2.1. Physical level
First section of the workshop was dedicated to the introduction of the robot. Children were shown two Lego
Mindstorms robots and some of the robots’ characteristics were described. This particular type of robot was chosen
because Lego Mindstorms robots are often used for educational purposes, in elementary school (Lin et.al., 2010),
high school (Church et.al., 2010) and as well in college (Cuéllar & Pegalajar, 2014). Main parts of the robot were
presented to them - motors, touch sensor, ultrasound sensor, color sensor and the “brain” (i.e. central processing unit
of the Lego Mindstorms robot, also called “the brick”). Children were then presented with printed cards, each of
them containing the picture of one particular part described earlier. They were then handed a single piece of paper
with two different boxes. One was labeled “Robot FEELS with this parts” (Figure 1a. – 1) and the other one “Robot
ACTS with these parts” (Figure 1a. – 2). Their task was to put each card in appropriate box. Most interesting part of
this experiment was to see how they would label the brain of the robot. Figure 1.a shows an example of this
experiment, with different cards categorized in two boxes.
After finishing this step, children were then given the task to design their own robot, using familiar parts. Again,
we used cards with pictures of various parts on them. Children were given a paper representing the base of the robot
with 9 (nine) available slots that could be filled with one robot part of their choosing. They had at their disposal
multiple cards depicting the same part so they could make many different combinations of robots. Figure 1.b depicts
one example of robot design made by one of the children.
