I have revisited the site for my own
edification, and gathered data
from three of three projects-
the tank, the crab, and the
tank/spider. Of these, only the first
tank had the hard timing data -10 to
15 minutes, limited by, as I had
suspected, the amount of water it
was able to carry.
Thinking back to my first couple of
BEAM walkers, 10 minutes was
pretty generous- it was one the things
I had wanted to tweak before pausing
that particular hobby.
I had thought that perhaps ICE's or
mini-turbines would provide a better
source of energy- after all, steam vehicles
aren't all the rage for personal transport- although
I have seen a wood-burning steam-driven
runabout that someone in Australia had built.
In any event, they were just thoughts.
I guess I am biased towards batteries for
powering robots, as the technology is well
understood, widely (and cheaply) available,
and density seems to be improving monthly.
My ideas about energy sources for robots
tend to parallel trends in the auto-industry.
Technologies like hybrids and fuel-cells
seem like they would scale down well,
although it will be a while (IMHO) before
fuel cells are both small and cost-effective.
