Leonardo Robot - isn't this the cutest robot ever?

Uploaded on Dec 21, 2008

Taken from the BBC's Horizon: "Where's my robot?"

Leonardo picks up on the positive "Elmo is good" vibes that the guy is giving off about the Elmo toy and responds positively by looking excited and reaching towards it.

When they guy takes away Elmo and replaces it with a Cookie Monster toy and gives off negative, "Cookie Monster is bad" signals, Leonado reacts accordingly and backs away.

Leonardo hasn't seen either toy before but has been programmed to pick up the emotional vibes given off by humans and react accordingly.

Leonardo: Hierarchical Task Learning with Social Scaffolding

Published on Feb 17, 2015

In this video we see how Leonardo is capable of (1) learning new skills via social guidance and (2) reusing parts of those skills in new social tasks. In this scenario, Leo learns from Jesse's guidance how to manipulate the puzzle boxes through switches. Then, Leo learns which blocks Jesse wants him to use to build a sailboat. Along the way, Leo re-uses his previously learned skill of manipulating the puzzle box in order to acquire the necessary components.

Leo Learning Faces Demo

Published on Mar 27, 2015

The video shows a single interaction wherein Leo is introduced to two new people for the first time. Leo learns both of their names and builds a model of each of their faces. Leo's face recognition abilities are tested by asking him to find each of the people as they move to a few different locations in the scene. Leo scans the scene, and when he finds a face that matches the query, he points to it. When asked to find someone who is absent from the scene, Leo looks around for a while, then shrugs to indicate that he cannot find them.
