Very original. I just learned of fuel cells yesterday on this site. New to me but a bit pricy at the moment. I just started working with a solar panel today… So far learned continous servos work better ( less power) then LM 298 H bridge bot with servos convertted to DC motors. So far I am using strictly solar for now and planning to use cell phone batterys later down the road. I like the unique motovation design. Have you tried it on grass yet? How long does it have to sit in sunlight before being able to store enough gas to move?
Hehe, I have to admit I Hehe, I have to admit I wouldn’t have bought a fuel cell if I hadn’t been able to ‘negotiate’ a special deal on the one I got… As far as power-to-weight ratio goes, you can beat a good rechargeable NiMH or Li-ion battery. Interesting about the servo controllers being more efficient, I was just wondering about how good they were yesterday. Mr. Lobster performs better on grass than on concrete, unless it’s wet, then he has all kinds of trouble =) If he’s totally tapped out of power he can usually get enough energy to start moving after about 2 minutes in moderate sunlight, thanks to the boost converter and the efficient, highly geared motors.
