Thymio geometry
In order to model any kind of robot robot with GeoGebra, we need to base the design on a reference system attached to the robot. Here we are going to create the geometry of the Thymio robot. Quite naturally we select the pen hole position, point , as the reference point, together with an orientation angle . By setting the pair the robot can be placed anywhere in the working plane.
These are the elements we need to create:
- the position of the robot, center point
- the orientation angle of the robot
- the robot direction unit vector
- the perpendicular direction unit vector
- the position of the two wheels
- the corner points of the outline
- the straight and circular segments of the outline
