The most complex model based on the large NASA model, enlarged to 200% to allow for the installation of stepper motors and servos for wheel propulsion, the drilling arm (MAHLI), and the creation of a rotating and tilting camera (ChemCam). The model does not include electronics with a Micro:bit. (The feasibility model was built with an Arduino Nano Every.) This project does not address the installation of a control unit; that is left to the modeler's choice. Power is supplied by two Li-ion 18650 cells and 5V voltage stabilizers.
