The power of powers. These are just a bunch of little bots I built from junk I had lying around. They are powered by batteries or solar cells.
Sat-bot uses two solar cells to charge a capacitor which is cyclically dumped into a induction coil (an old analog volt meter). I forgot what the circuit is, maybe BeamBot?
Rotatoe does what it name implies, rotates... Kinda funny.
A set of switches acts as a bumper and switches the polarity of the motor thereby driving either forward or reverse.
