In case anyone asks how the robot rings the bell. As soon as the robot approaches the house of a customer, he receives a text message on his or her mobile phone. It is interesting to know that Hermes and Otto don't develop the robot themselves but with the help of the Estonian company Starship Technologies. It's CEO is not a newby. Ahti Heinla is known as Co-Founder of Skype.
