The front of the boat had a yellow
water pump capable of collecting water samples. The mechanism for this pump came
from a battery powered electric water gun. I strapped the gun to the top of a
servo and when the servo turned the gun would come into contact with some
carefully placed electric switches to start or stop the water pumping. |

Using my existing RC toy truck, I
strapped the chassis to the top of a couple layers of Styrofoam and replaced the
rubber wheels with paddle wheels. When I first tested the paddle wheels water
ended up splashing all over the boat. Not a good thing for the electric motors
and switches. My quick fix was adding a tape coated cardboard cover over the
paddle wheels to contain the splashing. The drive motor for the paddle wheels was
capable of forward and reverse using a mechanically actuated speed controller. |

The original servo used to steer the car was used for steering a rudder instead
(seen here on the lower left side) Note: the boat in these pictures is
sitting on a Coleman cardboard box which of course isn't part of the boat. |
