Sex robots are anthropomorphic robotic sex dolls that have a humanoid form, human-like movement or behavior. In 2015, Robot ethicist Kathleen Richardson called for a ban on the creation of anthropomorphic sex robots. As of 2018, no fully animated sex robots have been created by a number of inventors.
