Congratulations to the winners of the First Annual Dive In To Earth Day Photo Contest! There were so many wonderful photographs to choose from, but we feel that the following images best capture the spirt of Dive In: a fun, community activity that takes action to protect our marine environment. Winners were chosen from two categories: Above Water and Underwater.
The $60 Desktop Rover is a tiny tank,
about the size of your palm, an inch-and-a-half in height,
and slightly heavy. On each side of it are four wheels and a
horizontal guide, with rubber treads running round them. One of
the wheels on each side is a gear, to drive the tread; each gear
is driven by a small electric motor. Each motor is either going
forwards, going backwards, or stopped, and you steer by combining
these: if both motors are going forwards, the Rover goes forwards;
if one motor is going forwards and the other is stopped or going
backwards, the Rover turns; and so forth.
