Among them, the Robotics Invention System (RIS) from LEGO stands out as an excellent instrument for the quick and easy introduction of students to the exciting world of robots. We discuss here (1) how the sensor design represents an educational tool in itself and its educational benefits, (2) aspects of low-cost, RIScompatible new sensor design and (3) provide an example of new sensor design. While each of these later versions incorporated a considerable number of improvements in both software and hardware, the number of original LEGO sensors available is limited to a set of four: touch, light, temperature, and rotation. It is inevitable that after mastering the basic features of the system, the users contemplate the expansion of its system capabilities. Although third party, RIS-compatible sensors are available - for a price - there is a more rewarding way to add new features to a RIS-based robot project.
