Created by ECAL's past and present students, DRM Chair provides a limited number of use before it self-destructs. A small sensor detects when someone sits and decrements a counter. Every time someone stands up, the chair knocks a number of time to signal how many uses are left. When reaching zero, the self-destruct system is turned on and the structural joints of the chair are melted.
Earlier this year at ECAL (Lausanne/Switzerland), students were asked to develop projects using the Thymio robot during a one week workshop. Students worked then in group with the task to make Thymio(s) write a word, all those words was then put together to form a sentences that you can discover in the video below.
