It is powered with two 3.3F Goldcaps. They can be charged in a few seconds.
When they are charged, MAXIBUg gets "afraid" of light, and wanders
of to go to play "in the dark". After a while, about 20 seconds
(depending on the current used by the two motors ), the power has dropped,
and it wants to "eat". It gets light attracted, and will turn
and go to the light. When it gets there, it will recharge and still will
be atrackted to the light until it reaches a trigger voltage , at which
it gets "afraid"of the light again. This will go on all day
until someone turns off the lightsource. While doing all this it also
will backup when bumping into something.
