This project describes the same robots as those of previous projects, and also uses a solar pulsing charge and discharge control circuit—a solar rotating robot. Through these projects, we can understand a new type of robot drive.
The robot of this project can be regarded as a “solar windmillâ€. The energy that the windmill rotates is wind energy, and the energy of the “solar windmill†is solar energy. When there is the sun, it turns and converts solar energy into kinetic energy. The same pulsating charge and discharge control circuit as the previous ones is used, and the effect of the operation is that the sun will charge the sun for a while and then turn for a while, the sun will rotate faster; if the sun is hot enough, it can be almost continuous. There is no pause in the middle of the rotation, and at this time, a large amount of vibration will occur, and the robot will also move as a whole.
Driving principle
The driving principle of this project robot is very simple, it is the drive mode of the drive motor rotation, but somewhat different from the usual application: the general motor drive structure, the motor is fixed, the motor shaft is rotating; and the structure of the project is exactly On the contrary, the shaft of the motor is fixed, but the motor itself is rotating - the shaft of the motor is fixed on the base, and the motor, solar panel, control circuit, etc. are all bound together with the motor and can be rotated. Said that in addition to a fixed base, other parts will rotate with it.
Mechanical structure
In this project, the mechanical structure of “fixed motor shaft and rotating the motor itself†is not as efficient as “the motor itself is fixed, but the motor shaft rotatesâ€. After all, in addition to burdening the actual load, the motor must be burdened. The weight of the motor itself. In practice, this method is not generally adopted. If it is really used as a solar windmill, a reasonable method should be to reduce the driving load as much as possible, except that the motor and the control circuit should be fixed on the base so as not to follow the rotation; Should consider the installation angle of solar panels, as far as possible to the sun in order to fully obtain solar energy; it is not enough to fix the installation angle of the solar panel at least, not to say that the solar energy will be so unstable (turn to the sun's angle is the efficiency The higher the speed is, the slower the efficiency is.
