This page summarizes some work made in Los Gallardos (Almería, Spain) by children doing a robotic workshop.
the system
The final system is built using two robots one on the top of the other, like this:
The wheels of the upper Thymio are connected to gears transforming the horizontal rotation into a vertical rotation acting on the arms. This is done using a knob gear, but could be done with other gears that allow to make a 90 degrees angle:
The whole gear box is attached to Thymio using an elastic band.
