We’ve been working on the power system for our Spirit II Mars Rover, which, like the real Spirit robot on Mars, will be solar powered.¬†We plan to use four small solar panels. Each one is about 7″ x 9″ and delivers about 9.5 Volts / 0.65 Amps / 5.2 Watts.

We wired two pair of panels into a series circuit to double the voltage of the output, then wired the pairs together into a parallel circuit to double the current amperage. We the combined unit to a little voltage regulator that feeds a lithium polymer smart battery, which in turn will feed the electronics, motors, and servos of the Mars Rover robot.

Today we wired the panels in series/parallel, hooked everything together, and powered our main Arduino microcontroller. It worked and it was very cool!
