Google has patented a technology where a robot can download the personality from a cloud based system just like the way how someone downloads an app on their phone.
The filed patent reads,
The robot personality may also be modifiable within a base personality construct (i.e., a default-persona) to provide states or moods representing transitory conditions of happiness, fear, surprise, perplexion (e.g., the Woody Allen robot), thoughtfulness, derision (e.g., the Rodney Dangerfield robot), and so forth.
In common terms, the robot could be programmed to mimic “a deceased love one” or a “celebrity”. The underlying technology involved in building this system has been patented by Google.
Google’s patent allows robot to react to one’s facial expressions and act accordingly, there by monitoring a person’s digital profiles to establish a personality that best suits him/her.
The patent also reads that the robot could be programmed to give a desired look as well as interactability for the robot, which is a subject to change by the user or by the robot. The robot interface is customized to provide a desired personality for the robot. The profile of the user may be linked to other social networking profiles which the user has created, in such a way that the robot could access up-to-date and pretty accurate information regarding the user .
Although it sounds very cool and sci-fi, there is no guarantee that Google would develop this in full-fledge and would roll-out this as an actual product.
