Resumen

This work presents the generation of the precession motion of a CanSat Rover-Back educational picosatellite falling to earth for future space exploration missions using the conventional design of reaction wheels, together with the basic concepts of electronics, mechanics, physical sciences and mathematics, being a technological innovation (STEM). For the modeling and operating parameters, are presented mainly the mass, the distance difference between the point where the structure hangs or pivots and the center of mass, the control of the angular velocity in the motors performing a change of direction of rotation. The results show the generation of a sinusoidal signal of the precession speed in revolutions per minute (RPM) of the prototype, demonstrating its validity, and the variation of its speeds in RPM of the two motors.
