Interactive Robotics

We created a spin-off Interactive Robotics that will bring the RoboTutor to schools. Go here to found out more.

RoboTutor in Jeugdjournaal

The RoboTutor went to St Joseph elementary school in Leiden today. The RoboTutor visit was filmed and reported on the Jeugdjournaal. Children liked the RoboTutor, and said the robot was fun to have over. See the whole item here (Dutch).

Affective Body Language of Humanoid Robots – PhD Thesis of Junchao Xu

Junchao’s PhD thesis on emotional expression through body language is available here!

Here’s a summary of his work:

Robots will be increasingly integrated with daily activities of humans. The robots will cooperate with us, assist us, and accompany us. Social abilities are important for such robots to interact with us harmoniously and to be accepted by us. The expression of affect is one of the social abilities. The expression facilitates human understanding of a robot’s behavior, rationale, and motives, and increases the perception of a robot as trustworthy, reliable, and life-like. Most of the current approaches focus on categorial emotional expressions, often with a focus on facial expressions. A few studies addressed bodily emotion expressions that are separate body actions. For enduring human-robot interactions, there is a lack of models and methods for bodily mood expressions that the robot can show during execution of functional behaviors. In this thesis, we develop body language for humanoid robots to express mood at an arbitrary time, even while executing a task, and the mood is represented in dimensional scales. We create a model for robot mood expression, validate the model, and investigate users’ perception of the robot mood and effects of the mood expression on users in dyadic and group settings.

Robotutor visits primary schools

In 2015 Robotutor gave several lectures at some primary schools in the Netherlands.

On march 3rd he was in action at basisschool “Los Hoes” in Haaksbergen.


After the lecture the children did some nice programming by themselves.


On june 10th he visited “De Boomgaard” in Utrecht.


Robotutor at iXcamp 2014!



On May 22, the Robotutor travelled to Arnhem for an event entitled “iXcamp 2014 – iXperium / Centre of Expertise Leren met ICT”. Teachers and students from universities, Hogeschool, high-schools, and primary schools showed great interests in the application during a speed-dating with our Robotutor. They were impressed by the natural behavior of the robot and the abilities to using PowerPoint for the lecture. The script-based authoring tool intrigued some teachers, because the development of this tool is tailored for non-programmers such as teachers. One of the teachers improvised a scenario using the authoring tool within just a few minutes, and the audiences were well entertained by her creation. When I introduced our study [1] about expressive coverbal gestures, one of the teachers was excited by the result that positive mood expressed by the robot body language induced positive arousal of students and may facilitate learning. She shouted out “Yes. No arousal no learning!”            —Junchao Xu, Ruud de Jong

Mood-modulated gestures for RoboTutor

Last month we marked an achievement mile, as we demonstrated mood-modulated gestures in RoboTutor. This was done as part of Junchao Xu’s research whether the mood of the robot had influence on the audience or not. Videos of the robot giving lecture with positive and negative moods can be found below:
